Vicissitudes in Soldering. Reading and Working with a Historical Gold- and Silversmithing Manual

This month, we’re excited to collaborate with History of Knowledge to celebrate the upcoming conference, Learning by the Book: Manuals and Handbooks in the History of Knowledge. The five-day event takes place at Princeton in June and features a “blogged conference” to complement traditional panel presentations. For the next four Thursdays, the Recipes Project will cross-post selections from the conference (with RP readers noting  the extended length, in keeping with HoK posts). These four features are just a taste of more than thirty works produced for the conference, and readers are invited to read the full selection here. Enjoy!


Thijs Hagendijk and Tonny Beentjes

In 1721, the Dutch craftsman Willem van Laer (1674-1722) published a Guidebook for Upcoming Gold- and Silversmiths. Intended as a manual to educate young novices, the Guidebook discussed a variety of different practices, techniques, and skills that ranged from assays to determine the quality of precious metals to sand mold casting and polishing (Figure 1). Four different editions, including one pirated copy, appeared in less than fifty years, attesting to its popularity. The book was explicitly aimed at teaching young readers how to do and make things. Van Laer reassured readers by saying “there will be few young gold- or silversmiths, who won’t find anything to their liking and benefit while reading this book; they will be led by hand to the knowledge of many things.”[1] Yet, however confident Van Laer might come across in this passage, there is sufficient reason to question the actual success of Guidebook at explaining and delivering these skills. Practical knowledge is often better demonstrated than written down. Van Laer was very well aware of this fact and offered disclaimers warning his readers that full comprehension of the text was only achieved when complemented with manual instruction. This begs the question of what could, in fact, be learned from the Guidebook.

The best way to answer this question is to look at historical evidence, primarily in the form of marginalia or other signs of usage, that indicates how the Guidebook was read and used on the shop floor. Unfortunately, not much of this evidence has survived for reasons that historians Natasha Glaisyer and Sara Pennell have observed in their study of early modern didactic literature. They note an irony in the fact that books that were most read and used did not make it to our libraries.[2] Indeed, most Guidebooks that reside in Dutch libraries are neat and almost spotless copies – we even found a copy with its pages still uncut! (We ended up cutting its pages almost three hundred years after publication, but that is another story). This virtual lack of historical evidence pushed us in a different direction. We decided to approach the Guidebook experimentally by performing historical re-enactments. By reading and working with the text as if we were learning how to make and do things, we were able to get a better grasp of Van Laer’s potential audience and the role the book might have played in historical learning practices and the acquisition of practical skills. The re-enactments gave rise to various insights.[3] In this post, we discuss one specific result, which is a story involving both success and failure.

Part of Van Laer’s discussion of soldering features the introduction of a “convenient soldering lamp.” Even though the better part of soldering usually happened in the forge, Van Laer presents his soldering lamp so that “the maker won’t need to put the entire piece back into the fire for a tiny leak or mistake only.”[4] For a silversmith, putting a soldered piece back into the fire was always risky as the soldered joints could melt again and cause more trouble than initially was the case. The preferable method was to repair a soldered piece without having to expose it again to relatively high temperatures, which is where the soldering lamp comes in. Basically, the soldering lamp resembles a modified oil lamp with an extended snout. To reach temperatures high enough to melt the solder, one had to use a small blowpipe to blow additional air through the flame. Skillful blowing would subsequently result in a second tiny yet feisty blue flame hot enough to locally melt silver. That is, at least, what Van Laer seemed to suggest: “when the tip of the flame of such burning Lamp is blown against the spot that needs to be soldered, it makes it hotter over there and the solder will easily run.”[5]

To find out whether we could indeed solder this way, we decided to build a soldering lamp following Van Laer’s instructions. Luckily, Van Laer was meticulously detailed with respect to the lamp, discussing its dimensions and the materials needed to produce it. According to him, the lamp should be made from brass and should measure 3 inches across and 1 inch in height. Additionally, there should be a wooden handle at its back and at the front a snout of about 5 or 6 inches long. To make sure he was well understood, Van Laer also included a schematic engraving of the lamp (Figure 2). We had more than enough information to work with, and based on his drawings and instructions we produced a much-desired replica of the lamp (Figure 3). We also laid our hands on a few historical blowpipes. Now that we had the materials, we could learn to handle the tool.

We filled the lamp’s reservoir with olive oil and stuffed its snout with a cotton lump. When we finally lit the lamp, the burning oil filled the room with a scent of grilled food. As an initial exercise, we took a small brass strip and tried to heat it until it started to glow. Here is how it went down, as recorded by Thijs in our fieldnotes:

Glowing the metal strip did not happen before we learned our first big lesson. Intuitively, Tonny and I started out by blowing hard through the blowpipe. The more air, the hotter the flame we thought. After trying for quite some time, it seemed as if we weren’t making any progress. We could steer the yellow flame, but were not able to get the blue flame where we wanted it. Yet, after I tried some more, it suddenly appeared that I had been blowing way too hard. By blowing rather softly on to the flame, suddenly the little blue flame emerged. In general, the blowing required much exercise. When later that afternoon a visitor dropped by for an interview, we saw the amount of skill that we already acquired. She too tried to produce a feisty blue flame by blowing through the flame, but did not succeed. To my own surprise, I was immediately able to point out what went wrong. The tip of the blowpipe should almost touch the pit of the flame, while one should blow out of the flame, both from beneath and from the inside-out. Cheeks filled with air, meanwhile breathing in, breathing out, breathing in, breathing out, filling the cheeks again and keep blowing at the same time. A rhythm occurs in blowing and breathing, which maybe most resembles what happens to your breathing when running.(Fieldnotes Thijs, April 4th, 2017).

Until this point, then, the story was quite successful. We were able to reverse-engineer the soldering lamp, and, like Van Laer explained, we could reproduce the feisty blue flame. Moreover, the blue flame proved rather hot indeed, as indicated by the different oxidation colors on the brass strip. However, as soon as we tried taking it to the next level, we ran into trouble.

Still happy with the progress we made, we now wanted to solder a very basic joint. We took another brass strip, hammered it round, and set out to solder its ends together to make a tiny cylinder. We fixed the cylinder in a standing pair of tweezers to free both our hands so we could steer the soldering lamp and hold the blowpipe. A little piece of solder was put on top of the joint, as well as little bit of borax, which is a flux used to facilitate the flow of melted solder. We lit the lamp and started blowing (Figure 4).

One hour later we were so out of breath that we stopped, but the cylinder had not yet been soldered. We failed. Even though we raised the temperature high enough to make the solder curl up like a drop, we never reached the final state in which it flows out and runs into the joint. Using the soldering lamp appeared less straightforward than we thought it would be.

We were curious to know what went wrong, but after several more days of trial-and-error, the list of questions and issues had only grown. We turned to the Guidebook and read and re-read the passages, only to discover that Van Laer was actually quite silent on the matter. Indeed, he carefully described how to assemble the soldering lamp, but spent hardly any time on how to handle it in practice. Should the object be pre-heated, or could the soldering lamp be used on cold objects, too? We blew and soldered against a piece of charcoal to create a reverberating heat source, but was this also how Van Laer meant to use the soldering lamp? Moreover, what type of solder should we use? Van Laer listed three distinct recipes for solder with different melting points, but did not indicate which one to use in combination with the soldering lamp. To date, we still have not been able to solder a proper joint using the lamp.

Interestingly, if we compare the above experiences with other re-enactments we performed, a general pattern starts to emerge.[6] For example, with respect to sand mold casting, Van Laer vividly described how to prepare and process the sand, but left his readers hanging when it came time to assemble a mold from it. Moreover, in his discussion of chasing, he meticulously described how to transfer a design to silver, but gave no guidance on how to perform the actual chasing process. Why would Van Laer alternate between exacting detail and virtual silence? What does this say about the usability of the book? And what could, in fact, be learned from this text?

The soldering story followed a similar pattern. While Van Laer carefully discussed each and every condition needed to succeed – the soldering lamp, recipes to prepare multiple types of solder, different sorts of fluxes – we failed once we arrived at the procedure itself. Is this due to our lack of skill in operating the blowpipe and soldering lamp, or are there aspects of eighteenth-century soldering that we no longer understand? In any case, the Guidebook’s guiding principle seems to be that core operations are best demonstrated rather than put into words. Van Laer did in fact confirm this with respect to the casting procedure. Just as he came to the very heart of the procedure, he abandoned his detailed exposition, stating that “the molding and casting cannot be learned as well as through manual education.”[7]

During our re-enactments, we therefore came to interpret the Guidebook as a text containing advanced practical knowledge, including tips, tricks, and best practices. Learning new skills from scratch, such as soldering, casting, or chasing, is still best done through manual education, but once mastered, the Guidebook can indicate new routes, spell out different paths, and show new variations on a theme.

Making Senses: Artisanal Practice and Sensory Perception in an Early Modern French Manuscript

By Tillmann Taape

Ms Fr. 640 was written in French by an unknown craftsperson in Toulouse, likely between 1580 and 1600. [1] It is an intriguing and eclectic source, with entries ranging from medical recipes to metalwork and pigment-making, and it forms the core of the Making and Knowing Project at Columbia University, introduced previously on the Recipes Blog in a post by our Director, Pamela Smith.

With its numerous instructions for making things, our manuscript provides a rich case study for the way artisans worked with and thought about materials. As previous posts in this series on Recipes and the Senses have shown, physicians, alchemists, apothecaries, and other craftsmen recognised in their bodies and its senses an important set of tools for understanding and manipulating the material world, and historians pay increasing attention to these embodied and sensory ways of knowing. In this post, I will share a few examples of the rich language of the senses in Ms. Fr. 640. As one might expect from a manuscript including painting and sculpture, the eye often takes precedence over the other senses. However, a discussion of the visual in the manuscript would by itself be far beyond the scope of a single post – we spent much of this year just trying to figure out how the author-practitioner conceptualises different pigments and shades of blue. The aim here, therefore, is to focus on the oft-neglected non-visual senses and what they can teach us about our author-practitioner’s concept of the material world, his ‘material imaginary’.


A strong smell was often a sign that things had gone wrong – the papier-mâché had turned rotten while being left to soak, or a kitchen pot had been made with too much latten (a copper alloy), which ‘stinks and smells bad’ (fol. 36v). However, smells could also help identify the materials needed for a recipe. The ingredient list for a metal alloy, for example, includes the intriguingly specific ‘congealed mercury with the smell of tin’ (fol. 92v). Musing on one of his favourite topics, the properties of fine sand used for metal casting, the author-practitioner notes that

white sand smells like sulphur when heated, and I believe it would melt. And as the substance has been cast in it, it acquires in the mold a lustre as if it were leaded or vitrified. I believe that glassmakers could use it (fol. 99r).

In addition to his observation of a vitreous glaze on the cast object, it is the sulphurous smell which suggests to the author-practitioner that this particular kind of sand is prone to melt and could even be used for making glass. Throughout the manuscript, sulphur does indeed appear as a material which can easily be melted and used to cast small objects, and even appears to function as a sort of material metaphor for transformation and experimentation.


The sense of hearing becomes itself the subject of a short entry. Under the heading ‘hearing from afar’, the author-practitioner records one of the tidbits of advice and tricks for daily life which are scattered here and there throughout the manuscript: ‘Make a small hole in the ground, put your ear against it during the night or during a quiet time, and you will easily hear muffled sounds’ (fol. 125r). In addition to facilitating amateur espionage, specific noises could serve as helpful indicators in the workshop. Before casting metal into a mould made from cuttlefish bone, the author-practitioner writes, one has to make sure that it is completely dry: ‘you will know that they are dry enough when, after having held them near the fire a little, their inside and the impression scream & crackle when you hold them up to your ear’ (fol. 145r). If one was prepared to listen carefully, the materials themselves could tell when they were ready to be worked upon.

The sense of taste could also help to assess and adjust one’s materials. To make ‘essence of sal ammoniac’, for example, ‘the size of two chestnuts of pulverized sal ammoniac suffices in a pot of water, and to the tongue you find the water moderately salty, for too much is not good’ (fol. 111v). The concentration of the sal ammoniac solution was clearly of some importance here, and like in most early modern recipes, the given measurements – size of a chestnut, a pot of water – might not yield very consistent results, so a qualitative sensory indication – ‘moderately salty’ – is added as a further point of reference. As well as checking one’s own procedures, taste could of course be used to assess the quality of merchandise. The city of Toulouse, where our manuscript was compiled, gained much of its considerable wealth from the trade in woad, a blue dyestuff whose French name, pastel, is a likely origin of the term ‘pastel’ colours in English and other European languages. It is not surprising, therefore, that the author-practitioner mentions this sought-after material and tells us how to tell the good from the bad. This involves several steps, including inspection and a dyeing test, but the first step is a taste test: ‘The goodness of the woad is known when, put in the mouth, it gives a taste as of vinegar’ (fol. 39r).


Perhaps unsurprisingly for someone who clearly worked with his hands a lot, the sense of touch plays a particularly important and intriguing part in the author-practitioner’s practice and writing. Returning to his favourite topic – the different kinds of sand or plaster used for casting moulds – he describes how the addition of a substance called alum de plume (literally ‘feather alum’ – it probably refers to a group of minerals known as feldspars in English) helps the mould hold together because it forms fibrous structures (hence probably the reference to feathers). Its production requires a complex process of heating and grinding up in a mortar. In the margin next to the recipe, the author-practitioner notes that one should grind the alum slowly and in small portions, and finally ‘render it very fine & soft to the touch’ (fol. 108v). The manuscript is full of these kinds of haptic properties to indicate the appropriate consistency or particle size of materials. Another ‘sand’ for casting, for example, is made with ‘the bone of oxen feet, very burned & pulverized & ground on porphyry, until it is not felt between your fingers’ (fol. 84v). Intriguingly, here the reader is told to stop grinding not when they can feel a particular sensation, but when they can no longer feel the material at all with their fingers.

As it turns out, this criterion of eluding the sense of touch was an important technical concept for early modern artisans. Our former Making and Knowing postdoc Jenny Boulboullé and former students, Raymond Carlson and Jordan Katz, have shown that the term impalpable, that is to say ‘un-feelable’ or ‘impalpable’, is central to the way the author practitioner experiences and thinks about different kinds of materials used for casting moulds.[2] Furthermore, they found that he is not the only one: the use of the term ‘impalpable’ is used in published works on metallurgy, such well-known book Pirotechnia by the sixteenth-century Italian founder and metallurgist Vanoccio Biringuccio, and the Secreti, a famous book of secrets attributed to Alessio Piemontese. In his emphasis on the haptic sensation of a material being impalpable, then, the author-practitioner speaks to a sensory terminology apparently widely shared by expert makers.

Describing specific sensory experiences can be difficult, and it makes sense to refer to well-known parallels from daily life – a smell like sulphur, a taste like vinegar, and so on. When it comes to the sense of touch, too, the author-practitioner relates processes described in his recipes to everyday practices. As our former student Emma Le Pouésard has shown, the practices surrounding making bread were a particularly fruitful source of these kinds of comparisons.[3] To unmould a cast object, one should ‘strongly separate the moulds as if you wanted to tear bread apart’ (fol. 114v). In an age before thermostats, this could even provide a way of gauging consistent temperatures. For one’s domestic taxidermy needs, the author-practitioner writes, one could dry animals ‘in an oven as warm as when bread has been taken out’ (fol. 129v). In a recipe for making stucco, bread making is used as a referent for working up the right kind of consistency: the recipe tells us to ‘knead as if you wanted to make bread’, until the stucco paste is ‘firm as bread dough that is ready for the oven’ (fol. 29r).

When we tried making stucco in the Making and Knowing Lab in the Fall semester, this proved to be very useful guidance. While we were not experienced bakers in the way that many early modern householders probably were, we could draw on our experience from one of our ‘skillbuilding’ exercises a few weeks earlier, when we made bread to use as a mould for wax casting, replicating one of the most intriguing processes in the manuscript. When it came to making stucco and mixing the right amounts of tragacanth gum and rye flour or champagne chalk, the author-practitioner’s instructions about kneading to a consistency like bread dough were very useful, especially in the absence of any other indication of measurements. By adding flour until we achieved a dough-like mass which would ‘stretch enough without breaking’ (fol. 29r), we eventually produced stucco which displayed fine detail and could be detached from the mould without too much trouble.

Even this brief tour of Ms. Fr. 640 shows that much is to be gained by paying attention to the non-visual senses in recipes and practical instructions. In the absence of precise standardised measurements and procedures, sensory descriptions were paramount to articulating a material’s properties, whether it was of good quality, or how much longer it needed to dry, boil, soak, or be crushed in a mortar.

Tales from the Archives: Smelling ‘Violet’ in Renaissance Works

In 2017, The Recipes Project celebrated its fifth birthday. We now have nearly 650 posts in our archives and over 160 pages for readers to sift through. That’s a lot of material! (And thank you so much to our contributors for sharing such a wealth of knowledge on recipes.) But with so much material on the site, it’s easy for earlier pieces to be forgotten. So, the editors have decided that, every now and then, we’ll pull something out of the archives to share with our readers anew.

This month’s we re-feature a post by Colleen Kennedy, first published in August 2013. I think that it fits very well with our conversations this month, don’t you?

Enjoy the spring flowers, everyone!



By Colleen Kennedy

The violet (Viola odorata) is cited in several herbals and many recipe books as a particularly sweet scented, fragrant flower. Herbals, such as Culpeper’s, describe the violet as a “cold and moist” plant, with many medicinal qualities. It is used as a laxative, and as a treatment of syphilis and uterine complaints; it counterbalances choleric humors, is good for many lung ailments, eases headaches and sleeplessness, and is a general panacea.

Violets are also commonly used in recipes, either as “cakes of violet,” “candied violets,” “conserve of violets,” or “syrup of violets,” as flavoring for metheglins (meads), and to add aromatic qualities to vinegars and other recipes:

To Make Syrup of Flowers:

Take of Violet flowers fresh and pickt, a pound, clear water boiling one quart, shut them up close together in a new glazed pot a whole day, then press them hard out, and in two pound of the Liquor, dissolve four pound and three ounces of white Sugar, take away the scum, and so make it into a Syrup without boiling. (Woolley 6)

Any of Hannah Woolley’s recipe books are a good place to begin to study early modern recipes utilizing violet flowers. Violet’s pleasant odor is also the source of its medicinal powers and cause for its common domestic usage.

Hannah Woolley's The Accomplish'd lady's delight in preserving, physick, beautifying, and cookery (1675)
Hannah Woolley’s The Accomplish’d lady’s delight in preserving, physick, beautifying, and cookery (1675)

So, what does the violet smell like?  English, alas, lacks a smell-vocabulary, and violet is repeatedly only listed as “sweet” or “fragrant.” Avery Gilbert considers the two distinct “voices” available to modern perfume makers: “Ingredient Voice” (the actual list of and proportions of ingredients) and “Imagery Voice” (“atmospherics, the drama of seduction, passion, and mystery”) (15). It is in that latter voice that we move closer to the more detailed early modern accounts of the aroma of violet.

For example, modern perfume blogger Normand Cardella, in his review of Yves Saint Laurent’s Paris, muses on the smell of violet: “So… what does a violet note smell like?  Well… it’s powdery, a little sweet and decidedly sad.  Musically, a violet note in perfume would be a minor chord.”

Likewise, for early modern writers, the violet is also a sad  and musical aroma. Francis Bacon, in his essay “Of Gardens” (1625),  links pleasurable odors and sounds (and much earlier than our modern perfumers): “And because the breath of flowers is far sweeter in the air (where it comes and goes like the warbling of music) than in the hand, therefore nothing is more fit for that delight than to know what be the flowers and plants that do best perfume the air”. Violet is his favorite perfumed flower: “that which above all others yields the sweetest smell in the air is the violet”.

The violet’s “imagery voice” is most fully articulated in Duke Orsino’s opening lines of Twelfth Night:

“Orsino and Viola” by Frederick Richard Pickersgill (c. 1850)

“If music be the food of love, play on.

Give me excess of it that, surfeiting

The appetite may sicken and so die.

That strain again, it had a dying fall.

O, it came so o’er my ear like the sweet sound

That breathes upon a bank of violets,

Stealing and giving odour. Enough, no more.

‘Tis not so sweet as it was before.” (1.1.1-8)

Much of the language here that applies to music or love is equally applicable to the sensation of smelling violets,  especially violet’s unique chemical compound and its effect on the sense of smell. As Diane Ackerman describes: “Violets contain ionine, which short-circuits our sense of smell. The flower continues to exude its fragrance, but we lose the ability to smell it. Wait a minute or two, and its smell will blare again. Then it will fade again, and so on.”

The discovery of its isomer ketones did not occur until the late nineteenth century, yet, its affects were all very real experiences for early modern writers, such as Shakespeare, who attempt to distil and capture the essence of violet in distinctly beautiful terms, with the violet “stealing and giving odours.”

The “dying fall” of Orsino’s sad tune is like the melancholy aspects of the violet, evoking impermanence, transience, and death. Even Orsino’s command to stop the music can also describe the anesthetic properties of ionine.  As Orsino complains though, the scent, the song, the sensations, and so on is “not so sweet as it was before.”

John Gerard's "The herball or Generall historie of plantes" (1633) Chapter 312: Of Violets
John Gerard’s The Herball or Generall Historie of Plantes. (1633) Chapter 312: Of Violets

Orsino’s very mind, in its melancholic state, is affected by sweet airs—whether sad songs or fragrant violets. As the early modern brain was believed to be acutely affected by odors, and the violet emits a particularly sweet and sad aroma, the botanist and herbalist John Gerard’s regard for the violet’s olfactive and affective properties should not be surprising:

[Violets] haue a great prerogative aboue others, not onely because the minde conceiveth a certaine pleasure and recreation by smelling and handling of those most odoriferous flours, but also for that very many by these Violets receive ornament and comely grace …And the recreation of the minde which is taken hereby, cannot be but very good and honest: for they admonish and stir up a man to that which is comely and honest… do bring to a liberall and gentle manly minde, the remembrance of honestie, comelinesse, and all kindes of vertues. (Chapter 312: “Of Violets” 849-850)

Gerard nicely summarizes the memorable, virtuous, affective, symbolic, and olfactive properties of the violet that we have been sniffing out in this brief essay.

Gershom Bulkeley (1635-1713): A Sensory Chymist in Colonial Connecticut

By Donna Bilak

Who was Gershom Bulkeley? (you may well ask). A Harvard-educated Puritan gentleman from an important New England family, Bulkeley spent most of his life in Connecticut as a colonial divine, physician, and magistrate of upstanding (and by contemporary accounts obstinate) character. Bulkeley was also an iatrochymist – an aspect of his work that is only now starting to receive scholarly attention – and prolific compiler of notes about the medico-alchemical experiments that he conducted in his laboratory, likely a part of his dwelling place.

About 25 miles from where Bulkeley once lived, there now exists a kind of biblio-bunker in the University of Connecticut Health Center. This is where the Hartford Medical Historical Society Library keeps its collection of rare books and manuscripts. And this is where twenty-four manuscripts that are either by or associated with Bulkeley ended up. NB: there is treasure buried in this underground archive! (I am sure that as a Puritan with millenarian expectations, Gershom himself would be comforted to know that in the event of some kind of apocalyptic event, his notebooks will survive intact.)

I came across this cache back in 2011 while chasing down different leads for my dissertation about one of Bulkeley’s contemporaries, another Harvard-trained Puritan minister-physician-alchemist named John Allin (1623-1683). But in going through the various manuscripts, I was drawn to one of Bulkeley’s notebooks in particular: Bulkeley MS 5.

This is a small book that has been rebound using the cover from a 19th-century book of fairy tales, and it contains a series of entries about alchemical experiments that Bulkeley undertook between 1703 and 1706 scrawled across eight pages, with an additional sixty-three pages oriented upside down at the back of the book of more extensive laboratory notes of ongoing experiments, dated 1702 to 1707. At some point in time, both sets of notes were bound together with Bulkeley’s (undated) abridged copy of the Institutiones medicae by Lazare Rivière (1589-1655) – i.e., two hundred and forty-four densely written pages of Latin in a neat and minute hand ­– sandwiched between the aforementioned two sets of laboratory records. Intriguing stuff…

…because Bulkeley crammed this notebook full of particulars about chymical substances, instrumentation, and techniques. Bulkeley worked with different chymical substances for pharmaceutical production. His recorded experiments are filled with actions (tasting, weighing, drying, stirring, observing, waiting), and his laboratory entries document a range of output (he made salts, spirits, powders, pills, oils, dissolvents, elixirs). In their preparations, Bulkeley worked with iron, copper, and antimonial substances, as well as mercury, arsenic, silver, coral, and turpentine, and he used various chymical processes (calcination, coagulation, sublimation, evaporation, distillation). Bulkeley also detailed the equipment he used, describing things like various retorts (one is silver) and curcurbits (a glass one, a silver one), heavy and light scales, a blue jug, a copper vessel, an alembic, a receiver.

Another striking feature of this notebook is Bulkeley’s use of naked senses – taste, touch, and sight – as tools of investigation in his experiments. Bulkeley describes the consistency of experimental matter in comparison to common foodstuffs (“pudding” features large in his notes as a standard for assessing viscosity). Bulkeley also records the presence, or absence, of “lixiviate”, “vinegar”, “alcalisate”, or “urinous” tastes; interestingly, these references to tasting generally occur (when they do) at the conclusion of a given entry. Bulkeley’s haptic perception in the lab comes across in three entries, which record experiments that took place between January 27 and February 1, 1702. Here, Bulkeley detailed a distillation process involving nitre, mineral iron, and oil of vitriol (the objective appeared to be the production of aqua fortis), whereby an outcome of these distillation experiments was to harvest the caput mortuum.

Bulkeley observed that the dregs from January 27th “looked pretty white,” while that from January 29th was reddish, and he concluded with the comment, “Both the Cap. mort came out easily enough & crumbly but the 2d was not so soft & easy as the first/”. This seems to indicate mixed results in Bulkeley’s estimation. A third (and likely final) entry dated February 1 indicates the continuation of this experiment, with some changes in ingredients (i.e., the addition of flowers of sulphur) and procedure (Bulkeley undertook the sublimation of the matter in question). Notably, Bulkeley recorded that he did not lute his receiver (meaning that he did not undertake the preventative measure of smearing a claylike compound around this vessel to seal and thusly protect it in heating procedures).

This time, things did not go so well with the experiment:

I could not get no more off the broken pot: & flowers in the head that I could save, [6…] : that is in all. But it was the same pitcher in which I had destilled A. F. put in before, suc. Janr 27. & 29. & now it was cracked & had leaked a little out into the sand, had drunke up some into it; & I could not get the Cap. mort cleane off, nor the flowers absolutely cleane: & tis very Pbable some might evaporate, the Rec. not being luted on./ The sulphur in the Capt Mort was not fixt, but which upon a coale readily smoake & flame burne with a very fine blew flame./

These entries about the caput mortuum show Bulkeley’s bodily way of knowing as a form of assay, a testing procedure that links sensory analysis with chemical analysis in his evaluation of the progress of his work. This also shows that Bulkeley paid just as much attention to detailed sensory descriptions of his failures in the lab as he did to successes.

Bulkeley MS 5 is a valuable artifact of Bulkeley’s heuristic laboratory methods in the production of chemical pharmaceuticals, likely destined for use in his medical practice. While this notebook presents us with puzzles (what prompted its compilation? how was it used?), at the same time we are granted open access into Bulkeley’s experimental activities, a window into his dynamic medico-alchemical operations in a colonial community at the turn of the 18th century.
