Recipes for the Inner Chamber: Vernacular Manufacturing in Early 20th Century China

By Eugenia Lean

In the 1910s, a curious print culture phenomenon appeared in China’s urban areas.  Journals such as the Ladies’ Journal (Funü zazhi) and Women’s World (Nüzi shijie) began to run columns and articles that provided recipes for manufacturing soap, hair tonic, perfume, and rouge at home.[i] They often explained the chemistry behind the manufacturing process and promoted the use of modern lab equipment and glassware to produce the desired items. The pieces deemed their detailed technical manufacturing information as highly appropriate for genteel women to apply in their inner chambers.

A typical example of the gendered portrayal of domestic manufacturing in these publications can be found in the piece titled, “An Exquisite Method for Manufacturing Hair Oil,” that appeared in first run of the Women’s World (1914–1915) column, “The Warehouse for Cosmetic Production” (hereafter, “The Warehouse”), and its companion piece that appeared in the February issue. As the editor noted in the February entry, the first article had elicited much interest and a woman reader by the name of Mme. Xi Meng had already sent in a request for more tips (Tianxuwosheng 1915, 3). The February issue included a recipe for hair tonic, which listed its ingredients in both Chinese and Latin:[ii]

  • 純粹硫酸                                                      Acidum Sulphruicum [sic]
  • 檸檬油                                                          Oleum Limonis
  • 精製植物油即前節製原料法中自製之油
  • 玫瑰精                                                          Spiritus Rosae
  • 硼砂                                                              Borax
  • 橙花水                                                          Aqua Aurantii Florum
  • 酒精                                                              Spiritus
  • 洋紅細粉亦須自製
  • 丁香油                                                          Nelkeuöl [sic]
  • 肉桂油                                                          Oleum Cinnamomi
  • 橙皮油                                                          Oleum Aurantii Corticis
  • 屈里設林                                                      Glycerin
  • 白米澱粉即本節製法中自製之水磨粉
  • 白檀油                                                          Oleum Santali

(Chen Diexian 1915, vol. 2 [February], 4)

Many of the items could be purchased in Shanghai’s pharmacies, but since spiritus rosae was particularly expensive, the editor wanted to make its recipe readily available. The recipe instructed:

Extract the fragrance of fresh flowers, and attach it onto something solid, so that it lasts and does not disappear. There are many ways of doing this. One can use a method for suction; the method for squeezing, the method for steaming, the method for soaking. None of these are as ideal as the method for absorption. To make spiritus rosae, use the method for absorption (Tianxuwosheng 1915, 6).

What followed was a highly detailed and technical description of how to achieve this method at home. The tools, instruments, and materials needed include bottles, tubes, alcohol burners, hydraulic acid [sic], and no less than five pounds of marble.

China had a long history of manufacturing cosmetics at home. The knowledge behind this domestic production tended not to be written in recipes, but was embodied and passed down from generation to generation. Domestic producers would thus not have been likely consumers of these printed recipes.

As urban consumption of makeup and toiletry items grew in the 1910s, manufacturing such items at home would also seem less pressing. To understand why these pieces appeared when they did — and who was consuming them and why, it is worthwhile to consider what was unprecedented about them.

Appearing in China’s burgeoning mass media, new-style columns like “The Warehouse” made certain skills public, presented them in new terms for new purposes, and made them readily available for a far greater reading and practicing audience than ever before. The new epistemological frame within which the knowledge was presented (chemistry and physics) and the material accoutrement (lab equipment and modern glassware) stipulated as necessary also attracted readers.

The application of these recipes would have required considerable investment in resources and time. Chemistry knowledge was necessary and some called for considerable lab equipment. The instructions to manufacture the spiritus rosae ingredient for hair oil, for example, listed the following items as necessary:

Alcohol Burner—1; Alcohol—2 lbs; Glass tube of 2 centimeter diameter—½ stem; Long-necked glass funnel—1; Double-opening bottle—1; Washing ‘gas’ bottle—1; Wide-mouth bottle that holds 1 lb—1; Wide-mouth bottle that holds 5 lbs—1; Marble—5 lbs; Hydrochloric acid—1 lb (Tianxuwosheng 1915, 4).

Given the nascent state of China’s glassware industry, chemical apparatuses were often imports and available for purchase at a cost at exclusive scientific-appliance stores such as Shanghai’s China Educational Supply Association. Once producers procured the ingredients and equipment, they then had to follow detailed instructions.

To achieve the method of absorption, practitioners were instructed to drill holes into stoppers that were to plug the glass bottles; the holes had to be large enough for a glass tube and funnel to be inserted; the glass tube then had to be bent. Instructions on how exactly to use an alcohol burner to heat the glass and mold it to the appropriate shape were provided.

While genteel women were the supposed readers of these recipes (and those with the curiosity, means and knowledge to apply these recipes could have done so), participants in the reading community of these recipes included men. Male consumers of these pieces included connoisseurs of technology, dabblers in chemistry, young students and budding industrialists.

It was far from automatic for the well-educated, male or female, to turn toward production and manufacturing as the literati had long felt a severe distaste for hands-on engagement with things for subsistence or commercial purposes. Yet, by 1915, there was a growing sense that this was necessary. The persistence of internecine warfare and imperialist aggression dashed the initial hopes of the 1911 republican revolution. With the chaos of republican politics threatening national strength many of China’s lettered men and women started to explore new regimes of knowledge and experiment with new social and occupational roles, including those of the once taboo realms of industry, manufacturing and commerce.

It was in this context that these recipes helped cleanse the hands-on work in industry and manufacturing of its negative connotations. These “how-to” pieces became sites where experiential engagement with chemistry and manufacturing was promoted as crucial in strengthening China, as well as a sign of good taste and bearing. They became part of the arsenal of strategies available for readers navigating their new cosmopolitan identities in a post-civil-service-examination arena of urban playgrounds and industrial centres. By appreciating these pieces with a sense of refined curiosity or in a posture of playful leisure, readers could define their sense of exclusivity based on notions of production that were tasteful and authentic in terms of their scientific, domestic, and noncommercial nature.

The domestic realm as a site of production also served as a metaphor for the larger marketplace in treaty ports that existed beyond the reach of the state. There, scientific, commercial, and manufacturing knowledge increasingly displaced moral knowledge and statecraft as the preferred epistemological foundations for a competitive nation.

Just a few years later, a strong reaction rose against presenting chemical experimentation and manufacturing as a dilettantish endeavor appropriate for genteel women. With the May Fourth Movement in 1919, Sai Xiansheng, or “Mr. Science,” would emerge as part of the slogan “Mr. Science and Mr. Democracy,” and science was, along with democracy, promoted as the foundation of a powerful nation. The portrait of the genteel woman engaging in leisurely production of cosmetics at home became emblematic of a “traditional” culture that had long fettered China’s modernization.

These recipes have been long overlooked by historians as insignificant as a result. Yet, they deserve to be reconsidered. Though they vanished quickly from the pages of China’s urban periodicals, they were historically significant. They were indicative of a period before science and manufacturing had been formalized in China and when efforts to learn and do industrial production was “vernacular,” occurring in ad hoc, informal and curious places (Lean 2020).

A couple of ingredients are not listed in Latin. Glycerin is English and Nelkeuöl, which is misspelled in the article, and should be spelled Nelkenöl, is the German word for oil of cloves. The first ingredient, sulfuric acid, is also glossed and spelled incorrectly as “Acidum Sulphruicum.” The foreign-language rendering of several of the ingredients helped establish that sense of cosmopolitanism. Yet, mistakes were present and speak to the complex nature of the translation process and the diverse linguistic circuits these recipes traversed.

Waste Not, Want Not: Transforming Waste into Food – Skimmed Milk

By Lesley Steinitz

Fancy some pig’s wash with your granola? In the late nineteenth century, the ‘pig’s wash’ – a euphemism also for vomit – was skimmed milk. It was so-named because it had been the sour leftovers after the cream was skimmed off milk left out overnight in the dairy. Although some ‘skim’ was used to make cheese and feed poor agricultural workers, it was so disgusting that most of it was fed to pigs. Skimmed milk remained disgusting in the minds of consumers even after dairies were mechanised, from the 1880s, once it had changed materially into a fresh sweet liquid. It sold, at best, for a quarter of the price of whole milk, but philanthropists couldn’t even give it away to the poor.

From the perspective of nutritional chemists, this was a waste of a valuable source of protein at a time when dietary deficiency was a grave political concern, linked to worries about the fitness of the workforce and its implications for industrial productivity and military security. This waste therefore spurred innovation among commercially-oriented engineers and chemists at the turn of the twentieth century.

Chemists devised noxious industrial-scale chemical processes which transformed skimmed milk into near-identical protein powders. These contained around 90% milk protein and 5% phosphates, and were off-white, insubstantial, odourless and flavourless. They didn’t resemble food in the slightest. It’s instructive to compare how the two most advertised brands in Britain, Plasmon and Sanatogen, were advertised.

Plasmon’s adverts presented it as a cheap nutritious food, using numbers and pictures to signify its protein’s muscle building power. To persuade people to cook with it, they ran cookery competitions, published recipes, and persuaded famous people – notably the vegetarian health writer and sports champion Eustace Miles – to do so. However, these efforts backfired. Plasmon and Miles were lampooned regularly. The Evening Post derided Plasmon as an uninviting food made by ‘nutrient necromancers’, while the Daily Express declared that this ‘food of the future’ did not satisfy the social and cultural expectations of food as something to enjoy and share.[1] Only Plasmon Oats and Cocoa, where Plasmon was mixed with familiar foods, remained popular.

Although it was near-identical, Sanatogen was positioned primarily as a nerve nutrient thanks to its phosphates (which are present in high concentration in the nerves and brain). Sanatogen therefore addressed another dominant health concern, ‘nerve weakness’, often referred to as the new disease category of neurasthenia. It was therefore not simply a food, but a ‘food-drug’, something that was ‘taken’ like a medicine before meals, rather than as part of them. There were no recipes, simply instructions on how to prepare a dose. With advocates including MPs, doctors, respected writers and aristocrats, and adverts with inspiring quotes from Shakespeare and Goethe, this was an aspirational product which sold for twice the price of Plasmon. You can still buy Sanatogen today.

At much the same time, engineers devised mechanical preservation methods. Their machines sprayed milk, skimmed or whole, onto steam-heated spinning metal rollers where it condensed instantly, forming a powder.[2] (While dried milk had been produced during the nineteenth century, the slow heating methods tended to cook the milk and caramelise its sugars, so it could only be eaten if it was disguised mixed in other foods.) Manufacturers, competing on cost, largely could not afford to advertise their dried skimmed milk. Exceptionally, Cow & Gate published recipes using it, but I’ve yet to find any in ordinary cookbooks, though when fresh milk was scarce in wartime, newspapers suggested using dried instead. Consumers were largely oblivious to the nutritional benefits of this ingredient and to its abundance in industrially manufactured foods such as bread, biscuits and chocolate, and in canteens and institutions. There are few traces before 1920 of people using it domestically other than the full fat versions for infants.

These foods were not popular thanks to their intrinsic palatability, convenience or physiological effects, but instead reflected the cultural characteristics that advertisers linked to their nutritional claims. Expensive Sanatogen was aspirational because it was presented as a respectable medicine-like supplement used by the elites. Cheaper Plasmon was less successful because this peculiar food seemed ridiculous. For consumers, the even cheaper dried milk was an alternative infant food, but was thought to be unsuitable for adults. The positioning of these three similar products demonstrates that food choices are far more than a rational choice relating to nutrition and economy. Now protein powders and skimmed milk are popular commodities. The change in their popularity illustrates how food manufacturers wield considerable power over consumers by leveraging nutritional ‘facts’ alongside cultural values to suit their commercial aims.

Beauty and the Beaumont Magazine: Transgender Make-Up

By Daisy Payling

For Charlie Craggs, transgender activist and nail artist, make-up is vital. Interviewed by Stylist in February 2019, she spoke about its transformative power:

“Some people think beauty is trivial. As a trans woman, I believe it’s a privilege to feel that way… I would love not to spend an hour feminising my face every morning. Make-up is crucial to transition: it enables me to be seen how I see myself and how I want to be seen by society.”

In a recent article on the Boots No. 7 cosmetics range, Richard Hornsey notes how feminist scholars have described how political debates around make-up are often split between two analytical frameworks. Whereas one side argues that make-up paints women into patriarchal regimes of objectification, triviality and expense, the other celebrates make-up for encouraging self-expression and agency. Yet, as Charlie Craggs’ account suggests, both positions can fall short of reflecting lived experience. In describing the hour it takes her to get ready in the morning Craggs makes clear the work involved – the ‘aesthetic labour’ to use the terminology of Ana Elias et al – but Craggs also emphasises how make-up enables her self-expression.

Cosmetics have played a role in trans lives for a very long time, but in more recent history we can find evidence of how make-up was used to build community among individuals who transgressed gender boundaries in diverse ways. The Beaumont Society is the longest running support organisation for the transgender community. In 1993, the Society reworded their constitution with the aim of bringing together people who ‘cross-dress[ed]’ with ‘transsexuals’ to ‘reduce the emotional stress, eliminate the sense of guilt’ and ‘promote and assist… the study of gender role differences.’ In the same year, they launched a new Beaumont Magazine to encourage communication between members (available at the British Library). Focusing mostly on ‘cross-dressing’ and feminine gender expression, the magazine also provided space for the discussion of gender dysphoria, and printed occasional articles which explored trans masculinity and ‘third gender’ lives. It made space for readers to share photographs, send in letters and put questions to other readers: ‘You ask the questions… we give you an answer and invite you, the READER, to give us your wisdom. Send your solutions to us!’ (Volume 1, No. 4). Like mainstream women’s magazines of the period, the Beaumont Magazine utilised readers’ letters to help create a sense of community.

Make-up and beauty featured heavily on the ‘questions’ page and were integral to this formation of community. In the Summer Holiday 1993 edition (Volume 1, No.4), Cheryl wrote; ‘I always take care with my eye make-up. Then I ruin it by mis-managing my mascara brushes. Any pointers?’ She received a sympathetic answer lamenting the difficulty of the ‘acquired skill’ of make-up and encouragement to try false eyelashes: ‘The only problem is high temperatures, such as at a disco, when perspiration can unglue them. Better than having mascara running down your cheeks!’

Another reader Ann asked, ‘How do I stop my lipstick ‘bleeding’ along the outer line and looking smudgy?’ In the Christmas issue her question was answer by Davinia, who wrote: ‘This is how Estee Lauder suggest you do it in their handouts…’ before detailing a lengthy six step process. Make-up helped these individuals be seen as they wanted to be seen and build community through shared knowledge and experience.

Artefacts collected in Brighton Museum’s Museum of Transology exhibition illustrate that while some trans and non-binary people now learn about make-up through Youtube, certain cosmetic items continue to represent forms of community. A lipstick donated to the collection came with the explanatory tag attached: ‘This lipstick was from my wonderful sister who was the first family member to accept and support my transition.’ Sisterly support imbued this everyday object with an emotional significance.

Stories like these show how make-up is anything but trivial. At Made Up: Health and Beauty Secrets Past and Present – an event series organised as part of the Being Human Festival (14-23 November 2019) – we will be exploring the role of grooming in everyday lives in post-war Britain.

If you are in Colchester or the wider Essex area, join us for Beauty School Drop In on Saturday 16 November – a historical beauty salon where you can get your nails done by Charlie Craggs, hear historical talks, take part in craft activities, and share your own memories and photographs of past hair and make-up choices. Photographs and recordings collected at Beauty School Drop In will be shown as part of Faces: An Exhibition of Changing Essex Style on Saturday 23 November. This one-day pop-up exhibition will also host Glow Up – a zine-making workshop with artist Lu Williams of Grrrl Zine Fair.

Learning from a “Living Source” in Working with Historical Recipes: Reflections on the Burgundian Black Collaboratory

By Jessie Wei-Hsuan Chen


This week, we continue our series of cross-postings on a fascinating hands-on, collaborative research project into recipes for Burgundian Black, organized by Dr. Jenny Boulboullé. In today’s selection, we hear from Jessie Chen on her experiences of the project. This post is our second entry in the series, reproduced from Artechne, July 3rd, 2019. (Joshua Schlachet)


Burgundian Black Collaboratory

Between the 16th and 18th of January, I was invited to participate in the Burgundian Black Collaboratory.[1] For this workshop, experts from different fields joined forces to experiment with reconstructions of early modern black dyeing technologies based on a selection of historical recipes (Fig. 1).[2] The workshop is part of the research for a collaborative exhibition project that will be on view at Museum Hof van Busleyden in Mechelen later this year, and an edited-volume-in-planning on the subject of “Burgundian Black.” For now, I want to write about some thoughts on the method of learning from a “living source” using my own experience of the workshop.

Fig. 1. Experts from different fields experimenting with different recipes in our temporary lab, which was a greenhouse on the farm De Kreake in Húns in Friesland.

What is a “living source”?

In her article, Timea Tallian proposed three groups of living sources that can help fill the gaps in understanding historical recipes: experts, masters, and practitioners.[3] The definition of the three groups is more suggestive than hard-drawn. In general, “expert” refers to a person who conducts practical and/or scientific experimentation or reconstruction based on historical documentation. “Master” refers to a person who has acquired an art or craft through apprenticeship and continued to practice it for a long time. “Practitioner” refers to a person who has gained most knowledge from personal experience in making art/craft and self-motivated research into historical techniques.[4]

A simplified experience of working as an apprentice

During the Burgundian Black Collaboratory, I was in the same group as Jo Kirby-Atkinson, former Senior Scientific Officer at the National Gallery in London and co-author of the seminal book Natural Colorants for Dyeing and Lake Pigments.[5] Jo is, in every aspect of the term, an expert on natural colorants and materials, whereas I am a novice with no prior experience in working with natural dye and textile. While not strictly, the dynamic of my group resembles a historical workshop, with an expert/master showing the ropes to an apprentice. Our group was given three seventeenth-century recipes to decode, with two originally written in Dutch, but translated into English, and one in French.[6] All three recipes yielded rich black dyes (Fig. 2), even though we had to compress the multiple-day dyeing-processes into only a few hours.

Fig. 2. Top left: our equipment for the experiments; Top right: the different textiles we gathered before dyeing them black; Bottom left: in the middle of dyeing following the instructions of one of the Dutch recipes; Bottom right: final results of our experiments.

For three days, I followed Jo around, gathered and prepared the needed materials as she had instructed, and attentively listened to her explaining the reasons behind the decisions she made to follow or modify the recipes when dyeing our textile. Unlike many historians that start working with recipes by reading and interpreting the texts right away, I started by listening to and absorbing the knowledge of the expert/master.

In fact, this has always been how I learned historical techniques, or any artistic techniques. When I was in art school, manuals and how-to guides were always part of the assigned readings for classes, but I seldom consulted them. Instead, I observed what the professors did during demonstrations and tried to replicate the processes and results. For my first lesson in historical remaking, I learned an eighteenth-century metal-casting technique (Fig. 3) through the step-by-step explanations from an Amsterdam-based silversmith and conservator.[7] Similarly, I gained my knowledge in early modern printing (Fig. 4) by working alongside a master printer who learned the trade in a workshop. While historical recipes and instructions still play an important part in my research of these techniques, I do not usually read them until after I have some hands-on experiences.

Fig. 3. Left: removing the lion head ornament from the casting flask; Right: the cast and the original lion head ornament.

 

 Fig. 4. Two process photos of printing with a hand press.

Limitation or liberation?

How does learning from these experts affect my reading of historical recipes then? Does knowing the practical aspects of a technique help me understand the recipes better? Or does it prevent me from finding other possible interpretations of a recipe because I am conditioned by what the experts have shown me?

Upon reflection of the workshop, I noticed that my take on the original source is, indeed, shaped by Jo. When going through the recipes afterwards, my mind replayed the steps we took to dye our textile black. Interestingly, the recipes became so straight forward. In the imagined laboratory, my mind automatically filled in the gaps in the recipes with the decisions and measurements Jo made during the workshop. She has taken all the guess work out of interpreting the recipes, and what I have is a very cleaned-up, and perhaps all-too-easy, version of the processes.

However, I also noticed that I started to question some other things that are not necessarily directly related to the texts in the recipes we were testing, but to the broader historical contexts. For example, for one of the recipes we put linen and woolen materials in the same dye bath for the experiment. The linen came out more of a gray than black. Jo explained that in order for linen to get to the same level of blackness as wool, it would require a much longer time to mordant the fabric with alum. Historically and practically speaking, linen would not have been dyed with this particular recipe anyway because the cost of the overdyeing process (dyeing with multiple dye baths) would have been too expensive for the fabric. Such a recipe, thus, would have only been used for high quality material like wools and silks. These comments got me curious about the alum trade and the regulations of dyeing certain fabrics in the early modern period to which I have never paid attention before.

From novice to expert, eventually…

To answer my own questions, I think that gaining the hands-on skills from an expert/master is beneficial to prevent me from getting caught up with words and sentences as a novice; instead, I can focus on connecting the technique of investigation to its larger historical and social context. Learning from these experts also makes me become more aware of the oral knowledge transfer in a workshop in addition to written recipes. As I am only at the beginning of working with historical recipes, there will be more opportunities to interpret and experiment with recipes for different materials and techniques without the aid of an expert. Much like an apprentice who would become a master, I think that I will eventually find my own perspective on working with recipes.

Jenny was also part of our group; but due to her role as the organizer, she was much needed by other participants and thus I mostly worked with Jo on the hands-on aspect of the experiments during the workshop.
