As October draws to a close, we feature yet another exciting article from our ongoing series of cross-postings on the hands-on, collaborative research project into recipes for Burgundian Black, organized by Dr. Jenny Boulboullé. Today, Sharifa Lookman provides another fascinating peek into the inner workings of the project (Joshua Schlachet)
For the pre-modern artist, color was anything but random. As both concept and product, it wore many masks: the bearer of symbolic significance, an agent of trade, and a protagonist in histories of politics, economy, and geography. In material, it was the hard-earned product of natural ingredients and arcane, even alchemical processes. Researchers in the Faculty of Design Sciences and the working group ROOHTS (Research on the Origin of Historical Techniques) at the University of Antwerp have returned to historical recipes to investigate these aspects of color. From July 1-5, in collaboration with the ARTECHNE ERC research group at the University of Utrecht, researchers took up the following question: how did pre-modern colorists perceive, manufacture, and master the color black?
The intensive, five-day summer school, “Burgundian Blacks,” brought together artists, scholars, and scientists of diverse backgrounds to investigate black color technologies of multiple media, working from the production of black textile dyes (the focus of a January workshop, the Burgundian Black Collaboratory) and moving into adjacent practices used to produce black inks and paints in and around the historic region of Burgundy. Each day consisted of a theoretical component and a practical one: classes moved back and forth between the lecture hall, with studies on historical contexts, and the laboratory, where recipes were tested through experimental reconstructions, or (re)enactments.
The setting—a university conservation laboratory—was decidedly ahistorical and acknowledged the inherent limits of reconstruction: small sample sizes and anachronistic instruments, for starters. And yet, when all thirteen of the participants and a handful of instructors were in the lab together, we more or less simulated an active ‘workshop,’ complete with masters and apprentices, back-and-forth shop talk, and bustling bodies (Fig. 1). As a participant, I found that the summer school’s give-and-take between the written word and re-enactment emphasized two fundamental ideas in the study of color technologies: the mutability of language in interpreting recipes and the intellectual merit of touch and sensation in reconstructing them; in other words, the valuable cross-fertilization of both mind and body in materiality studies.[i]
Mind/Language:
In considering early modern writings on color, twenty-first century scholars must first be acquainted with an author’s vocabulary, biases, and technical ‘know-how.’ This was the case in our workshop reconstruction of “Noir de Flandres” (Black of Flanders), a seventeenth-century French recipe for a madder and woad-based dye. Here the compiler of the recipe added in his own hand, “And you will have a perfect and durable black” (Fig. 2).[ii] What, according to our writer, is a ‘perfect black,’ and how did it relate to other early modern colors? Over the course of our two-day dye session we produced a number of dyed textiles, many in various shades of black and others not black at all (Fig. 3). Were any of them ‘perfect?’ We often struggled with terms to describe this range, using words such as ‘fresh,’ ‘saturated,’ or ‘opaque.’ But are these the terms an early modern colorist would use? Our author does tell us that, in addition to being ‘perfect,’ the Noir de Flandres is also ‘durable,’ implying that, even in the moment of its making, it was important that the color last for posterity.
Knowledge of materials, processes, and techniques was also gleaned from sources that were not written down, namely ‘shop talk,’ a kind of knowledge circulated within and across artist workshops. Though the dye recipes we tested ranged in time period (1350-1670) and geography, they often shared ingredients. By analyzing the presence and absence of certain ingredients in black dye recipes, scholars, such as Natalia Ortega-Saez of the University of Antwerp, have classified these recipes into three main groups.[iii] Based on these, a twenty-first century reader can effectively ‘fill in the gaps’ when information in the original transcription of one particular recipe is missing or unclear. Likely, a contemporary would have done just that, having considered particular instructions to be common knowledge. We might think back to the Italian artist and writer Giorgio Vasari who, describing fourteenth-century artist Cennino Cennini’s treatise on painting, wrote, “[Cennini] was anxious to know the peculiarities of colors … and gave much advice which I need not expand upon, since all these matters, which he then considered very great secrets, are now universally known.”[iv] By the sixteenth century certain materials and their properties must have been widely known across Europe, and the disappearance of these procedures in writing suggests that this information was not forgotten, but instead circulated verbally, just as we shared and transmitted knowledge orally in the laboratory.
Body:
Where our dye reconstructions were much more ‘experimental,’ some recipes being deciphered and tested for the very first time, our pigment recipes had comparatively fewer unknowns. Instead, we were encouraged to consider the appearance, smell, and feel of our materials as we progressed through the recipes. Simply put, we shifted away from the written and spoken word and towards the sensory experience of color production. We began by roasting our raw ingredients—primarily animal bones and fruit pits—in crucibles in an open flame (Fig. 4). The goal here was to char the materials just until they turned black; too long on the flame risks turning the bones white, the base for another color, ‘bone-white.’
The body took centerstage as we began grinding our pigments. Organic materials, like fruit stones and plant matter, broke down in mere minutes, but sheep and bovine bones were significantly denser and more difficult, some requiring twenty to thirty minutes of continuous grinding. To achieve the kind of fine powder necessary for high-quality pigments, one clearly needed strength and dexterity as well as a cultivated sensitivity to natural materials. Without time specifications in our recipes, we ground our pigments until they felt finely powdered, and mulled them with water until we could no longer feel or hear granules sliding between the glass (Fig. 5). Sensory indicators—touch, smell, and sight—developed into an acquired “skilled vision” and “expert touch” akin to shop talk, one that filled gaps in reasoning.[v]
We considered these ideas even further by applying the pigments to paper: how did the paint feel when applied? What was its texture? Translucency? Facture? Here the term ‘body’ can be dually defined. In addition to referring to the body of the maker, it also suggests the ‘body’ of a color, as Jenny Boulboullé of the University of Utrecht has observed.[vi] The coloristic effects, success, and ‘body’ of our black pigments were not only dependent on its raw material and how we processed it, but also the type of binding medium used; depending on this, a color’s transparency, density, and quality differed considerably (Fig. 6). Because we used only water and gum arabic as binders, I couldn’t help but wonder how, precisely, the choice of binder can modulate the color black. In other words, to quote Ann-Sophie Lehmann, in mixing and applying pigment, what is the “matter of the medium?”[vii]
Re-enactments of historical techniques bring to the surface ideas that are often latent in strictly theoretical approaches to technique and materiality. By investigating recipes for pre-modern black, we engage with color as both technique and concept, as the cross-geographical product of nature and artistic experimentalism, and, above all, as an area of study that has increasingly come to move across disciplines and scholarly domains.
