An impressive handwritten codex at the National Library of Israel embodies the intricacies and peculiarities of crafting, reading, and transmitting practical knowledge in early modern Jewish contexts. The volume, known today as manuscript NLI 8º 1070, was likely produced in the 1730s somewhere in the Polish territories. A variety of local Polish-Ashkenazi traditions are well attested throughout the codex: vernacular and elite, theoretical and practical, of Jewish and Christian provenance, and transmitted mainly in Hebrew and Yiddish, but with elements of Latin, German, Polish, Russian, and Ruthenian.
In Elizabethan London, one of the more surprising things a wealthy owner of a beautifully illustrated folio volume could do was to take a sharp knife and cut it to pieces. John Blagrave’s 1585 Mathematical Jewel, in fact, demands nothing less. This work, which introduced an elaborate instrument of Blagrave’s design for performing astronomical calculations, included woodcuts that were specifically provided in order to be cut out and used as surrogates for the brass original:
get very fine pastboord made of purpose, and then spred your paste very fine thereon, & quickly laying on this picture & clappe it streight into a presse before it bee thorowe wette with the paste (fol. ¶6v)
On November 4, 1646, Sir Theodore de Mayerne (1573–1655), first physician to Charles I and the English Aristocracy, decided to spend his day away from his demanding patients and to devote his attention to the vibrant world of colors. He took a good handful of bilberries and carefully inspected the color of their peel and pulp. He then cooked them following a recipe for making a “very beautiful and very oriental” colorant for writing and limning. The recipe he followed has survived as part of an extensive manuscript collection dated to the first half of the seventeenth century.
In premodern China, the population was roughly divided according to professions into four groups: literati, farmers, artisans, and merchants. During this period, artisanal knowledge was mainly transmitted in person. Most Chinese artisans were not as literate as their European counterparts, if literate at all, and written texts played a minor role in the transmission of their specialized knowledge. The master of a workshop taught the apprentices how to perform bodily actions by working alongside them and only transmitted written knowledge with brief and codified texts. Sometimes craft recipes were not even written down; they were memorized by masters and transferred verbally to designated successors in the craft. 
When the alchemist-priest Antonio Neri published his L’Arte Vetraria in 1612, the universe of codified knowledge could finally include a major work entirely devoted to glassmaking. Although the Florentine friar was by no means the first to provide instructions on how to make glass (recipe texts are known from the second millennium BCE), never before had the effort been so comprehensive and successful.
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.” 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.
In this article, Pamela Smith links the tacit and explicit knowledge of artisans in an innovative way. See also Jonathan Sheehan’s interesting review of Smith’s related book, The Body of the Artisan: Art and Experience in the Scientific Revolution (Chicago, IL: University of Chicago Press, 2004).
