Continuing the work of an exhibition at the Folger Shakespeare Library from last year, this presentation places Robert Boyle’s experiment “Of turning the Blew of Violets into a Red by Acid Salts, and to a Green by Alcalizate and the use of it for Investigating the Nature of Salts” in the context of the extensive archive of women’s medical receipts. In the experiment Boyle used the common medicine “Syrup of Violets” and its chemical sensitivity of turning color when introduced to acids and bases in developing an early pH indicator. When viewed next to the hundreds of relevant medical receipts, we discover that Boyle’s experiment builds on knowledge collectively held by women and men, including Alathea Talbot and Hugh Plat, in the making of the medicine.
