Remarks
Carbon ink was one of the four main types found in the 11th-century Genizah corpus (p. xxvii). For the Babylonian community, it was used alongside other types on leather supports (p. xxviii). The Talmud, while not providing a recipe, discusses the properties of carbon ink and its use in creating mixed inks for better fixation (p. xxii, note 13).
