Preparation Steps

Original Recipe Text

Animal hides were subjected to tanning (madbugh) to produce writing parchment. 'Al-Raq' was processed to be thin, soft, and suitable for folding into codices (p. 106). 'Al-Adim' refers to red-tanned skin, famously used for early scriptural records (p. 107). 'Al-Qadim' is white-tanned skin, described as high-quality white sheets (p. 108). 'Vellum' is specifically identified as skin sourced from unborn animals (p. 107).

Evidence

Remarks

The text categorizes writing skins into four main types based on their tanning and color: Raq (general parchment), Adim (red skin), Qadim (white skin), and Riqa' (scraps). These materials were the standard supports for Islamic manuscripts before the transition to paper (p. 106-108).
