Basra: Lead (II) Oxide Makers
In his Aḥsan al-taqāsīm fi maʿrifat al-aqālīm, al-Muqaddasi (d. 991) mentioned that al-murdāsīnj was made in Basra. Al-murdāsīnj (i.e. lead [II] oxide) is an Arabized word from Persian, meaning ‘malignant stone.’ This is a yellow substance that can be employed in the manufacture of glass and glazes for ceramics. See also: Verdigris Maker; Cinnabar Maker; Potter; Glass Worker.
