Ibn al-Rassam (literally Son of the Draftsman) was an Egyptian Muslim alchemist and tile maker and mosaic designer, who flourished during the Mamluk Bahri dynasty (1250–1382). [1]
Ibn Rassam is widely known to have invented the techniques through which he obtained copper from varieties of malachite. He also ascertained indigo by heating various substances. [2] He was a colleague of the chemist, Abul Ashba ibn Tammam (d.1361).
