Ink and Pigments:Charcoal and soot were used to form black lettering on papyrus paper in Ancient Egypt. The Egyptians burned oil or wood, then crushed the resultant residue and mixing it with water. believe plant gums from the acacia tree family served to bind the ink properly to the paper. Other materials used for pigment include iron oxide, malachite and yellow ochre. Arsenic-based pigments such as realgar and orpiment were used to depict reds and yellows but faded with light exposure.
