Stone palettes were used for grinding eye paint worn for cosmetic purposes and to protect against sun glare and eye infections. There were two types: green, made from malachite (copper ore), and black, made from galena (lead ore). As funerary items, these ores may have had a deep significance for the deceased as symbols of regeneration and rebirth: the rich soil of the banks of the Nile (black), and the lush vegetation it sustained (green).
