Wadi Hammamat
Cosmetic palettes are archaeological artifacts, originally used in predynastic Egypt to grind and apply ingredients for facial or body cosmetics. The decorative palettes of the late 4th millennium BCE appear to have lost this function and became commemorative, ornamental, and possibly ceremonial. They were made almost exclusively out of siltstone with a few exceptions. The siltstone originated from quarries in the Wadi Hammamat.
