لوحة نارمر
The Narmer Palette is a , shield-shaped, ceremonial palette, carved from a single piece of flat, soft dark gray-green siltstone. The stone has often been wrongly identified, in the past, as being slate or schist. Slate is layered and prone to flaking, and schist is a metamorphic rock containing large, randomly distributed mineral grains. Both are unlike the finely grained, hard, flake-resistant siltstone, whose source is from a well-attested quarry that has been used since pre-dynastic times at Wadi Hammamat. This material was used extensively during the pre-dynastic period for creating such palettes and also was used as a source for Old Kingdom statuary. A statue of the 2nd dynasty pharaoh Khasekhemwy, found in the same complex as the Narmer Palette at Hierakonpolis, also was made of this material.
