Steps to Create a Fish-Shaped Predynastic Ancient Egyptian Palette

This is an excerpt from my upcoming paper discussing the manufacture and use of Predynastic Ancient Egyptian palettes, highlighting the various steps which are required to create a fish-shaped (pisciform) palette. The replica was made from slate rather than siltstone/greywacke, as the material was easier for me to obtain. The steps are essentially the same but as slate is softer (Moh 3-4 vs Moh 6-7) it would take longer to create out of siltstone/greywacke and be potentially more abrasive to the tools.
