Exploring the possibility of low temperature glazing in faience from the Djoser Step Pyramid through compositional analysis
Egyptian faience, a glazed, non-clay based ceramic material, is found throughout Egypt in a time range pre-dating the Predynastic Period (5500 - 3100 BCE) and extending well beyond the Roman Period (30 BCE - 641 CE). One of the most monumental feats of faience production and one of the first …
