A term used by Egyptologists for a type of white, semi-transparent or translucent, stone used in statuary, vases, sarcophagi, and architecture. It is a form of limestone (calcium carbonate), sometimes described as travertine. It was used increasingly from the Early Dynastic period for funerary vessels as well as statuary and altars. Alabaster is found in Middle Egypt, a main source being Hatnub, southeast of el-Amarna. The sarcophagi of Seti I (British Museum) is a fine example. An alabaster (also alabastron or alabastrum) is also the name of a small vase or jar for precious perfumes or oils made of this material. It was often globular with a narrow mouth and often without handles.
