Siliceous sandstone is a coarse- to fine-grained hard compact sandstone in which the cementing agent is precipitated quartz. It is often call quartzite by Egyptologists. There are two main areas in which siliceous sandstone was quarried by the ancient Egyptians, these are at Gebel Ahmar near Cairo, and on the west bank of the Nile opposite Aswan (see map). These sandstones vary considerably in both colour and texture. Colour maybe be light grey, yellowish, or various shades of red and brown. The grain size can range from fine-grained to coarse-grained, sometimes pebbly, and conglomerates are also sometimes observed. Photos of polished rock slabs obtained from various siliceous sandstone quarry sites used by the ancient Egyptians can be seen at the Ancient Egyptian Quarries website sections #1 and 3.
As a building material it was not used extensively, when used it was as lining of burial chambers and as thresholds of doorways. However, it was employed extensively for other purposes, for example sarcophagi and statues usually of the yellowish brown variety during the Old Kingdom to New Kingdom periods (Lucas and Harris, 1962).
