tableware made of egyptian faience, glazed in vivid blue, turquoise or green, continued to be manufactured in egypt throughout the roman period, and the shapes of some of these faience vessels in the 1st century bc and 1st century ad were directly influenced by arretine ware. very elaborate, decorated polychrome faience vessels were also produced. egyptian faience, frit or 'glazed composition', as it is often termed by egyptologists, has rather more in common technically with glass manufacture than with earthenware, since it is a non-clay ceramic material.
