Egyptian faience is a non-clay based ceramic composed of crushed quartz or sand, with small amounts of calcite lime and a mixture of alkalis, displaying surface vitrification due to the soda lime silica glaze often containing copper pigments to create a bright blue-green luster. [7]
A parting and contraction of the glaze on the surface of ceramic ware during drying or firing, resulting in unglazed areas bordered by coalesced glaze. May be caused by uneven glazing, excessive glaze thickness or a greasy substrate. [8] Crazing A glaze fault characterised by the cracking of fired glazes and due to high tensile stresses.
An important classification system for Egyptian pottery is the Vienna system, which was developed by Dorothea Arnold, Manfred Bietak, Janine Bourriau, Helen and Jean Jacquet, and Hans-Åke Nordström at a meeting in Vienna in 1980. Seriation of Egyptian pottery has proven useful for the relative chronology of ancient Egypt.
Frit. A frit is a ceramic composition that has been fused, quenched, and granulated.Frits form an important part of the batches used in compounding enamels and ceramic glazes; the purpose of this pre-fusion is to render any soluble and/or toxic components insoluble by causing them to combine with silica and other added oxides.

Egyptian faience is a ceramic material, made of quartz sand (or crushed quartz), small amounts of lime, and plant ash or natron. The ingredients were mixed together, glazed and fired to a hard shiny finish. Faience was widely used from the Predynastic Period until Islamic times for inlays and small objects, especially ushabtis.
The alkali of Syrian and Egyptian glass was soda ash (sodium carbonate), which can be extracted from the ashes of many plants, notably halophile seashore plants like saltwort. The latest vessels were 'core-formed', produced by winding a ductile rope of glass around a shaped core of sand and clay over a metal rod, then fusing it by reheating it ...
Maram, an Egyptian woman in her mid-30s, told me in an interview for my book, “I grew up believing kohl was a traditional Egyptian practice. When I started using kohl as a teenager, I thought it ...
Blue faience saucer and stand, New Kingdom (1400–1325 BC) Egyptian blue is closely related to the other vitreous materials produced by the ancient Egyptians, namely glass and Egyptian faience, and it is possible that the Egyptians did not employ separate terms to distinguish the three products from one another.
