Egyptian faience is a sintered-quartz ceramic displaying surface vitrification which creates a bright lustre of various colours, with blue-green being the most common.
Egyptian faience is a low-fire mixture of ceramic materials containing clay, sand, colorants, frits, and soluble salts. These salts effervesce to the surface along with water as the paste slowly dries, forming crystals, which create a self-glazing clay-glaze hybrid once fired, which was invented around 2500 BC.
