Used as a binder and to lower the melting point. Lime (Calcite): Added to stabilize the mixture.

Faience is an ancient ceramic material that is notably non-clay based, composed primarily of crushed quartz or sand combined with small amounts of calcite, lime, and alkalis. Often described as the world's first "high-tech" material, its characteristic bright blue-green luster is achieved through surface vitrification during firing.

Below is an overview paper on the technology and cultural significance of faience. faience

Ancient artisans utilized three primary techniques to achieve a glazed finish:

Faience remains a testament to ancient chemical engineering. Its unique properties—situated somewhere between a ceramic and a glass—allowed ancient civilizations to mass-produce objects that were both aesthetically striking and spiritually significant. Egyptian Faience: Technology and Production Used as a binder and to lower the melting point

Water-soluble salts migrate to the surface as the object dries, forming a crust that melts into a glaze during firing.

A glaze slurry is directly painted onto or dipped over the pre-formed core. IV. Cultural and Symbolic Significance Often described as the world's first "high-tech" material,

Faience, particularly the variety famously produced in Ancient Egypt, represents a significant milestone in human material science. Unlike traditional ceramics made from clay, faience is an artificial, glass-like substance. Its production peaked during the New Kingdom period (1570–1070 B.C.), where it was used to create everything from tiny amulets to large architectural tiles. The "body" or core of faience consists of:
