Material based on silica and other minerals that forms the DNA of all ceramic glazes.

OPPURE: Material based on silica and other minerals which forms the base of all glazes used in ceramic production.

Frits are produced by merging raw materials in melting furnaces at temperatures of about 1000-1450 °C. The molten mixture undergoes a sudden cooling with the help of water and special cylinders that produce glass flakes about a millimetre thick. The frit reduced in flakes is then ground in special dry mills to obtain electrostatic powder, or dissolved in a water suspension to get glaze in the liquid state.

The formulation of the frit affects and defines the chemical composition and therefore the physical, chemical and mechanical features of the glaze.
