Frits are important components of most ceramic glazes. A frit is a type of ceramic glass that predominantly consists of silica, diboron trioxide, and soda. This combination of raw materials are industrially melted and rapidly cooled, making them insoluble.
According to the OED, the origin of the word frit dates back to 1662 and is a calcinated mixture of sand and fluxes ready to be melted in a crucible to make glass. Nowadays, the unheated raw materials of glass making are more commonly called glass batch.nother type of frit can be used as a biomaterial, which is a material made to become a part of, or to come into intimate contact with, one or more living organisms. Molten soda-lime-silica glass can be poured into water to obtain a frit, which is then ground to a powder.
