| - Frit is a ceramic composition that has been fused in a special fusing oven, quenched to form a glass, 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. However not all glass that is fused, and quenched in water is frit, as this method of cooling down very hot glass is widely used in glass manufacture.

| - Frit is a ceramic composition that has been fused in a special fusing oven, quenched to form a glass, 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. However not all glass that is fused, and quenched in water is frit, as this method of cooling down very hot glass is widely used in glass manufacture. The origin of the word "frit" dates back to 1662 according to the OED as " a calcinated mixture of sand and fluxes ready to be melted in a crucible to make glass". Nowadays this is more commonly called "glass batch", the unheated raw materials. In antiquity, frit could be crushed to make pigments or shaped to create objects. It may also have served as an intermediate material in the manufacture of raw glass. The definition of frit tends to be variable and has proved a thorny issue for scholars. In recent centuries, frits have taken on a number of roles, such as biomaterials and additives to microwave dielectric ceramics. Frit in the form of alumino-silicate can be used in glaze free continuous casting refractories.
