Frit

What is Frit? The mixture of silica and fluxes which is fused at high temperature to make glass. A frit is a type of ceramic glass that predominantly consists of silica, di boron trioxide and soda. This combination of raw materials are industrially melted and rapidly cooled. Frits form an important part of the batches used in compounding enamels and ceramic glazes. Not all glasses that is fused and quenched in water is frit, as this method of cooling down very hot glass is widely used in glass manufacture. What are the Classifications? Opaque Frit: It has lower or higher coefficient of thermal expansion, water anti- penetration ability, wide firing range, low softening point, resist to crazing. Transparent Frit: Excellent gloss & color development frit, often used in single fast firing wall and floor tiles, High Transparently glossy glaze suitable for rustic or homogeneous tiles. How does a Ceramic Frit make? Ceramic frits are obtained by fusing raw materials in a melting kiln at higher temperature. The melt is cooled quickly, either by quenching in water which transforms it into a fragmented solid that is practically insoluble in water. What are the Uses in ceramics? Because of their various applications, there are numerous types of frits, each with specific uses. Despite the diversity, manufactured frits typically all contain more than one kind of flux (for melting) and are stabilized with alumina and silica. This causes the frits to be more reliable in consistently reproducing glazes
