Frit - 3134 (Calcium Borate Frit - Low Alumina)
- Frit 3134 consists of sodium, calcium and boron and is typically used in both transparent and opaque glazes. It is often used for earthenware glazes, but it can be used in small percentages in stoneware glazes, as well.
- Ceramic Frits are important components of most ceramic glazes and predominantly consist of silica, diboron trioxide, and soda. Frits are vitreous compounds, are insoluble in water and are created by melting and then rapidly cooling controlled blends of raw materials. Because of their various applications, there are numerous types of Frits, each with specific uses. Despite the diversity, however, manufactured frits typically all contain more than one kind of flux and are stabilized with alumina and silica. This causes the frits to be more reliable when using to consistently reproduce glazes.
