Ceramic Frits are vitreous compounds that have been melted, and then rapidly cooled.
The compounds are insoluble in water, and when added to glaze, the glaze will be insoluble.
Frits allow even some hazardous materials to become safer components in fired glazes.
Frits also allow glazes to be fired at low temperatures, and encourage a more consistent result.
Frits can be used as a primary of auxiliary flux.
Frit 3110 is a soft sodium borosilicate frit for glazes.
It can help reduce the feldspar content in glazes, allowing you to increase kaolin and improve slurry properties.
Although this frit is chemically similar to a feldspar, it has low alumina and calcium oxide.
Frit 3110 can be used with Frit 3403 for bright and semi-matte wall tile glazes.The fusion temperature is 1490 F.
