This borosilicate frit is high in calcium. It melts are very low temperatures and among the most useful of all common frit's because of its glaze-like balanced chemistry.
Its stated intention is a calcium boron source for partially fritted glazes for wall tile and pottery, also in lead bisilicate dinnerware glazes in the cone 3-5 range. However, within pottery circles, like frit 3195 this frit is almost a complete glaze at low temperatures (requiring only a 10-20% addition of kaolin to suspend it).

A frit is a type of ceramic glass. It is a combination of materials which are melted together to render them insoluble and resistant to acid attack. They are therefore a means of introducing certain materials into a glaze which would otherwise be toxic. Frits can be used alone as low temperature glazes e.g. Raku and Majolica, but generally they form the basis of a glaze recipe.
LEAD FRITS Glazes based on lead frits produce a shiny, durable finish and give brightness and clarity of colour when used in conjunction with oxides, stains, slips etc. While they can be used on all earthenware clays, they are particularly suited for red clay.
BORAX FRITS Borax frits are often used in the production of earthenware glazes when a lead free frit is required. Slight milkiness, especially at low temps, may be evident over red clays and the colour response with oxides etc. is not usually as vivid as with lead frits.
ALKALINE FRITS Similar to borax frits, alkaline frits are noted for their high soda and potash content. The colour response from copper and manganese is turquoise and purple/brown respectively - typical of this type of frit. Alkaline frits have a high expansion rate which makes them a suitable base for crackle glazes.
