Chemicals » Ferro Frits
Frits are glaze materials which have been melted, cooled, and ground into a powder which is then added to a glaze formula for the purpose of rendering insoluble any soluble materials. The use of frits also allows for the incorporation of certain raw materials in the creation of glazes. Some materials, which alone could be hazardous, become safer components in a fired glaze. Recognized benefits of frits include the ability to fire at a lower temperature, the creation of a homogeneous quality, and a more consistent result.

| Ferro Frit 3124 This borosilicate frit is high in calcium which means it will affect browns and iron oxide colours. This frit has a chemistry similar to an alumina addition to Frit 3134. It is intended for use in partially fritted glazes for wall tile and pottery dinnerware glazes in the cone 3-5 range.
