Silica, Flint Size:22.68 kg Zirconium Silicate

Zirconium Silicate

This additive reduces the vitrification temperature required for a body to mature

Pyrophyllite is a hydrated aluminum silicate material and shares many physical properties with talc

but when combined with the typical oxides in a glaze (especially boron) it readily enters the melt

Since it is a good source of Na2O it is very commonly found in glaze recipes all temperatures

Silica, Flint Size:22.68 kg Zirconium SilicateSilica is one of the cornerstone materials of glaze and clay body formulation. Although this mineral is present in many different ceramic materials (from feldspars to bentonite to sand, for example), this silica is a pure version in a 200 mesh particle size. As for silica's function in clay and glazes, it provides the melting, or glass forming agents in a clay body that allow the material to fuse together. Silica has a fairly high melting point, so it
