Fused Silica Glazes

Using Ian Currie’s grid method, we tested glazes with high percentages of kaolin, silica and flux. Excess silica in a glaze can create a sugary crusty surface. When mixed thick and sprayed onto a surface repeatedly, these silica glazes can build on a surface. Enough flux was needed to solidify the surface but too much would cause the surface to melt and flatten, hence the name fused silica glaze.

Fused Silica: Frit & Nepheline Syenite

We tested various fused silica recipes, in this section they are predominantly mixed with Frit or Nepheline Syenite. They are then sprayed (in many layers) onto the bisque surface with a spray gun.
