Ice crystal glaze

Experiment

Normally, ceramic crystal glazes form small or large flat crystals on a surface, as shown on the frame area of some samples. In this project, the aim was to make three dimensional crystals appear in a glaze layer.

Process & Production

On small square bisque stoneware sample pieces, a big lump of crystal glaze powder is added onto square cavities in the middle. Please look up the glaze recipe below. The glaze powder is not mixed with water. Underneath the crystal glaze is a layer of engobe in various colours, mainly from cobalt oxide, to make an impression of an ice blue winter pond. Due to the high material tension in the thick layer of glaze, this glass-like layer will crack, like ice on a lake.
