Cobalt Blue Glaze Crystals (1oz) by Spectrum

 The glaze crystals are all lead free and dinnerware safe. They are suitable for a large range of temperatures, from cone 06 to cone 10.

The higher they are fired the more they will spread out and move around. Crystals can best be applied to the final coat of a glaze while it is still wet or mixed into the final coat of the glaze and brushed on with the glaze.
