Sax True Flow Carnivale Colorburst Glaze’s opacity is dependent on the number of applications and is ideal for one-of-a-kind pieces since every application and every firing will produce different results. Glaze may be a different color during application and will change to desired look after required firing in a kiln.Creates multi-colored patterns as well as designs when fired. Create unique dramatic effects by combining other glazes of a similar firing range. Base glaze fades, crystals melt and will leave a clear halo when fired at Cone 6. Freeze/Thaw stable. Not dinnerware safe due to surface characteristics.
