C627 Astral Blue.
The Ceramic Shop's Cone 6 Professional Series Astral Blue Glaze is an opaque glossy glaze that shows off its range of light to medium blue hues. It is a durable glaze that looks great when applied with other glazes. We recommend applying by dipping or spraying, but brushing will also work.
These Cone 6 glazes have been used in studios and schools for over ten years. All glazes are lead free, non-toxic and conform to ASTDM 4236 standards.
