Instructions

This clear, stoneware-temperature glaze fires to 2336°F (1280°C). The recipe comes from the Guldagergaard International Ceramic Research Center in Skælskør, Denmark. I apply this clear glaze by spraying to a thickness of approximately 1 mm over cobalt oxide, which I purchased in Jingdezhen, China, while traveling.
