Cone 05 - Cone 10
The Velvet Underglazes produced by Amaco are some of the finest available. Bright and semi translucent, the velvet underglazes come in over fifty colors that have a tolerant firing range from Cone 05 - Cone 10. When dipped or coated with a clear glaze they are dinnerware safe. Try The Ceramic Shop's Cone 06 Real Clear, Cone 6 Classic Clear or the Amaco Cone 5 HF9 Zinc Free Clear to express the intensity of the underglaze color. We also have a Sepctrum Clear that fires to Cone 10, available in gallon or pint size. Note: Some of the underglazes, like 318, 320, 371 and 375, will change color when fired above Cone 5, best to do test tiles to achieve best results.
