Underglazes

Our underglazes, crayons and engobes for Earthenware and Stoneware are ready mixed for brushing and need to be covered with a fitting clear glaze to be food safe. At stoneware temperatures there can be structural and color changes. Recommended as a clear glaze for earthenware: NTBR, EM-2134. For stoneware: HF-9, MS-100, SW-004, STG-1200, STG-1100, MS-29.
