Lead Free Glazes & Underglazes
All AMACO glazes currently in production are labeled to indicate their suitability for use on food or drink containers. Most AMACO Glazes are certified dinnerware-safe through independent laboratory testing in order to meet FDA Guidelines. When AMACO dinnerware-safe glazes, such as LG-10 Clear Transparent, are used over other AMACO underglazes on pottery, such containers also become dinnerware-safe.
All AMACO® glaze labeling features either the “AP” (Non-Toxic) seal or the “CL” (cautions required) seal of the Art and Creative Materials Institute, Inc. (ACMI). These seals are your assurance that the product was evaluated by an independent toxicologist and labeled according to ASTM D-4236/LHAMA—the federal standard for safe labeling of art materials.
From our extremely popular Gloss Glazes (LG Series) to our versatile Velvet Underglazes (V Series), there's a color for any artistic style.
