TP1 Coal Black Pint
TP-1 Coal Black is an opaque, slick obsidian glaze that boasts a glossy, smooth surface after firing. 100% mixable and true to their unfired color, the Teachers Palette glazes are a must-have for any classroom or studio. Also try using using Cotton (TP-11) as a base glaze and, using any of the other Teacher's Palette colors, brush on colorful designs and patterns reminiscent of majolica ware.
Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.
