Ceramic Pigments and Stains

We color ceramics using inorganic pigments and stains that are relatively insoluble in the ceramic they are coloring they should also be unaffected chemically and physically. This is not the same approach used for glass. 

700-900 Molten leaded/unleaded borosilicate glass Enamel or overglaze colors Tableware, tile decoration 

900-1000 Molten lead/unleaded borosilicate or alkali borosilicate glasses Low-temperature glaze stains, underglaze colors, colored pellets and granules Tableware, wall and floor tiles 

950-1200 Siliceous bodies Body stains, brick surface colorants, colored pellets and granules Tableware, floor tiles, fancies, bricks
