high-temperature coloursThe pigments which, when applied to earthenware, could withstand the high temperature required to unite them with a tin glaze and fuse it to the surface of the clay. The high-temperature colours are cobalt, copper, manganese, antimony and iron, yielding respectively blue, green, purple, yellow and red. Most tin-glazed earthenware was decorated with these colours until the 18th century when enamel colours were developed. |
