At the same time in China, green-glazed pottery dating back to the Han period (25–220 AD) gave rise eventually to the sancai ('three-color') Tang dynasty ceramics, where the white clay body was coated with coloured glazes and fired at a temperature of 800 degrees C. Lead oxide was the principal flux in the glaze.
Lead glazes, plain or coloured, are glossy and transparent after firing, which need only about 800 °C (1,470 °F). They have been used for about 2,000 years in China e.g. sancai, around the Mediterranean, and in Europe e.g. Victorian majolica. Salt-glaze, mostly European stoneware. It uses ordinary salt.
