Earthenware is glazed or unglazed nonvitreous pottery [2] that has normally been fired below 1,200 °C (2,190 °F). [3] Basic earthenware, often called terracotta , absorbs liquids such as water. However, earthenware can be made impervious to liquids by coating it with a ceramic glaze , and such a process is used for the great majority of ...
Underglaze is a method of decorating pottery in which painted decoration is applied to the surface before it is covered with a transparent ceramic glaze and fired in a kiln.

[ 15 ] [ 16 ] Better wood kilns and gas kilns can reach temperatures of between 900 and 1000C, which is not quite yet high-fire, but allows the use of more types of low lead or ...
