The body of green-glazed pottery ceramics was made of clay, coated with a layer of glaze, and fired at a temperature of 800 degrees Celsius.
Green-glazed pottery is a type of lead-glazed earthenware (Chinese: 鉛釉陶器): lead oxide was the principal flux in the glaze, often mixed with quartz in the proportion of 3:1.
[1] Due to the low firing temperature, the bodies are earthenware, and the glaze often only applied to parts of the objects, which are fragile and have high water absorption.
For these reasons, the objects are only known as grave goods from burials, and examples used in everyday life have not been found.
[5] Green-glazed pottery was to be followed by Sancai polychrome glazes, generally including the same green, from the 7th century during the Tang period.
