Anotations

Scope note:

A form of porcelain decoration that combines underglaze blue outlines with filled-in overglaze enamel colors. The technique was difficult and required two firings: the first outline is painted in underglaze blue, then fired at a high temperature. The outlines were then coloured in with red, yellow, green and aubergine overglaze and the object was fired again at a lower temperature.
