This group includes glass and ceramics painters and decorators not elsewhere classified, for example those who coat ware or parts of ware with oil and dust oiled surface with powder colour; draw lines on ceramic ware to guide other workers in applying coloured glaze and other decorations; polish gold-decorated ware by scouring with fine sand and finishing it with agate or bloodstone; or tend machines conveying ware through glaze sprays, dipping troughs and drying rooms.
