The main types of decoration applied on glaze in earthenware products are: Lining and Banding, including Gold Lining, Stamping, Spraying, Lithographing and Silk Screening. In some cases most expensive types of decoration such as ground laying and acid gold edge are also used.
The decorating process is similar to Under-Glaze operations. Gold lining and banding can be done by hand or by machine. The machine decoration gives more consistent results. Nowadays more automatic machines are available which will apply more than one line at a time. Wares like flatware are kept in a wheel and rotated and simultaneously the liquid gold is applied.
Figured rollers can also be used to apply pattern bands on liquid gold. Patterned bands can also be applied to the edges of cups. Stamping can be done with rubber stamps and rubber rollers. Colours can also be applied by dusting after first stamping on the pattern in a sticky lacquer. The Murray-Curvex machine can also be used for On-Glaze decoration.
Lithography is an important method of decoration and is a widely used decorative process in all Earthenware factories. Ready made litho papers are available in markets which can be used.
