Majolica decoration

A decoration that is painted with under-glaze colors on top of an unfired opaque glaze is referred to as a Majolica decoration. The term “Majolica” originated many hundreds of years ago. During those early centuries most of the available clay was of a dark color which made decorating with brilliant colors difficult. Gradually the eastern potters learned that tin added to a transparent glaze would render it opaque, but tin was scarce.

It is still used widely as a means of decorating ceramics.

Although today we are fortunate in having a wide selection of white clay bodies to choose from, thus eliminating the necessity of resorting to Majolica as the only means of decorating with bright colors, Majolica decoration possesses a charm that makes it attractive to modern-day ceramists.

Painting over a coat of unfired glaze is difficult, so give the glazed piece a light coat of gum tragacanth before attempting further decorating. Do not use a pencil to sketch the design on the piece because the point is likely to mar the glaze. Instead, brush the design on with diluted India ink or vegetable dye which will burn out completely during the firing and will, in addition, provide Continue reading
