Overglaze colours in enamel were used from about 1768.

Overglaze colors are low-temperature glazes that give ceramics a more decorative, glassy look.

There's a continuously changing display of one-off works by Clementina van der Walt and other artists here, as well as a full selection of Clementina's distinctive tableware, hand-painted in bright overglaze colours.
