cold-painting

Decoration, also known as cold pigments, on ceramics painted in oil or lacquer-based colours that, unlike enamels, are not fused onto the surface by firing. Even when coated with varnish, the colours are prone to flaking and wear. Cold pigments were used on some Meissen red stoneware and Berlin faience, but few examples survive.
