Ceraline Cobalt Black – Raw Oxide Crayon  £5.29

All colours are available in either earthenware (1000 – 1150°C) or stoneware (1150 – 1280°C). The earthenware crayons can be used at stoneware temperatures, but the colours will fade slightly. The stoneware crayons cannot be fired at a low temperature as the colours will not adhere to the vessel.

Wax crayons are a great way to create unique effects by themselves or combining with underglazes and glazes.
