|Mudlarking Finds: Creamware and Pearlware hand painted in pratt colours|
In this period artists were constrained in the colours they could use. Only colours that could withstand the high kiln temperatures required to fire lead glaze were available to them, namely cobalt for blue, copper and lead for greens, manganese oxide and iron were mixed to produce brown, orange was produced by adding iron oxide to yellow oxide. But there is something even more specific about the tone of Pratt colours.
