The Chimney lights are produced using a technique known as slip-casting (liquid clay poured into plaster moulds) – they are cast with a white earthenware clay. After casting they are hand painted with a terracotta slip which has an addition of 25% sand – the painting process takes place on a potter’s wheel. They are then glazed on the inside with a white tin glaze and kiln fired.
