These pots were burnished as green ware then fired to a low temperature in the kiln. This preserved the sheen on the surface of the pot and gave them some stability but left them without colour.
They were then taken into the garden and pit fired with salt, seaweed and copper compounds. The result is a unique mixture of colour and carbon.
The peach colours come from the salt in the seaweed and the black carbon from the smoke. The finished pieces are waxed and polished to help enhance the sheen.
