Potclays Vulcan Black Stoneware (Fine) CLY

Potclays Vulcan Black Stoneware (Fine) 1200-1240C 12.5kgs

Vulcan Black Stoneware is unlike any other on the market, providing an unusual intense brown-black colour when fired in an oxidising atmosphere. In a reducing atmosphere a metallic finish with shades of blue is obtained (Note: Too-heavy reduction will cause bloating).
