Vulcan™ Black Stoneware (Medium) 164-VUM: 1200-1260C
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 are obtained. Containing a medium grog (up to 35 mesh) Vulcan Black Stoneware Medium has been formulated especially for artistic ceramics. It behaves excellently during drying/firing and its high plasticity makes it ideal for modelling. It is widely used for murals and sculpture and is ideal for handbuilding. Supplied in a 12.5kg bag.
Notes regarding Vulcan black stoneware bodies
Vulcan is not toxic according to European Rules (CLP) and also American Rules (ASTM D 4036). The manganese dioxide content in Vulcan bodies is lower than 5%: Under the CLP regulation, the manganese dioxide content required for classification as toxic must be greater than 25%. We have found that Mayco zinc-free clear glaze is suitable for use with Vulcan bodies and does not seem to suffer from the usual problems caused by outgassing from the high oxide levels in black bodies.
