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.
A note about manganese
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%.
Glazing Vulcan bodies
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 glaze 'milkiness' issues caused by outgassing from black bodies.
