    Vulcan Black Stoneware (Extra Coarse) 1200-1260C

    Vulcan™ Black Stoneware (Extra Coarse) 164-VUX: 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 is obtained. Containing a very coarse grog (18-7 mesh) Vulcan Black Stoneware Coarse 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 larger-scale handbuilding. Supplied in a 12.5kg bag.

    Vulcan Black Stoneware (Extra Coarse) is not recommended for tableware. However, Vulcan Black Stoneware (Fine) is suitable for tableware.

    • Dry bending strength: 3.0 N/mm2

    • Thermal coefficient (25-500ºC): 51.3x10^-7ºC^-1

    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%. 

    Use zinc-free (Zn-free) glazes to prevent unexpected reactions such as bubbling or colour changes. Other elements that can react are zirconium (Zr) and tin (Sn). 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.
