Specialist Crafts White Firing Clay - 12.5kg

An excellent smooth clay which is particularly good for throwing. Fires to a white finish making it great for domestic ware too. Good green strength properties. Firing range 1100°C-1220°C, therefore suitable for earthenware work.

Please note: Not all clays are guaranteed to be impervious to liquids even if they are classed as stoneware. For pottery pieces intended to hold water or to be protected from frost damage also apply a glaze to reduce the chances water absorption, making sure to avoid pinholes or crazing of the glaze. Clays have their own firing ranges, some at stoneware temperatures but only very vitreous bodies like bone china and porcelain offer better resistance to water when fired to 1300 degrees centigrade, and even then there may be a slight moisture absorption. Always place vessels holding water on a mat to protect porous surfaces, such as wood, from damage.
