Specialist Crafts air drying clay contains a small amount of nylon fibres to give it strength if the clay is to be air dried, but it can also withstand kiln firings up to stoneware temperatures of 1200¼C without any detrimental effect
Softer to work with than some of the leading brands, the shrinkage rate will be slightly more than firmer clays
If you want to kiln fire your clay, it must be wedged well to remove air bubbles and dried slowly and thoroughly before going into the kiln
Once the clay has been air dried, it can either be decorated with acrylic or gouache paints and varnished for an extra hard coating
Or if it is going to be fired, it can be glazed with traditional stoneware glazes
Please note that the quoted weights are approximate, and weights may vary
Please note: These clays can be air‐dried but will be affected by moisture of any kind
If they are not kiln fired, then they are not intended to hold liquids
If they are intended to be kiln fired, please note: Not all kiln 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
