Air-Drying Clay

£9.00
Colour: Terracotta
Weight

 

Air-drying clay in a natural, buff stone or in a traditional terracotta colour that are popular choices for work that is going to be painted or glazed.

The nylon fibres in this clay give it strength when air dried but it can also be kiln fired up to 1200°C without any detrimental effect. Easier 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: whilst they can be air-dried, they will be effected 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.
