Delta Stoneware Clay ~ Slight Grog / Textured

Suggested firing temperature : 1120°c - 1280 °c

A pronounced speckle will appear through glaze under oxidising conditions. A lovely biscuit colour when fired. Not advisable to use on the pottery wheel as the rough texture is very hard on your hands. 

I would always advise to test how your clays and glazes interact with each other.
