Raku Crank – Pottery Craft

Ideally suited to Raku Glaze firings due to the good thermal shock resistance property.

It is a highly grogged clay with high plasticity producing an interesting texture, and low shrinkage which makes it highly resistant to warping.
Due to the large particle size some ‘spit out’ may be observed.
