Description
Potterycrafts Raku Crank Modelling Clay has a good thermal shock resistance which makes this the clay of choice for building pizza and tandoori ovens as well as saggers, large hand-built work and sculpture. 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.
