We have developed in exclusivity a variety of
self - glazing clays. The soluble salts migrate to the surface during
drying process, developing a turquoise coloured glaze after firing.
We recommend a long drying period, so salts can better develop.
We supplied this clay in plastic body form, in 10kg.
