Witgert Molorak Raku Clay white 10 kg (30 sf 40)

Witgert Molorak 30 sf 40 is a finely grogged Raku throwing and building clay with a high molochite content. Its special composition ensures high resistance to temperature fluctuations and makes the clay ideal for Raku firing.

Due to the low coefficient of thermal expansion of molochite, particularly fine craquelure structures form in the glaze. At the same time, the surface remains pleasantly smooth and easy to rotate.

Ideal for precise work, vessels and sculptures up to approx. 40 cm in height.
