Witgert Raku and stoneware clay 11 sf 0–0.2 40 white 10 kg

Witgert 11 sf 0–0.2 40 is a very finely grogged raku and stoneware clay for precise throwing and hand-building work. Its fine grain and high grog content of 40% combine high stability with excellent throwability.

The clay is prepared using a wet process and contains added kaolin, which gives it a particularly bright, even firing color. It is ideally suited for taller pieces and delicate shapes.

The mass begins to sinter at around 1280 °C and is therefore also suitable for classic stoneware applications.
