Witgert Rakuvaria Extreme Clay White 10 kg

Witgert Rakuvaria Extreme White is a very strong and coarsely grogged raku and sculpture clay for large, dynamic pieces. With a 60% grog content, it offers maximum stability during rapid raku firing.

The coarse grain ensures high stability, low deformation, and reduced cracking. Ideal for hand-building ceramics, sculptures, and experimental firing techniques.
