Golden brown stoneware clay creates a great toasty finish. It has been developed with 40% fine grog 0-0.5 mm (up to 35 Mesh).
The high content of grog provides a nice textured finish as well as additional strength and resilient characteristics.
Formulated for artistic ceramics, it is ideal for sculpture and raku work, can also be used for wheel-throwing. The high content of grog confers an excellent behaviour during drying and firing.
It has amazing fired colour, with different tones of golden brown, highlighting reliefs and edges, you can really experiment and be expressive with this clay body.

(*) Firing range recommended for the clay to develop its best performance, both in terms of technical and safety characteristics, under conventional firing conditions. The colour samples may show temperatures outside the recommended range to provide a broader view, but these are pieces fired under controlled conditions. Cone equivalence according to Orton table for self-supporting cones, regular-SSB and 150ºC/hr heating rate.
