Important advice:

The vividness of the spots of LUNA clay is caused by natural minerals that may include traces of other minerals that can rehydrate after firing at a low temperature and cause flaking. To avoid it, it is recommended to fire the bisque at a higher temperature (1050-1080ºC / Cone 04) and increase the soak time. If you work directly in single firing, the problem does not arise.

(*) Firing range recommended for the clay to develop its best performance, both in terms of technical and safety characteristics, under conventional firing conditions. The color samples may show temperatures outside the recommended range to provide a broader view, but these are pieces fired under controlled conditions.

Description

Conveniently comes filmed-wrapped in a 27.6 lb. (12.5 kg) package

This clay features melting minerals that form a captivating surface, with dark specks in varying sizes and shades standing out against an ivory-white base. It has a high concentration of fine chamotte (0-0.2 mm), ensuring excellent performance during both drying and firing. Perfect for artistic ceramics, it pairs beautifully with transparent glazes to highlight the vibrant speckled effect.

Suitable for tableware (food-safe), according to ISO 6486:1999.
