This is a reformulation of the original Flint Hills 5/6 Black. Kansas Clay intensified the color and switched to a slightly finer mesh fireclay to reduce the light speckling in the previous version....and then renamed it with a Kansas-themed name, of course. :)
***Please note we recommend firing to cone 5. There are mixed results when fired to cone 6. Some potters report bloating, others have no issues*****
Flint Hills clays have been evaluated by a nationally certified toxicologist, and have been found to be in compliance with ASTM C-1023 and D-4236, and to not contain any material in sufficient quantity to be toxic or to constitute a chronic health hazard when used responsibly.
