NOTICE regarding RedArt supply and clay color variation from current clay production. Cedar Heights Clay Company has been mining the RedArt clay from a different seam in their mine, internal testing has shown there may be a variation in the fired color of clay bodies containing this material. The following clay bodies may be affected 103, 104, 112, 119, 153, 205, 211, 214, 225, 259, 306, 308, 378, 417, 547, 760, 768, 800. While the physical properties of the clay remain within our acceptable specifications, changes in raw material chemistry and mineral composition may influence glaze interaction and final fired appearance. This change may or may not affect your production. We recommend customers perform production testing to confirm glaze fit, surface response, and finished fired color prior to use in regular manufacturing. Hopefully this is a short-term change and the bodies will be back to normal in the near future. We appreciate your understanding and will provide updates as additional information becomes available.
