High-fire pottery ... ^8-10 ... where skill, clay, glaze and fire combine to produce the most stunning works of ceramic art. Different methods of firing to reach these temperatures change the final appearance of both clay and glaze. The clay sample tiles (below) were fired in both oxidation (electric-left) and reduction (fueled-right) atmospheres. Highfire clays are considered foodsafe, even when unglazed, when fired to their full maturity at ^8-10.
Each bag of clay is 25 lbs.
Our boxes are 9" x 9" x 14" and hold 50lbs |

**Santiam (CC531)
A r ich, warm red-brown color is the draw for a great stoneware. This grogged and sanded body is plastic and versatile for throwing or slab work. Works well for any size work from small to large. Popular with sculptors, too, for its strength in construction! New & improved formula due to raw material changes and to make it more friendly for firing! This clay contains natural iron - spotting may occur! ** Please test!
**Due to a critical material being discontinued, we will discontinue this clay when our stock is depleted. We have 4500# left as of 1/27/25.
