Clays included in this category contain a significant percentage of Kaolin in them. For your convenience, we have included several clays that are not technically porcelains by true definition, but which are commonly thought of as porcelain due to their whiteness, smoothness, and general working properties (like B-Mix). Please use the Firing Range Filter to narrow down your choices and find the right clay for your needs!

Winter Wind is a reformulation of the Flint Hills Cone 5/6 Porcelain. You should not notice a difference in workability or glaze fit. The body is almost identical, but the original included a bag of talc. We removed the talc and added a small percentage of 120mesh molochite to maintain the average shrinkage percentage in the original version. As a bonus, that addition also increases the green strength and reduces warpage a bit as well! Average Shrinkage at Cone 5: 11.53% Average Absorption at Cone 5: 4.2% Average Shrinkage at cone 04 bisque: 6.38% Average Wet to dry shrinkage 5.5%
