Earthenware clay is the most versatile in terms molding, carving and glaze application. Our clay becomes an eggshell color, firing at 2100 degrees F in gas kilns. While being more lightweight than stoneware, baking to the point of vitrification gives it exceptional strength. Our earthenware is lab tested and accredited as frost-proof down to zero degrees. It is compatible with a variety of glazes, allowing for planter designs that match a limitless array of home decor.
