I realize this problem is a result of my port planning, but…I am trying to fulfill a wholesale order and need standard white stoneware 630, but the supply store I typically use is out of stock. I have a deadline and need the clay asap. To fulfill the rest of order and make it consistent with prior glaze results I need that clay or something very similar. Does anyone have a recommendation for a very similar clay that may have similar glaze results? Or does anyone in Chicago area have just 25lbs of 630 to sell to me?
