# Best Stoneware Clay Source: https://potterynest.com/best/best-stoneware-clay Updated: 2026-09-14 Publisher: Pottery Nest. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://potterynest.com/how-we-research#our-score Stoneware is the workhorse clay of functional pottery, firing to a dense, durable body that holds liquid without glaze and survives daily use in kitchens and dishwashers. For home potters, it is the most forgiving path to finished mugs, bowls, and plates, tolerant on the wheel and compatible with a huge range of glazes. Choosing between stoneware bodies comes down to firing range, so match cone 5 to 6 bodies to electric kilns and cone 10 to gas or community kilns. Then consider grog content, since smooth bodies feel better on lips and rims while grogged bodies resist warping in larger forms. Color, shrinkage rate, and plasticity round out the comparison. These are the stoneware bodies worth loading in your studio. ## Picks ### 1. 50lb Best Mix - BMix - BMX - Mid Fire Cone 6 Pottery Clay - Rocky Mountain Clay Our score: 9.1/10 (Fit for the job 10/10 · Features and specs 8/10 · Build and materials 9/10 · Value 9/10) Rocky Mountain Clay's 50lb B-Mix mid fire Cone 6 pottery clay, a smooth, popular stoneware for wheel throwing.
