My customers love it. ### ⭐ Disappointing results *by C***S on August 4, 2025* Disappointed with the speckled clay. I was very excited to fire this clay but the grog is massive. When fired it is very bumpy and sharp. Ruined integrity of the glaze. I wouldn’t recommend this speckled clay and won’t buy again. ## Frequently Bought Together - SIO-2 PRNI Black Stoneware Ceramic Pottery Clay | 27.6 lb, Cone 5-6 | High Fire Kiln-Fired Clay for Wheel-Throwing, Hand Building, Modelling - Create Pottery and Sculpted Artwork, Ready-to-Use - SIO-2 Upsala Blue Porcelain Ceramic Pottery Clay | 11 lb, Cone 6-7 | High Fire Kiln-Fired Clay for Wheel-Throwing, Hand Building, Modelling - Create Ceramics and Sculpted Artwork, Ready-to-Use --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/529795265-sio-2-prni-black-high-fire-stoneware-clay-27-6](https://www.desertcart.it/products/529795265-sio-2-prni-black-high-fire-stoneware-clay-27-6) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-15*
