The chemistry of this product is what makes this kaolin so special.  Low levels of titania provide unrivaled translucency that cannot be found in domestic Kaolins.  A high flux content means \nyou can use more clay and less feldspar, making up for lower \nplasticity.  Grolleg is truly a high performance kaolin, with excellent\n fired whiteness, strength for plastic making, and good fluidity for \ncasting applications.\u003c\/p\u003e\n\u003cp\u003eYou will find Grolleg in formulations for pottery, tableware, and \nelectrical porcelain production.  With clay reserves conservatively \nestimated at between 25 to 30 years, this clay will be available for \nyears to come.  \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e","brand":"Sheffield Pottery","offers":[{"title":"1 Pound","offer_id":67286244327795,"sku":"RMENGGRO-1","price":2.45,"currency_code":"USD","in_stock":true},{"title":"5 Pounds","offer_id":67286244360563,"sku":"RMENGGRO-5","price":11.5,"currency_code":"USD","in_stock":true},{"title":"10 Pounds","offer_id":67286244393331,"sku":"RMENGGRO","price":22.0,"currency_code":"USD","in_stock":true},{"title":"25 Pounds","offer_id":67286244426099,"sku":"RMENGGRO-25","price":52.5,"currency_code":"USD","in_stock":true},{"title":"55 Pounds","offer_id":45113708609858,"sku":"RMENGGRO55","price":77.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/5508\/2050\/files\/RMENGGRO55-2_2f4f51e0-998f-441b-b483-21e246f41200.jpg?v=1791876657","url":"https:\/\/www.sheffield-pottery.live\/products\/english-grolleg-55-pound-bag-rmenggro55","provider":"Sheffield Pottery Inc.","version":"1.0","type":"link"}
