In plastic bodies, for example, the moisture retention means that items will dry slower and this can lead to a more even drying process. \u003c\/p\u003e\n\u003cp\u003ealthough mfg. say it can be used alone @ cone 10, this clay is highly plastic and shrinks excessively and feels sticky when used alone. Cream to buff in oxidation (low iron). Can be used w\/10% feldspar at cone 5‐6 for a throwing body but recommended to add grog for more tooth. The mine closed in 1989, but a new source is now available.\u003c\/p\u003e","brand":"Sheffield Pottery","offers":[{"title":"5 Pounds","offer_id":67286236594547,"sku":"RMFOUHIL-5","price":5.25,"currency_code":"USD","in_stock":true},{"title":"10 Pounds","offer_id":67286236627315,"sku":"RMFOUHIL","price":9.5,"currency_code":"USD","in_stock":true},{"title":"25 Pounds","offer_id":67286236660083,"sku":"RMFOUHIL-25","price":21.25,"currency_code":"USD","in_stock":true},{"title":"50 Pounds","offer_id":45113720701250,"sku":"RMFOUHIL50","price":21.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/5508\/2050\/files\/30347__64217.1656726906.jpg?v=1696615641","url":"https:\/\/www.sheffield-pottery.live\/products\/foundry-hill-cream-ball-clay-50-pounds-rmfouhil50","provider":"Sheffield Pottery Inc.","version":"1.0","type":"link"}
