Umber is a heavily pigmented raw clay that is maintained for staining cement, mortar and paint (for ceramics we must tolerate some variations e.g. particle size, chemistry). You may see differences in the pugged or bisque fired color from run to run, this happens when we have to change suppliers or grades of the umber product - however the fired color at cone 6 will still be normal.\u003c\/p\u003e\n\u003cp\u003eProcess Properties\u003cbr\u003eThis clay is plastic, it throws and forms well (even if soft). It generates plenty of slip on throwing and is smooth.\u003c\/p\u003e","brand":"Plainsman Clays","offers":[{"title":"Default Title","offer_id":51898007027995,"sku":"4787","price":53.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0952\/6896\/2587\/files\/28408.png?v=1757539616","url":"https:\/\/archiebrayclay.com\/products\/plainsman-coffee-clay","provider":"Archie Bray Clay Business","version":"1.0","type":"link"}
