It is a blend containing mostly SGP#1 and some OM#4. It is blended to specification (thus the blend is adjusted as the constituents vary to maintain physical properties). KT1-4 is slightly less plastic than CDI blend, but more plastic and thus less sensitive to deflocculants than SGP.\u003c\/p\u003e\n\u003cp\u003ePhysical Properties\u003cbr\u003e ===================\u003cbr\u003e Water of Plasticity*: 37.0%\u003cbr\u003e pH: 4.4\u003cbr\u003e C.E.C., meq\/100g: 11.0\u003cbr\u003e Specific Surface Area, sq metre\/g: 24.4\u003cbr\u003e Soluble sulfur+: Low\u003c\/p\u003e\n\u003cp\u003eP.C.E.: 32\u003c\/p\u003e\n\u003cp\u003eParticle Size, Microns: 20 10 5 2 1 0.5 0.2\u003cbr\u003e (% finer than) 99% 97% 93% 81% 72% 56% 35%\u003c\/p\u003e\n\u003cp\u003eFired Properties\u003cbr\u003e ================\u003cbr\u003e Cone 5 10\u003cbr\u003e ----\u003cbr\u003e Total Shrinkage: 13.0% 14.5%\u003cbr\u003e Absorption: 10.0% 1.0% \u003cbr\u003e\u003c\/p\u003e","brand":"Sheffield Pottery","offers":[{"title":"5 Pounds","offer_id":67286237249907,"sku":"RMKENKT14-5","price":8.0,"currency_code":"USD","in_stock":true},{"title":"10 Pounds","offer_id":67286237282675,"sku":"RMKT145","price":15.0,"currency_code":"USD","in_stock":true},{"title":"25 Pounds","offer_id":67286237315443,"sku":"RMKENKT14-25","price":35.0,"currency_code":"USD","in_stock":true},{"title":"50 Pounds","offer_id":45113728434498,"sku":"RMKENKT14","price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0677\/5508\/2050\/files\/KT1-4_ball_800x_aa7c6514-8d67-4b8d-96ac-fd5b835731c8.jpg?v=1696880425","url":"https:\/\/www.sheffield-pottery.live\/products\/kentucky-kt1-4-50-pound-bag-rmkenkt14","provider":"Sheffield Pottery Inc.","version":"1.0","type":"link"}
