{"id":594620710975,"title":"Cornwall Stone sub by Laguna","handle":"dm-cornst","description":"\u003cp\u003eThis Cornish Stone substitute is a calcium feldspar mineral used as a major constituent of glazes, and occasionally as a flux in bodies. Cornwall Stone is partially kaolinized, and can contain between 5-12% Kaolin. Nearly free from Iron, it is very white and opaque. \u003cbr\u003e \u003cbr\u003e Due to a 50% rise in the cost of already expensive Cornwall Stone Substitute aka MFW30\/G Spray Dried Flux, the decision was made to replace it with this affordable material. Laguna decided to market the substitute blend being used to replace Cornwall Stone in Laguna glaze production since Cornwall had become unavailable. In all Laguna's tests, at all temperatures, they found it worked the same at 1\/3 the cost (of what was quoted to Laguna Clay as the new cost of the MFW30\/G Spray Dried Flux). \u003cbr\u003e \u003cbr\u003e The product is sold as SG919 Laguna Cornwall Sub. \u003cbr\u003e \u003cbr\u003e The Typical Analysis comparisons below illustrate that there are only small variations in chemical composition, which show SG919 Laguna Cornwall Sub as a more chemically similar substitute for the natural Cornwall Stone.\u003c\/p\u003e \u003ctable style=\"width: 700px; height: 106px;\" border=\"1\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd style=\"text-align: center;\" colspan=\"7\"\u003eComponent Concentration\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd style=\"text-align: center;\"\u003eProducts\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e \u003cdiv\u003eSiO2\u003c\/div\u003e \u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e \u003cdiv\u003eAl2O3\u003c\/div\u003e \u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e \u003cdiv\u003eK2O\u003c\/div\u003e \u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e \u003cdiv\u003eNa2O\u003c\/div\u003e \u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e \u003cdiv\u003eCaO\u003c\/div\u003e \u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e \u003cdiv\u003eTiO2\u003c\/div\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd style=\"text-align: center;\"\u003e \u003cdiv\u003eSG919 Laguna Cornwall Sub\u003c\/div\u003e \u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e73\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e16\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e7.4\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e2.6\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e.6\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e.2\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd style=\"text-align: center;\"\u003e \u003cdiv\u003eCornwall Stone\u003c\/div\u003e \u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e73.76\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e16.33\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e4.3\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e3.3\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e1.81\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e.15\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd style=\"text-align: center;\"\u003e \u003cdiv\u003eMFW30\/G Spray Dried Flux\u003c\/div\u003e \u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e77.39\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e14.06\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e3.34\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e3.56\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e.42\u003c\/td\u003e \u003ctd style=\"text-align: center;\"\u003e\u0026lt;.05\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003cp\u003eMelting range 2102°F-2462°F \u003cbr\u003e \u003cbr\u003e Additional Technical Support\u003cbr\u003e Laguna Clay Company California | 800-452-4862 ext 213\u003cbr\u003e Laguna Clay Company Ohio | 800-762-4354 ext 207\u003c\/p\u003e \u003cp\u003e\u003ca href=\"http:\/\/www.lagunaclay.com\/support\/pdf\/Cornwall_stone_substitute_support_SG919.pdf\"\u003eCornwall Stone Laguna Substitute Support\u003c\/a\u003e\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e","published_at":"2018-04-04T12:02:16","created_at":"2018-04-04T12:02:16","vendor":"Krueger Pottery Supply","type":"General Raw Materials","tags":["Material Type_All the Rest"],"price":350,"price_min":350,"price_max":11250,"price_varies":true,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":true,"all_variant_ids":[7219304726591,7219304759359,7219304792127,40186966245439,40186966278207],"variants":[{"id":7219304726591,"product_id":594620710975,"product_handle":"dm-cornst","title":"Cornwall Stone sub by Laguna – 1lb Bag(s)","option1":"Cornwall Stone sub by Laguna – 1lb Bag(s)","option2":null,"option3":null,"sku":"CORNST-1","requires_shipping":true,"taxable":true,"featured_image":null,"image_id":null,"available":true,"name":"Cornwall Stone sub by Laguna -
