{"product_id":"10k-yellow-gold-casting-grain","title":"10K Yellow Gold Casting Grain","description":"\u003cp\u003eGet professional, repeatable results and a light gold color with this 10-karat gold casting grain.  \n\nSpecial additives reduce firescale and promote good flow and fill, resulting in a smooth cast surface. Formulated with deoxidants so you can mix 50% casting scrap with new casting grain and still get good results. \n\nSold by the pennyweight (dwt.), minimum purchase is 0.2 dwt. \n\nApplications \nAny casting method.  \n\nCasting and Cleaning \nIn general, your casting temperature should be 100˚F (37.7˚C) above the liquidus point (somewhat hotter if the castings are intricate). Use a small amount of high-quality flux when melting with an open flame. We recommend Matt’s Casting Flux™. For further cleaning, mechanical means are recommended.  \n\nRe-Using \nIf you plan to re-use gold castings, remove the copper oxides from the surface in a pickling solution or by mechanical means. We recommend a minimum 1:1 ratio of new grain to used gold. All re-used gold should be clean and free of debris. \n\nComposition \nAll ingredients are kept in an oxygen-reduced atmosphere during the melting and pouring process to ensure optimum deoxidation.\u003c\/p\u003e","brand":"Amadesa","offers":[{"title":"Default Title","offer_id":50633894658394,"sku":"602700","price":160.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/7897\/7882\/files\/602700in_473490.jpg?v=1762297391","url":"https:\/\/www.amadesa.com\/products\/10k-yellow-gold-casting-grain","provider":"Amadesa","version":"1.0","type":"link"}
