Sold by the pennyweight (dwt.), minimum purchase is 0.2 dwt. ApplicationsAny casting method. Casting and CleaningIn 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. Re-UsingIf 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. CompositionAll 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":51601525178714,"sku":"601720","price":948.7,"currency_code":"SAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0934\/7897\/7882\/files\/601720_820313.jpg?v=1762340034","url":"https:\/\/www.amadesa.com\/ar-sa\/products\/de-ox-14k-white-gold-casting-grain-ultra-nickel-white","provider":"Amadesa","version":"1.0","type":"link"}
