Casting and Cleaning In 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. Casting platinum requires the same steps as casting gold, but the process is performed differently; be sure to request a technical specification sheet about casting with platinum. Re-Using If you plan to re-use platinum 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 platinum. All re-used platinum should be clean and free of debris. Composition This material is composed of 95% platinum and 5% ruthenium.
