Description

Get a bright white color with this .950 platinum casting material. It is a great choice for your high-end jewelry pieces.

Because it is professionally produced, you can count on consistent, repeatable quality and composition over time. Pieces cast from this material can be quality-stamped as "950 PLAT."

Applications
Any casting method.

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.
