Description

Get professional, repeatable results with this pure (.999) 24-karat yellow gold casting grain, alone or combined with a master alloy.

Because it is professionally produced, you can count on consistent, repeatable quality and composition over time.

Sold by the pennyweight (dwt.), minimum purchase is 0.2 dwt.

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.

Re-Using
If you plan to re-use gold castings, remove the 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.

Composition
All ingredients are kept in an oxygen-reduced atmosphere during the melting and pouring process to ensure optimum deoxidation.
