Description

Get professional, repeatable results with this14-karat palladium white gold grain, rated Grade 1 by MJSA and specially formulated for white gold pieces.

Special additives help prevent firescale and produce a whiteness comparable to rhodium. Contains deoxidants so you can mix 50% casting scrap with new grain and still get good results.

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 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.

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