Description
Get clean castings that are easy to finish with this 14-karat yellow gold clean-flow casting grain.
Additives make the grain more fluid in its molten state, making it easier to cast fine detail and minimizing porosity by reducing the tendency to absorb gas.
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.
