Description
Achieve professional results and a light gold color with this 18-karat yellow gold casting grain.
Special additives reduce fire scale and promote good flow and fill, resulting in a smooth cast surface. Formulated with deoxidants so you can mix 50% casting scrap with this new casting grain and still get very good results.
Applications
Any casting method you desire.
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. 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.
Features & Maintenance
• Casting temperatures are approximate; adjust for your particular alloy and application.
• Due to the manufacturing process of casting grain, the grain will vary in shape and size.
• We strive to measure quantities ordered as closely as possible; however, due to manufacturing tolerances at the mill, please allow for slight variance when ordering.
