TIPS FOR CASTING 14K ULTRA WHITE / 14K EXTRA WHITE

Using Ultra White Casting Grain

14K EXTRA WHITE CASTING GRAIN IS ALSO KNOWN AS:
X WHITE CASTING GRAIN AND
ULTRA WHITE CASTING GRAIN

• 14K Extra (X) White casting grain and 18K Extra (X) White casting grain contain a higher nickel content than traditional white casting grain and do not require Rhodium plating to achieve a good white color.
• Extra White is harder, but not necessarily more brittle than lower-nickel content alloys due to proprietary additives.
• When re-melting we recommend using 75% fresh mix. White gold alloys are typically not as reusable as yellow alloys. If there are any dark inclusions or foreign particles visible in X White scrap, it has become contaminated or depleted, and should be returned to G&S Metals for refining.
• When CASTING with X White Casting Grain, pay particular attention to the recommended quenching instructions. It is important to quench within 2 or 4 minutes. As a general rule, quench just prior to the red glow leaving the button. In most cases, X White Casting Grain may be annealed to recover from an improper quench cycle.
• X White melting temperatures are comparable to standard nickel white gold alloy temperatures. Standard investment for gold casting will provide good results.
• Casting with an induction furnace: i.e. one that you can “dial up” and control the temperatures to avoid over heating the metal. Torch melting has been successful but get very hot, very fast, which this particular alloy doesn’t like.
• The best advice for torch melting is to time yourself when melting a traditional silicon based white gold and then use the same time and technique when melting the X White Casting Grain. The problem most torch melters encounter when working with the X White Casting Grain is that they are looking for the “watery surface” that silicon based casting grain typically exhibit when they are ready to cast. Excessive silicon is not a good thing for casting grain as it causes the grain structure to become enlarged, which then allows more problems to occur around these enlarged grain boundaries. The X White Casting Grain has only enough in silicon in it to protect the metal which results in it not giving the anticipated “watery surface” to a torch melter even though it is ready to cast.
• QUENCHING needs to be done immediately after the last red has left the button.
