Platinum jewelry processing should pay attention to:
1. Foreign objects on the surface of the workpiece must be prevented (not contaminated by other metal fragments);
2. During the annealing or welding process, the support frame contaminated by other metals shall not be used. Also, refractory supports should be used when welding, not charcoal.
3. Protect your eyes. The white light and ultraviolet rays produced by high-temperature welding are much higher than the naked eye can bear. Long-term exposure to radiation can cause arc burns to the eye, possibly resulting in permanent retinal damage. When welding platinum, a welding protection filter must be used to make it safer. Platinum alloys have strong oxidation resistance. After careful polishing, in a static state, it will never lose its platinum luster. High polishing can be plated with white rhodium to improve surface hardness. Due to the high reflectivity of rhodium, the brightness of the light will remain unchanged for a long time, which will make platinum alloy jewelry even more brilliant.
