Six commonly used methods to identify platinum 1, mark method: Platinum jewelry has a standard poke. Internationally use PT or PT, such as PT950 platinum color is 950%. 2, observation color method: pure platinum is white, bright luster, white K gold color is white beige, silver color is white. The surface color can be distinguished. 3, hand oscillating method: platinum density reaches 21.45. Through the weight test of the same volume material, platinum has a heavy feeling. It is heavier than gold (19.36), heavier than K platinum, and heavier than silver (10.45). 4, burning melting method: Platinum melting point reaches 1773OC, much higher than K platinum and silver. Generally, the welding gun cannot melt the platinum, and it can be identified to the authenticity. And platinum is unchanged after cooling. 5, gas natural method: Put the jewelry on the twisted gas stove mouth, put it on a few minutes. If the jewelry becomes red and warmed up the gas stove, it is platinum products. This is because platinum can be used as a catalyst, which prompts the gas and air to oxidize the heat in the air, so that the platinum is warmed, red, and can ignite the gas. 6, point test method: A wipes mercury on platinum, platinum will not be contaminated, while gold and silver will be contaminated with mercury. B is placed in a hydraulic bottle in the edge or middle depression of platinum jewelry in the depression of the platinum jewelry. Platinum can be used as a catalyst to promote hypoxic decomposition, and the oxygen is released up and down.
The first is the appraisal certificate issued by the authoritative agency, and then look at the printing and labels; the content of the appraisal certificate is clearly marked.
