There are several ways to identify gold and silver jewelry: ① The inscriptions are identified: real gold jewelry is engraved with fonts and marks, such as 24K, 18K, 14K, 12K, "Foot Chi", "Nine Show (Cheng)", " Wuxu (Cheng) ", and the place name of the silver building gold shop. Platinum jewelry is engraved with "Platinum", "P.T", "P.M"; silver stamped "foot silver", "nine star silver" and so on. ② Deep nitrate drip test: Nitric acid dripped in gold and platinum unchanged, dripped on copper and turned green, dripping on silver and turning black. ③ Observation and feel: real golden and bright, with heavy feel. Poor gold and imitation gold are poor, and the feel is lightweight. ④ heating test: The gold does not change color within 1000 ° C and still has gloss. The copper burning is discolored after refining. ⑤ Identification of ingredients: Domestic testing golden slate, using the grinding gold powder with the original test gold slate
