The accurate gold content of gold jewelry samples to be determined.
(2) Chemical method: also known as reagent test method. Gold is insoluble in separate nitric acid, sulfuric acid, and hydrochloric acid, and silver and copper ingredients can be dissolved with nitric acid. Take gold decorative sample. Putting nitric acid on a certain part, if gold will not change color, if it is silver products, it will generate silver oxide and turn black; For gold jewelry with a gold content of more than 95 %, test with nitric acid, the surface changes very small.
How to identify gold -plated jewelry and real gold jewelry.
