(1) Look at the color (also known as looking at the surface) test: The higher the purity, the whiter the silver color, with a fine and even surface that shines with polish.If it contains lead, the surface will appear shiny with a bluish-gray color; if it contains copper, the surface will feel rough and rotten with a dryness sensation.Although the surface of oxidized silver has "black rust," its color is black and shiny. Lead, tin, and white copper have no luster and appear dull in color. (2) Weighing: The density of silver is slightly higher than that of common metals. Generally speaking, "aluminum is light, silver is heavy, and copper is neither light nor heavy."Therefore, weighing it can give a preliminary judgment on whether it is silver.If the jewelry has a large volume but is light in weight, it can be initially judged that the jewelry is made of other metals. (3) Check Hardness: Silver has a lower hardness than copper but higher than lead and tin. Therefore, use a pin to lightly scratch the surface of the object for testing. If the pin slips and leaves no marks on the surface, it can be judged as copper jewelry; if it is lead or tin, the marks will be obvious and prominent; if there are marks on the object but not too obvious, it can be initially judged as silver jewelry.Pure silver jewelry can be deformed by pulling or bending it by hand. (4) Listen to the sound and rhyme: If the jewelry is made of high-quality silver, it will have a sound without rhyme when dropped, no elasticity, and the sound will be "poo poo poo poo".The lower the quality, the lower the sound; the higher the pitch, the sharper the sound with rhyme; if made of copper, the sound will be higher and sharper with a quick and short rhyme; if made of lead or tin, the sound will be dull, short, and without elasticity. (5) Determine the color by looking at the cut edge: Cut open the silver jewelry and check the color of the cut edge. If the cut edge is silky white and soft, the surface of the jewelry is smooth and delicate. After oxidation, the surface color turns black and shiny, indicating that its color is around 98%; if the cut edge is rough and soft with a slight hint of red, its color is around 95%; if the cut edge is white with a hint of gray and slightly reddish, its color is around 90%; if it bends hard by hand and the cut edge is light red or grayish, its color is around 80%; if the color is around 70%, its surface is white-yellow and dry with a hint of red and yellow mixed together, bending hard; if the cut edge is red with a hint of black or yellow with a hint of black, its color is below 60%. (6) Characteristics of counterfeit silver: Counterfeit silver is generally made from red copper, brass, white copper, lead, tin, aluminum, etc. Its characteristics are: Red copper quality: Purple-red appearance, black-red edges, raw green embroidery. Brass material: Yellow appearance, green stubble, raw green embroidery. White copper material: Appearance is gray-white, stubble brick gray, raw green embroidery. Lead material: gray-blue, soft texture, can be scratched with fingernails. Tin quality: Silver White, soft and can be scratched with fingernails. Aluminum: white gray, relatively soft and lightweight. Silver-priced silver jewelry meets standard silver content.
