(2) weighing: silver density is slightly greater than the general common metal, generally speaking: "aluminum light, silver heavy copper is not light and not heavy." Therefore, weighing can make a preliminary judgment on whether it is silver. If the jewelry volume is larger and lighter weight, you can initially judge the jewelry is other metals.
(3) check the hardness: silver hardness is lower than copper, and lead, tin, so use a large needle to scratch the surface of the physical object a little hard to test, such as needle slippery, the surface is difficult to leave traces, can be judged to be copper jewelry; such as lead and tin texture, then the traces are very obvious, prominent; such as physical objects to leave traces and less obvious, can be preliminarily judged to be silver jewelry. Pure white silver jewelry with hand pull, folding can make it deformed.
(4) listen to the sound rhyme: jewelry such as high color silver, the sound of the ground without rhyme, no elasticity, the sound of "blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah. The lower the color, the lower the sound, the sound is more pointed and higher with rhyme; if the copper, the sound is more high hundreds of pointed, rhyme sound sharp and short; if the lead, tin texture, the sound of the ground is dull, short, no elasticity.
(5) look at the stubble fixed color: the silver jewelry cut open, look at the stubble color, if the stubble silky white and sheep, jewelry surface smooth, delicate, oxidation of the surface color is bright, can be determined that its color in 98 or so; if the stubble is thick and soft, slightly red, color in 95 or so; the stubble white and gray, slightly red color in the left and right 90 or so; bending the harder, stubble reddish or greyish The color of the silver in about 80; color in about 70, the surface of the silver, white and yellow and dry, stubble slightly red, yellow and both, bending hard; if the stubble red with black, yellow with black, the color has been in 60 or less.
(6) the characteristics of counterfeit silver: counterfeit silver is generally made of red copper, brass, copper, lead, tin, aluminum, etc., which is characterized by: red copper: appearance of purplish-red, stubble black-red, green embroidery. Brass: yellow appearance, stubble bean green, green embroidery. White copper: off-white appearance, stubble brick gray, green embroidery. Lead: gray-blue, soft, with a fingernail can scratch the road. Tin: silver-white, soft, with a fingernail can scratch the road. Aluminum: white-gray, soft and light. Silver jewelry variety, complex color. Silver jewelry are generally mixed with some other metals to varying degrees, so how to identify silver jewelry?
(1) check the hardness
The higher the color of silver jewelry, the softer the texture, the more white and smooth surface. To 60 grams of silver bracelet, for example, such as a hand pull on the open, no elasticity, its color in about 95%; such as a bit of elasticity, color in about 80% to 90%; such as elasticity is larger, the color is below 70%.
(2) look at the stubble
Silver jewelry cut or folded open, look at the color of its stubble. If the jewelry is soft, stubble rough and soft, slightly reddish, color is about 95%; such as hand bending harder, stubble white with gray, or slightly reddish, color is about 90%; such as hardness, stubble reddish, yellowish-white or gray, color is about 80%; such as the bending hard, stubble reddish, slightly yellowish, yellowish, yellowish and other colors, color is about 70%; such as stubble reddish-black, or yellowish black, color is about 60%. The color of the stubble is about 60%.
(3) silver medicine wipe test
Silver jewelry in the test stone grinding out the silver channel (the same as the test gold), with silver medicine (silver medicine is mixed with silver powder and mercury into a limp form) in the silver channel coated, hanging silver medicine more color is high, hanging silver medicine less color is low, do not hang the silver medicine for fake.
(4) color method
The eye to identify its color and authenticity. High color, looks white, delicate, glossy, and printed on the jewelry manufacturers, store number and other markings; low color, the color is yellowish, rough workmanship; fake silver jewelry color gray, not polished.
(5) bending method
Finger pinch bending, color high soft and pliable, easy to bend and not easy to break; quality of the bending of the second harder, or barely bending, and some can not even use a finger bending; silver-covered bending or a few hammers will be cracked; fake can not withstand the bending, easy to break.
(6) throwing method
Color high silver jewelry heavy, thrown on the board jumped not high, there is a "puh-tah" sound; fake or low color is light, thrown on the board bounced very high, the sound is relatively crisp.
(7) Nitric acid identification method
With a glass rod, nitric acid drops in the silver jewelry filed at the mouth, color high brownish-beige, hidden green or greenish; color low dark green, or even black.
In addition, the purchase of silver jewelry, but also from the following four aspects of quality selection:
(1) look at the welding. Some silver jewelry is soldered, so look at whether the soldering is clean, there is no false soldering or open soldering phenomenon.
(2) Look at the brightness. Requirements for pure plating color, brightness.
(3) Look at the inlay. To be firm, square.
(4) Look at the hook and claw. To see the hook claws have no burrs, whether it is solid, scraping clothes, wear whether it is convenient. Good luck
