Is the ancient tin ware of high value?

There are many kinds of tin ware (tin crafts), and the content and quality of tin are different. So how to distinguish the advantages and disadvantages when buying tin ware?

Distinguishing tin ware pays attention to "sound, color, quality and workmanship"

Smell its "sound" first: pure tin has good ductility, so it is called "ringing tin" because of its distortion and sound. Handicrafts are distorted, so you can't use this method when you buy them. You can use a simpler method to "smell the sound": gently sweep the tin ware from your palm with your nails, and 97% of the alloy tin ware has a clear metallic sound and a short echo; 99.9% of the tin sound is neither crisp nor bright, and there is no echo. It is a first-class tin ware. The book Dian Bu records that "only Mengzi tin is famous in the world ... its factory name is old. Old tin will ring. "

Then look at its "color"

Pure tin, color as silver, bright as a mirror! After polishing, 97% of the tins are bright and not white, which belongs to dark brightness. After polishing, 99.9% of the tin ware presents bright silver, which belongs to the first-class tin ware and looks like silverware. In modern times, the "spot tin" originated in Gejiu, Xi Du, which is characterized by a purity of 99.9%. In addition to the "silver" polished, it can also present the texture effect of black, white and gray, making the tin ware exquisite and colorful, and it is a beautiful tin ware.

Third, distinguish its "quality".

Quality refers to the purity of tin ware. The higher the purity of tin ware, the more durable it is. Packaged food is not only harmless, but also can keep fresh for a long time. Low-purity tin products are perishable and unfit for eating. Most of the imported tin wares are marked with purity, while most of the domestic tin wares are not, but we can know their source slightly. In Malaysia, Thailand, Singapore and other places, the tin content is mostly 97%, claiming to be pure tin; 99.9% of all tin vessels in the world are produced by the old method, that is, pure tin in the true sense, or high-purity tin and refined tin. If the content is less than 97%, it belongs to tin riding device, and its practical value and collection value are not high, so it is not recommended to buy it.

Reward his "work" in the future.

Work refers to the processing of tin ware. The process of tin ware depends largely on its purity. 97% and below tin ware is hard and suitable for machining. The processed tin ware is often integrated and has obvious relief effect, but its sealing is not the best. Therefore, tea cans are generally designed with two layers, inside and outside. 99.9% of the cans are soft in texture and have strong handmade characteristics. A work is composed of several parts, which can show the advanced carving and hollowing technology. High purity tin has good sealing performance. You only need a shell to achieve this effect. You can often find that it will bounce back when you cover it hard. That's the reason.

Then there is "price". Tin itself is a precious metal, and every finished product should have its value. If the retail price is too low, this product is suspected of alloy tin, which is a safety hazard!
