Look at the surface: the surface is evenly and densely attached with a protective film, which can isolate the air, avoid the oxide on the surface of the copper lamp, and also increase the degree of Guanze on the surface of the copper lamp.
Look at the color: the color of a good copper lamp body is natural and smooth, except for the highlight point, there is no color spot, the color is consistent and uniform, the color is firm, and it is not easy to fade and fall off. Due to the lamination, it is also extremely resistant to oxidation.
Look at the workmanship: the workmanship of high-quality copper lamps, whether it is a large area of the lamp body outline, or a small range of local carving, a petal, a crescent, can be said to be seamless, all reflect the ingenuity of skilled craftsmen.
Second touch: touch the surface.
After looking at the appearance, if this copper lamp can still make you more satisfied, we can move on to the next step, touch.
Touching the surface of the copper lamp, the surface of the high-quality copper lamp has been meticulously polished and polished. There are no burrs and places that can make your hands uncomfortable. Suffice it to say, anything you can touch with your hands must be smooth, rounded, and with the characteristic cool feeling of copper.
Three listening: Listen to the sound.
Listening to the sound is also one of the ways to identify the advantages and disadvantages of copper lamps. The sound of a good copper lamp is either rich and deep, or clear and pleasant. What they all have in common is that they have a clean and noise-free sound. The sound of inferior copper lamps is erratic, hollow, and noisy.
Four scraping: scrape the surface.
After listening to the sound, if possible, we can also use the cutting method to directly identify, which is also the most effective method. Use a knife or a small file to gently scrape the whole copper lamp in the non-appearance of the place, to see what color the scraped fine crumbs are, if it is golden yellow or golden white, then more than 99% of it is pure copper lamp, if the scraped fine crumbs are white or silver, then more than 99% of it is not pure copper.
Finally, it should be noted that no matter how good the copper used in this copper lamp is, the main load-bearing parts of this lamp, such as the central pillar and lamp drum, are still steel or other alloy materials. The reason is very simple, generally copper is not suitable for load-bearing structures.
