The bronzes that have been excavated and unearthed have become rusted. It is this green rust that makes modern people more like it. At this time, people have the need to have some bronzes as decoration, which stimulates the creation of antique bronzes. The identification of antique bronzes , in the past, from the identification of patterns, modeling, inscriptions, sounds of objects, weight perception, etc., most of them have not adapted to the identification of modern high imitation goods. For high imitations processed by modern technology, it can be identified from the following aspects:
First, from the identification of copper and fetal quality: high-copy copper, if not destroyed by electrolysis, its copper is grayish white, the fracture is very rough; if the copper is destroyed by electrolysis, its placenta is gray-white powder, very loose . In ancient bronzes, the copper was red and black, the fracture was very delicate, and the lost fetal copper was also earthy red and very hard.
Second, the identification of the traces of casting: the ancient bronzes are naturally formed when casting molds, while the modern imitation bronzes, the van scars are deliberately made. Even the traces that have been turned from the ancient bronzes have become rounded and angular due to the multiple running-in during the process of turning and making the wax mold. The ancient bronzes have sharp and angular edges and are naturally smooth.
Third, identification from the hull and chemical rust: electrolytic hull and chemical rust, due to the formation time is too short, the nature is extremely unstable. If it is put into the water for 10 minutes, it will be slightly dried after the skin is dried and dried. Because the chemical reagents in this type of leather case and rust are not completely removed, they will continue to react when exposed to water. The husk and rust of ancient bronzes are stable oxides and carbonates that do not change when exposed to water.
