Core tip: by residue to identify true bogus, A) Chow bronzes as van split, in fact can't maintain the balance of the accurate. If, fei fei and slightly unbalanced, is likely to cause bronzes with residue to identify true bogus ( A) Chow bronzes as van split, in fact can't maintain the balance of the accurate. If, fei fei and slightly unbalanced, is likely to cause bronzes to the wall thickness unevenness, or have a significant casting defects. Controller for bulkhead of the homogeneous and small correction, chow tai age craftsman generally adopted similar small pieces of copper pad thickness between the inner and outer fan, the gap between the inner and outer fan remain stable and uniform, in order to improve casting quality. This in the early days of the vast majority of bronze wares are seen. But some obvious, some hidden. Gasket of the alloy and the original component is not necessarily the same, the oxidation of color is not the same. Some gasket by old bronze pieces at that time, some fragments with decorative pattern; Some spacer blocks is not obvious, or only revealed a small horn line mark. Fan inside the gasket can't completely when pouring molten copper fuses in together, as long as careful observation, always can be found. Gasket placed areas tend to be relatively regular, should be paid attention to when looking for the corresponding parts. Early whole ZuoWeiZhe, not know bronze casting method, therefore no gaskets. If no gasket trace on the ancient bronze ware, this will be an important signal of faking. Some inscriptions of the gasket around the line mark clearly, also can appear on hot strip, ZuoWeiZhe in pretend these inscriptions, the contour of the gasket ink have copied out, but it is on the whole machine imitation, but carves out mark, on the physical is not the same with the real gasket, careful appraisal when can perceive. Pottery mould fan soil, there are usually two color red, grey, black van soil did not see. Black van soil in general is a sign of foundry. Because in the foundry, the soil to add just the right amount of graphite and organic matter, these substances after carbonization is black. Most of the handed down and unearthed bronze ware, many still kept van soil. Some in obvious places, such as GUI jie, pot, You ring foot also left a small amount of trace. In this respect, can also be used as a reference when appraisal. Some bronze ware of the foot, ear is a must also have inside fan, the fan in and outside fan split, there must be the contact point. Such as the legs of the introverted personality, most have such contact point can be recorded. Contact point or characterized by a small hole, or between the inner and outer fan have supported such as copper, copper rod. Some early pseudo device, and device is to adopt the combination of welding method, do the false rust covered; Or take a large, in the bottom of the foot to combine internal and external fan, and then use another piece of copper seal, disguised. Ancient piece of fan casting bronze ware, good surface finish, decorative lies discernible, even few stomatal surface, less copper and shrinkage cavity fluid infusion is less than. And lost wax and foundry casting pseudo, often appear a few sand holes on the surface. Some even produce the defects such as shrinkage cavity. If you don't understand this kind of situation, is likely to think voids and porosity are the characteristics of the old cast.
