Distinguishing metal badges from four aspects
In the local collection market, fake badges show a growing trend, especially the selection of advanced technology imitation of rare badges, but also fish, making it difficult to distinguish between true and false. The fake badge contains two categories, The imitation (that is, the false seal made of the model of the genuine seal) and the imaginary product (which refers to the false seal of the fake, imaginary forgery), in which the imitation is more common. To distinguish the authenticity of the badge, we can draw on four methods of "looking, smelling, asking and cutting" of TCM to carry out "diagnosis".
That is, the investigation badge appearance natural slurry, enamel coating, paint effect, electroplating luster, setting picture, text features and so on. Genuine badge enamel color positive, lacquer bright, has a good adhesion and high temperature resistance, corrosion resistance and other characteristics. Fake badge is painted with paint, natural fast dry curing, lacquer surface has cascading marks, color gloss is poor and too bright, time long lacquer film easy to shell up the layer. The exterior of the badge electroplating layer, light and dark, thickness is also an important basis for distinguishing the authenticity.
That is, to be knowledgeable, or to obtain relevant knowledge from the books and periodicals, or to consult with the expert collectors to judge, or to compare with the same badge, and so on. Now published badge Appreciation books are "China's Badge", "badge and its preservation" and other dozens of parts. In recent years also presented a "badge network", "Mao Zedong Badge Preservation Network" and other dozens of professional websites, the preservation can learn about common sense and quotes, to improve the identification can be helpful.
Refers to understanding the origin of the badge, historical setting, planning modeling, aesthetic principles, process methods, manufacturing process and so on. The manufacture and distribution of each badge, especially the early badge, is based on a certain historical event. In addition to a few handmade badges, the process of the mechanism badge is roughly: Planning drawings-opening molds-repairing molds-selecting blanks-Stamping billet-electroplating-enamel (or paint)-on pins-packaging. Although the types of badges vary widely, their craftsmanship is much the same.
Refers to the distinction from the raw material and density of the badge. An important process in the manufacture of badges is the stamping of billet. The larger the tonnage of the press, the higher the density of the coat of badges, and the higher the pros and cons of the badge to maintain a high smooth and finish. Early badges are mostly made of copper, because the data hardness is low, plastic deformation is strong, the choice of steel mold by gravity stamping, badge on the back of the bump indentation is particularly obvious, the inscription is particularly clear.
