To identify the authenticity of Qianlong porcelain, we should start from the following aspects. Looking at the glaze, most of the glaze of Qianlong porcelain has orange peel lines, and the glaze at the bottom of some utensils is wavy. Several artifacts can be seen from the blue material part of the blue-and-white six-character model. Most imitations have no orange peel lines, and the glaze is brighter than the real thing, so there is no sense of wealth. Second, the vessels are full, and the vessels are full during the Qianlong period. The red and blue in the official kiln are generally loach-shaped, with glutinous rice flour. The imitation tire feet are neat and hard, and the mechanical process is obvious. Third, look at the colored materials. Qianlong blue-and-white porcelain is blue and elegant, and the fruit and leaf petals in the decoration are colored with dot dyeing, with different shades. Imitations are often painted by smearing, and some are painted by dot dyeing, but blue and white pigments are thin and float on the surface. Fourth, look at the decorative patterns, which are mostly dragon and phoenix patterns and Ji Xiangwen. In addition to some decorative styles inherited from Kangxi and Yongzheng, there are a variety of multi-color over-the-glaze enamels, such as overlapping colors, painting, hollowing out and colored glaze, which are bright and unique. The imitated pattern is gloomy and dull, and the painting style is unremarkable. 5. Looking at the characters, we can see that the output of porcelain in Qianlong period was large, and the writers changed hands several times, and the characters changed greatly, among which the strokes of the words "Qing", "Gan", "Long", "Nian" and "Zhi" were slightly different. There are also many folk kilns that write the year number of Qianlong, and also write the six-character seal script of "Qianlong Year System in Qing Dynasty". In the identification, the regularity of characters is generally used as the basis for distinguishing official kilns from private kilns. Most of the general folk kilns are sloppy, and it is not difficult to distinguish them carefully. 1.
