The art of porcelain engraving began in the Ming Dynasty and flourished in the late Qing Dynasty. It is a kind of arts and crafts product that uses knives to carve books and paintings on glazed plain porcelain. The engraving content includes figures, flowers and birds, landscapes, etc. The works have fresh composition and smooth lines. The figures are vivid and lifelike, and have high appreciation and collection value. The production process is: first use the tip of the knife to carve out dots and lines, and then apply ink and wax, that is, landscapes, flowers and birds or various calligraphy styles appear on the porcelain surface, which not only maintains the traditional style of calligraphy and painting, but also plays the characteristics of the crystal clear porcelain surface, achieving a complementary effect, and it is long-lasting. Porcelain engraving originated from the folk. In the late Ming and early Qing dynasties, there were already businesses specializing in ceramic engraving, but most of them were mainly flat engraving, with dot and line composition, and the artistic expression was monotonous and plain, which did not attract the attention of the world at that time. It was not until the late Qianlong period that the court specially set up the "Zaobanchu" due to the needs of the rulers to use it, and produced many excellent porcelain engraving works. At the end of the Qing Dynasty, the Imperial Household Department was disbanded, and some porcelain engraving artists lived in Shanghai, so the skill was passed down in Shanghai. There are two basic methods of porcelain engraving: one is punching and the other is hand engraving. The former is easy to express the taste of gold and stone, and the latter is easy to express the flowing and elegant lines. However, both require the author to have a deep foundation in calligraphy and painting, and the author needs to learn the knife-using methods of gold and stone engraving, and have the skills of holding the knife to chisel and use the knife instead of the pen. After years of continuous excavation, exploration, and repeated experiments, Shanghai porcelain engraving artists have pioneered the use of unique methods such as carving, engraving, grinding, rubbing, rubbing, and dyeing in works such as large screens, and then matched them with mahogany frames, making them both artistically appreciative and practical, thus showing a new style of porcelain engraving.
