Porcelain engraving, also known as porcelain engraving, is to "embroider" porcelain out of the kiln with a knife and color, so it looks like pen and ink, and feels like hand. The buds of porcelain engraving appeared in the Southern and Northern Dynasties in my country, but it was only occasionally used for compensatory artistic processing, not porcelain engraving in the true sense. In the Song Dynasty, my country's ceramics industry flourished, and a large number of exquisite and high-quality porcelains continued to come out. When the emperor and some dignitaries enjoyed porcelain, they often wrote poems and painted on the crystal jade glaze to entertain themselves. In order to preserve the pen marks and ink marks forever, the skilled craftsmen were ordered to engrave them, and porcelain engraving was officially born. However, due to its difficulty in creation, it has never been widely circulated among the people. It was not until the late Ming and early Qing dynasties that it began to become popular among some craftsmen and calligraphers and painters, making porcelain engraving an independent folk art. Porcelain engraving technology, there were some kinds of technology in Nanjing in the late Qing Dynasty, and works were also published by the Municipal Arts and Crafts Company and the Arts and Crafts Research Institute in the 1960s and 1980s. In 1991. Teacher Tao Shucheng began to study porcelain engraving due to his curiosity and hobby. After decades of painstaking research, he has achieved certain artistic achievements in porcelain engraving. His representative work, "A Thousand Miles of Yangtze River", reproduces the only masterpiece handed down by the famous Southern Song Dynasty painter Zhao Fu. The whole work is magnificent and completed in one go. This work has been reported by many TV stations and newspapers, and participated in the Fourth Nanjing Art Festival and the First Nanjing Folk Art Exhibition, and won the Excellence Award. In January 2007, it participated in the First Oriental Arts and Crafts Capital Expo sponsored by the China Folk Artists Association and the Jiangsu Federation of Literary and Art Circles, and won the Spring Flower Award (the highest award for arts and crafts in Jiangsu Province). Nanjing porcelain engraving has a history of nearly a hundred years and needs to be passed on, but the prospects are not optimistic. It is on the verge of being lost and urgently needs to be protected and passed on.
