Introduction to Enamel Color Craftsmanship

Enamel crafts were mainly divided into three categories: stringed silk, micro-painted, and filled with inlaid silk. Now, stringed silk was the main trend. Most of the traditional enamels were made of red copper, and the mineral glaze was burned into colorful patterns at high temperature. The production mainly went through the processes of making the body, pinching the silk, blue, baking, polishing, gilding, etc. The materials were relatively simple, the procedures were cumbersome, and it took a long time. The production process of modern colored porcelain was as follows: first, the rough shape of the selected porcelain body was outlined with ink, and then a pattern was drawn on the oil paper with a fine needle and then patted on the porcelain body (the pattern needed to be symmetrical and aligned up and down). Then, the raw material (the same kind of paint as the underglaze blue and white, commonly known as Zhu Ming material) was used to hook the line. When hooking the line, the raw material was rubbed with sesame oil and added with Camphor oil to maintain smooth lines. After drawing the line and waiting for it to dry, he removed a layer of pot ash (the black ash at the bottom of the firewood stove in the countryside). Then, after making the glass white and painting the ground, he carried out the first burning of the furnace. The temperature was between 800 - 850 degrees. After the first burning, the painter used oil paint (rich and gorgeous colors, imported like the third generation of Qing Dynasty) to draw layers and yin and yang effects, and then carried out the second burning (the temperature was the same as the first burning). After the second burning, the color became more stable. In order to increase the visual effect, the gold was processed with 24K pure gold powder and painted with gold lines, gold fruits, and gilded edges. After the completion of the third low-temperature burning (about 620 degrees), after the third burning, the gold processing part of the kiln could be made with extremely fine sand or agate pen. Modern enameling craft could also be produced through the enameling decorative painting production equipment. The image could be input into the computer, and the computer would input the image into the program module of the decorative painting production equipment. Finally, the decorative painting production equipment would be controlled to print, and then the process could be made with the enameling consumables. The finished product had good quality and accurate image. It could be used to produce the enameling decorative painting with glass, wood, acryl, ceramic tiles, etc., and had a wide range of applications. The novel "Gilded Palm" is equally exciting.
