The name of coloured glaze can be said to be the name of ancient glass in China, which evolved from now on. Of course, this is glass in a narrow sense. In ancient times, coloured glaze was also called medicinal jade. This statement is more accurate. However, even in the Ming Dynasty, very incomplete craftsmanship was still protected by the hierarchy. At that time, the glass was very opaque, so it was called medicinal jade.

"Ming system" contains: the accessories awarded by the emperor to the champion are medicinal jade, which can only be matched with more than four products.

Characteristics of coloured glaze

1, the production process is lengthy: from conception, design, carving, firing, finishing and polishing to the completion of the work, it takes 47 delicate and complicated manual processes to complete.

2. Hand-made: workers must master superb technology to operate. Each process has its own uncertain changing factors, which need repeated experiments in the process, and the colors of the works are the same, which makes it extremely difficult to make.

3. One model and one product: one model can only burn one work, and cannot be used twice. Large and complex works even need to be fired many times to complete. Low success rate makes work more valuable.

4. High-temperature sintering: the selected raw materials are melted into crystal glass of various colors at a high temperature above 65438 0400℃, and after repeated cleaning, they are put into a mold according to the proportion of materials used in the work, and strict heating and cooling curves are set. The furnace temperature must be controlled within 65,438 0,000℃ 5℃. The firing process lasts more than 15 days, so that the crystal raw materials are accurate to every detail.
