When did the two jewelry crafts, Diancui and Baked Blue, begin?

Diancui technology began in the Han Dynasty, baking blue is the blackening treatment of the surface of steel parts, and jewelry technology refers to burning blue technology, which originated from the invention of Italian craftsmen at the end of 13.

Diancui craft, which originated in the Han Dynasty, is a traditional Chinese gold and silver jewelry making process, which belongs to the auxiliary work in jewelry making and plays the role of embellishing and beautifying gold and silver jewelry.

The jewelry made by Diancui Technology has good luster, bright color and never fades. The development of Diancui craft reached its peak in Kangxi, Yongzheng and Qianlong periods of Qing Dynasty. Its superb skill level and immortal artistic value fully reflect the outstanding talents and artistic creativity of the ancient working people.

Blue-burning technology is not an independent job, but an auxiliary job to decorate, modify and increase the aesthetic feeling of color, which appears in the jewelry industry. Blue-burning process is one of the traditional jewelry processes in China. Because this "blue" can only be burned on the surface of silverware, it is also called "burning silver blue".

Silver burning blue, also known as silver tire enamel, was invented by Italian craftsmen at the end of 13, and colored transparent enamel appeared in Paris, France in 14 century. Up to now, the earliest physical object found in China is the silver-burned blue Five Blessingg Pengshou Octagonal Box from the Yongzheng period of the Qing Dynasty (1723~ 1735). There are many kinds of enamels such as sapphire, light blue, light green, red, yellow and white, which have good transparency and bright and clear colors. It is a mature product, so the origin should be no later than 17.

Extended data

1. Diancui technology is divided into soft emeralds and hard emeralds, which are divided according to the kingfisher feathers used in Diancui technology.

1, hard green

The kingfisher used to order cuisines has relatively large feathers, called jadeite, with ten left and right wings (called "big strips" in jargon) and eight tails (called "tail strips" in jargon), so a kingfisher usually only uses about 28 feathers.

2. Soft green

Soft jade is the point jade craft, and the point jade jewelry made of kingfisher's smaller feathers is called soft jade.

Second, the history of the process of burning blue

The early silver-burned enamel handicrafts were produced by the "silverware factory" set up by the Ministry of Interior and Chu Guang of the Qing Dynasty. These handicrafts are all made for court nobles, so it is difficult for us to see the names of ancient craftsmen in such works.

It was not until the late Qing Dynasty that folk silver shops began to burn this kind of utensils. The production of silver tire enamel is a complex process integrating metallurgy, casting, painting, baking, carving and hammering, which are indispensable. Common enamel colors are blue, green, red, yellow and white.
