Problems solved by technology

[0007] At present, the traditional black copper and silver craftsmanufacturing method mainly relies on craftsmen with mature skills, the production speed is slow, and the quality of crafts after forming is uneven. It takes a long time, and because of the craftsmanship of the craftsman, the material is wasted, which increases the production cost, reduces the production efficiency, and is difficult to produce on a large scale

Abstract

The invention belongs to the field of artware manufacturing, and relates to a manufacturing method for black copper silver routing artware. The manufacturing method comprises the following steps thatbody manufacturing is conducted; secondly, silver water is prepared, gold, silver and brass are mixed according to the proportion that the mass ratio is 0.5-1:59-64.5:35-40, then, complete melting isconducted at the high temperature of 1,200 DEG C or above, and the liquid state is achieved; thirdly, pattern dissolving is conducted, and the liquid-state silver water is dissolved into body patternsand designs; fourthly, black covering treatment is conducted, water, caustic soda, potassium permanganate and copper sulfate are prepared into a solution according to the proportion that the mass ratio is 90-110:4-6:9-11:18-22, and then the solution is evenly sprayed to the surface of a formed body obtained in the third step; fifthly, color changing treatment is conducted, the body is evenly heated to 600 DEG C-700 DEG C till a peacock blue solidified body is formed on the surface of the body; and sixthly, cleaning is conducted. The manufacturing method has the advantages that the product quality is stable, the production cost is low, and the production efficiency is high, and the large-scale production can be achieved.

Description

technical field [0001] The invention belongs to the field of handicraft manufacturing, and relates to a method for manufacturing black copper and silver handicrafts. Background technique [0002] The black copper and silver process was first created in the Yongzheng period of the Qing Dynasty, with a history of more than 280 years. It is said that a coppersmith surnamed Yue in Shiping accidentally dropped the gold ring he was wearing into the smelted copper when he was smelting copper. Later, he found that the copper ware he smelted was as black as coal, so he carved patterns on the surface of the copper ware and embedded silver. Shavings, made the earliest black copper and silver. [0003] The traditional black copper silvering technology uses copper as the tire, engraves various patterns on the tire, and then fills the pattern with molten silver (or gold) water. After cooling, it is polished and smoothed. After a long time, the bottom copper will naturally change. It is ...
