Gilt craft production process

The gilt craft production process is as follows:

I. Introduction

The gilt craft is a traditional metal working process, which can coat the surface of the metal with a layer of gold-colored metal film, so as to give it the sense of nobility and luster of the metal. Chajin craft is widely used in ancient China in the fields of palaces, temples, religious buildings, utensils, weapons, crafts and so on, which has become one of the treasures of Chinese traditional crafts;

Two, production works

1, preparation: first of all, you need to prepare a variety of tools and materials. Tools include metal products, scrapers, brushes, whetstone, polishing cloth and so on. Materials include gold foil, gold powder, glue, metal paint and so on;

2, surface treatment: the metal products to be Tsagaing are subjected to surface treatment, removing the dirt and oxides on the surface to make its surface flat. This step requires the use of grinding stone and polishing cloth for grinding and polishing;

3, primer treatment: the surface of the metal product is coated with a layer of primer to increase the adhesion of the gold foil and to protect the gold foil primer can be selected from the copper-green, vermilion sand, dansha and other colors, in order to be coordinated with the color of the gold foil;

4, gilt treatment: the gold foil will be spread on the surface of the metal product, and flatten it with a scraper. This step requires great care and patience to avoid the gold foil tearing or bubbles. After laying the gold foil, use the brush to brush the unevenness of the surface of the gold foil, so that its surface is smoother;

5, polishing treatment: the metal products after the Brahmin gold polishing treatment, so that its surface is smoother and brighter polishing can be carried out using a polishing cloth or a machine;

6, decorative treatment: after the Brahmin gold decorative treatment of the surface of the metal products can be carried out using the gold powder, color painting Engraving and other ways. This step needs to be carried out according to the specific needs and design;

Three, gilt

"Gilt" is the gold and mercury melted into an alloy at high temperature - gold amalgam, uniformly plated on the surface of the artifacts, and then heated and baked to make the mercury evaporate. Then heating and baking so that the mercury evaporation, the plated objects due to the acceptance of heat, surface activation, and gold molecular interpenetration phenomenon, the gold will be able to be transferred to the surface of the copper ware, was golden yellow. This is all to be carried out at high temperatures, so it is also known as fire gold plating.
