Technical method of copper relief production: cast copper relief production is a red copper handicraft developed and produced in China after long-term research and tackling key problems. It is refined through multiple processes with non rusting and non decolorizing red copper as raw materials. It is closely combined with local characteristic culture in content and form, with fine workmanship, vivid image It has the characteristics of strong three-dimensional sense, simple style and lifelike picture. The selection of copper relief is close to real life. It is a folk art spirit. It shows people's thoughts and aesthetics. This relief making technology spreads among the people and tells folk stories.

铜浮雕制作分为红铜浮雕、黄铜浮雕和锻铜浮雕。红铜浮雕又称纯铜、紫铜。红铜的延展性、导电性和耐腐蚀性很好，其中延展性是铜雕装饰的重要特性。红铜的熔点很高，不易铸造，而良好的延展性弥补了这一缺点，因此能够很容易地加工成各种造型图案。

Copper relief production is divided into red copper relief, brass relief and forged copper relief. Red copper relief is also called pure copper and red copper. Red copper has good ductility, conductivity and corrosion resistance, among which ductility is an important characteristic of copper carving decoration. Red copper has a high melting point and is not easy to cast, and its good ductility makes up for this disadvantage, so it can be easily processed into various modeling patterns.

黄铜浮雕简单的说，也就是在黄铜浮雕表面通过我们的一些加工达到一些能够展现与众不同效果的铜雕，其中化学复古法用的较多，化学药水常温发酵氧化，在不损伤黄铜表面的同时而通过药水化学反映而生成的一种黑色氧化物，后通过人工技术进行精细的表面处理而表现出多种古铜韵效果。

Brass relief, in short, is to achieve some bronze carvings that can show different effects on the surface of brass relief through some of our processing. Among them, the chemical retro method is used more. The chemical potion is fermented and oxidized at room temperature. It is a kind of black oxide generated through the chemical reaction of Potion without damaging the brass surface, After fine surface treatment by artificial technology, it shows a variety of ancient bronze rhyme effects.

锻铜浮雕(又叫錾铜或敲铜)，是利用铜材料的延展性兴起来得錾刻工艺，是我国传统手工艺百花中的一枝奇葩。之中技术据今已有几千年的历史。锻铜铜雕主要为平面的片活，片活是平装在某些器物上或悬挂起来供人们欣赏。铜铸浮雕制作工艺品的迅猛发展大大丰富了文化项目的内涵，促进了文化产业的繁荣与发展，将让紫铜浮雕像的青铜器一样作为一种文化传承下去。

Forged copper relief (also known as chiseling copper or knocking copper) is a chiseling process based on the ductility of copper materials. It is a wonderful flower in the flowers of traditional handicrafts in China. Technology has a history of thousands of years. Forged copper and bronze carvings are mainly flat pieces, which are paperback mounted on some utensils or hung for people to enjoy. The rapid development of copper cast relief crafts has greatly enriched the connotation of cultural projects, promoted the prosperity and development of cultural industry, and will let the red copper floating statue pass on as a kind of culture like Chinese bronzes.

锻铜浮雕的历史可以说很长远了，早在古代就有了铜雕工艺，浮雕制作的方法其实是很复杂的，一般制作铜雕的方法有：失蜡法，模具法，熔铜法等，一个好的铜雕工艺品要经过很多的程序，经过繁琐的方法。

The history of forged copper relief can be said to be very long. There was a copper carving process as early as ancient China. The method of making relief is actually very complex. The general methods of making copper carving are: wax loss method, mold method, copper melting method, etc. a good copper carving handicraft needs a lot of procedures and cumbersome methods.

我们经常在一些城市里，旅游的景点或者是小区里，甚是学校里见到一些铜雕，铜雕往往起到一个装饰的作用，也代表着某一种精神和意义，铜雕的摆放可以提高城市或者学校的整体形象。

We often see some bronze carvings in some cities, tourist attractions or communities, and even schools. Bronze carvings often play a decorative role and represent a certain spirit and significance. The placement of bronze carvings can improve the overall image of the city or school.
