Wrought copper process
2021-12-06
Wrought copper is a process different from cast copper. It is created on a copper plate. The texture of the copper plate becomes soft after heating, and the hardness is restored after hammering. Repeat this process to finally produce wrought copper reliefs and wrought copper Sculptures and other round-carving works of art or other daily and industrial products. With the improvement of people's living standards and aesthetic appeal, the traditional craft of forging copper is especially popular among designers and the public in the arts and crafts field.
Fire, hammer and chisel are the three important elements of wrought copper.
Small-scale copper-forged work or partial processing of large-scale copper-forged works can be heated by high temperature generated by oxygen and acetylene, while large-scale works need to be heated by blast furnace fire. This part of heating is relatively easy. The heated copper plate should be flattened with a leather hammer. Appropriate proportion of rosin and soil and other raw materials are melted in a container, and then poured into a workbench with a 3-5 cm high edge around it to fix the heated copper plate. This method is stronger and stronger than the original sandbag method. The hammer chisel feels good.
The use of hammers and chisel is the key to the whole copper forging process, which is the reason why "forged copper" is also called "hardened copper". Every copper forging master has hundreds of chisels of various forms in his hands. Using these chisels to outline the ups and downs on the copper plate is called "wiring". It will take several years to quickly and accurately route the wires according to the drawings. Kung fu, especially some key parts, such as the facial features of the characters. Large-scale copper forging works require the cooperation and collective creation of multiple copper forging craftsmen. Some processes require the cooperation of the craftsmen to be very tacit. For example, sometimes it is necessary to hang the copper plate. The staggered lines reach perfection.

After the work is welded and assembled, polished, planed, or aged and painted, a wrought copper work is completed.
