Calcined copper relief process

Calcined copper relief process is as follows:

The first step: design drawings

Design sculpture modeling is the first for the sculpture is the overall conception of the design of the drawings, and then in accordance with the pattern of the appearance of this casting casting this bronze sculpture.

The second step: the production of clay draft

Requirements according to the corresponding drawings to make a rough model, the purpose of doing so is to facilitate the stereotypes. Also in order to find imperfections to modify.

The third step: mold turned

Generally speaking, there are two kinds of molds: one is not too complicated, the plaster turned. The other is complex, the mold is made of silicone. Turning the mold is based on the complexity of the work and decide the program, the simpler works can be taken to gypsum turning, the more complex to use silicone turning.

The fourth step: wax filling

After the molds are made, the melted paraffin wax is poured into the plaster molds or silicone molds, and when the paraffin wax is cooled down, the molds are dismantled, and the wax works are formed, which is called "wax filling".

Step 5: Shell making

Similarly, there are two options for shell making, for small or complex pieces, we use delicate quartz sand to wrap the wax model layer by layer, and then burn the paraffin inside the shell with high temperature. The other is the resin sand box production, sand box production is generally applicable to simple, flat relief, large copper coins, copper Buddha's back, such as not much craftsmanship of the glossy surface.

On copper sculpture

Copper sculpture production techniques are generally divided into wrought copper and cast copper, cast copper sculpture: copper as the main raw material, the metal will be melted into a liquid to meet certain requirements and poured into the casting model, after cooling and solidification, finishing treatment to get the casting process with a predetermined shape, size, and performance of the casting process of sculpture works of art.

Forged copper sculpture: forged copper sculpture compared to cast copper sculpture with more stringent materials, copper plate as the main raw material, attached to the steel skeleton support, part of the complexity of the sculpture needs to be made one to one molds for forging, part of the simple modeling can be based on the release of the skeleton forging.
