The main difference between wrought bronze sculpture and cast bronze sculpture lies in the difference in processing technology.
Wrought bronze is to heat the copper sheet, using the ductility of the metal, and knock the copper sheet with a tool.
The casting of bronze is done by first making a wax mold, and then pouring bronze water into the mold and cooling it.
Wrought bronze sculptures mainly consist of forging. The sculptures are formed by extrusion under the action of high temperatures. Wrought bronze sculptures have the effect of refining crystal grains. Wrought bronze sculptures are forged and trimmed by hand according to the remanufactured sculpture molds. Most of them are copper plates. The copper plates of the forged bronze sculpture are combined into the overall finished product of the sculpture.
The characteristics of wrought bronze sculptures are generally good in color and gloss, strong modernity, strong expressiveness, and there is no size limit. The disadvantages of wrought bronze sculptures are not suitable for sculptures that require too many details, such as specific portrait sculptures.
Cast bronze sculptures are made by filling the cavity after melting the bronze, and then form the bronze statue firmware after the melted bronze cools; the cast bronze sculptures are generally formed by one-to-one casting. The characteristics of the cast bronze sculptures are strong artistic expression, high texture, and long preservation time.
These two kinds of sculptures of different crafts are suitable for different design patterns, which should be selected according to budget, style, and environment.
