Copper relief metal sculptures is created on the copper plate. For a custom copper relief, we need a primary design draft. The design draft is required to be a line draft, clear and coherent, which are the critical lines for completed copper relief. The quality of the design draft largely determines the shape of the finished forged copper. For the forging materials. We need 1.2 mm thick copper plate. The copper plate’s ductility and softness are more suitable for forging. The thickness of the metal copper board is determined by the size of the work, and the large piece is made of a thin plate with a small work.
The forging tools are mainly tweezers, hammers, fire, and rosin. The hammer is a normal hammer. The fire is oxygen and acetylene high temperature, used for heating annealing of copper plates. The cement is made of a mixture of rosin and asphalt, and is used as a liner for forging.
Here are the steps to make a copper relief large mural statue. Annealing the copper plate in order to increase the toughness of the copper plate; Cool with water and lay aside for airing and cooling; Paste the design drawings that need to be made onto the copper plate, and use glue and tape. The beginning of engraving with the dice directly along the manuscript to create the outline, and then according to the designer’s ideas, forging rough ups and downs. Re-engraving, reverse the copper plate and then engraved. Leveling, in the detailed processing stage, repeated positive and negative beats, including the processing of texture. Wet acid cleaning, coloring, after the forging is completed, the copper plate needs to be cleaned. Wash with weak acid and rinse with water. Brushed cloth is hand-polished, and finally waxed or sprayed with clear paint as a protective layer.
