Copper sculpture is a very old art form and in the Americasit can be traced back to Purepecha Indians of Central Mexico. The first shapingof copper was done to create farming and domestic implements and weapons byhammering copper ingots into shape. Modern copper sculptures are created using techniques andtechnology far advanced from the beginnings of the art form. While manytechnologies may be used, the most common and popular is to creates a sculptureby shaping separate pieces of copper sheeting then weld them together. Thisallows the sculptor to produce as large a piece as he desires. The process begins with the forming of the copper sheetsinto bowl shapes. This allows the sculptor to then heat the forms and hammerthem into the rough desired shape. If gaps appear in the metal during theshaping process, these are filed using welding rods. The artist usually workswith a paper pattern to guide him in both the initial sheet metal cuttingprocess and well as in the shaping. Most artists making copper sculptures donot use highly detailed sketches, but rather rougher free hand drawings so theif, in the process of shaping the metal, the emerging shapes offer newopportunities, he can quickly modify the sketch to have an idea of the endresult of any mid course changes. The individual parts are worked on till they take theirfinal shape. Any rework after the welding is done may damage the welds. Anysurface irregularities are removed by hammering with a unique rocking motionthat allows the indents on the surface to be either raised or lowered. Before the welding begins, the final finish is applied tothe individual pieces. The color options are chocolate brown, wine read,running black streaks and the standard bright polished finish. Since the finishis given to individual pieces one at a time in the forge, the final patinaswill always have small variances. If he so desires the artist can remove thenatural patina through buffing and leave behind the shiny surface. A piece ofcopper sculpture with a shiny finish will require regular polishing to maintainthe shine. The artist may add silver decoration to the copper sculptureby etching a design on the surface to the shaped pieces and dipping them intoan electrically charged bath which fuses the two metals together. Coppersculptures are often given a clear lacquer finish to protect the metal from theelements. Once all the pieces are complete in every details, thewelding process begins. In the case of copper this is usually done by a processcalled tig welding where a filler rod is heated by tungsten gas to fix thepieces in place. Copper sculpture is suitable for both indoor andoutdoor use. Copper is a favorite material of artists who specialize in modernor abstract art. Except in the case of sculptures with a polished finish,copper sculpture requires no maintenance except for a simple dusting or wipedown with a damp cloth. The use of cleaning agents is not recommended as theymay affect the finish of the metal.
