Bronze Sculpture - From Molding To Finishing

When it comes to the full size bronze sculpture creation, the Lost Wax Method is the first to be acknowledged. The next step is the cast for the mold that is a hollow wax sculpture. The addition of several wax sprues help in infusing the molten metal into the large life-size sculptures. With the larger bronze sculptures, there may be extra sprues positioned upward within certain critical positions. When the casting metal is finally cooled, the ceramic outer mold is chipped away for the end result of the bronze sculpture to be smoothed and polished.

Bronze has long played numerous roles in the many historical cultures of the past. From the Greek to the Chinese, there has always been a prominent place for bronze sculptures in a wide variety of inner cultural connections. All though several cultures before the Greek are known to have made many small display sculptures, archaeological discoveries have yielded that the Greek civilization was the first civilization to create the original life-size bronze sculptures as known to us today.

When it comes to the full size bronze sculpture creation, the Lost Wax Method is the first to be acknowledged. In the method of lost-cast or also known as the investment casting method, to create a life sized model which is made out of an oil-based, clay substance that would not dry out while working with it. There are several ways to make the original mold from the pattern of oil based clay. There may be a flexible rubber or gel like material, or maybe a mold piece from the plaster created of several pieces of a preservation of the artwork may be made, called a 'plaster master'. A plaster mold may be held until the final decision is made to finish the project at hand. Because these life-size projects made of bronze are so expensive, these plaster molds are the best ways to hold the artistic creation until the funds are cleared for completion.

The next step is the cast for the mold that is a hollow wax sculpture. The hollow sculpture is to have a core put into the hollow area, and is kept within the proper location by metal pins. The addition of several wax sprues help in infusing the molten metal into the large life-size sculptures. The molten bronze metal is slowly poured from the bottom up so not to have any undesired splashing. With the larger bronze sculptures, there may be extra sprues positioned upward within certain critical positions. At this time there may be extra ventilations added when and were needed, so there can be release of gases that could be otherwise trapped.

At this point the wax structure is invested in a different mold to be heated until the wax melts completely away. The shell that is left is what the molten bronze is put into for the final process. When the casting metal is finally cooled, the ceramic outer mold is chipped away for the end result of the bronze sculpture to be smoothed and polished.
