Bronze Casting is a procedure in which a malleable liquid metal is fed
In ancient times, bronze casting was used to manufacture swords, weapons, armor, and other metallic objects. Bronze has been in use since ancient days. Bronze Casting is a procedure in which a malleable liquid metal is fed into a mould which contains a side-on impression of the desired shape. The metal, initially molten in the mould, is poured slowly into the mould through a hollow cone-shaped channel called a spout.
The metal and mould are then carefully cooled, and finally the metal component is removed from the mould. The cooling process causes the metal to solidify, thus turning the resulting alloy into a solid form. Prior to casting, the alloy must be prepared for inclusion into molds by heating it in an iron kiln at high temperatures. This rapidly heats the steel rods or pieces to more than 1700 degrees Celsius.
Castings from bronze can be reused hundreds of times
As they are strong, ductile and robust. Bronze is an exceptionally hard, ductile and pliable alloy. This makes it suitable for use in all kinds of metalwork, whether it’s making knives, swords, armor, cannons or even toys. Bronze Casting creates decorative objects as well, such as toys, statues, ceramic mugs and bowls.
The process begins with the forming of a blank into which the metal will be poured. A piece of brass or copper tube, called a kick rod is inserted into the blank. This serves to control the amount of molten bronze flowing through the tool’s tip. A piece of thin stainless steel wire is inserted into the ceramic mold from the back of the kick rod, cooling the wire and allowing it to enter the mould around the edge. After this, the mould is opened and a piece of clay plaster, called a stencil, is placed on the underside of the bronze piece to hold it in place.
The shape of the cast sculpture depends entirely on the artist’s imagination
At this point, it’s crucial that the sculptor’s idea of what the piece should look like coincides with the dimensions of the mould that he has formed. If the dimensions are too small, then the piece would be unstable and prone to falling apart. On the other hand, if the measurements are too large, the shape may not be wide enough or deep enough. A professional artist will listen to the client’s ideas and take note of what he thinks will be the most appealing effect of his bronze sculpture.
Once the design is finalized, the artist begins to make the bronze pieces. Bronze casting begins by pouring a single sheet of metal into the mould from which the finished piece will be made. One by one, individual spruces of metal are melted and added to the molten metal until the piece forms into the desired shape. Once the spruces cool, they are removed and the cooled piece is further melted and shaped until it fits into the mould from which it was created. This entire process takes about three weeks to complete. Once the piece has cooled completely, it is ready to be shipped to clients.
