When looking at a piece of jewelry, there are some people who don’t only admire their beauty and style, but also wonder how they are made. Jewelry is made using different methods. However the most commonly used method is lost wax casting method. This first evolved in the ancient times and is used until today though there are already modern tools that are available.
The main reason why this method is popular then and now is because with the lost wax, that is to be made is initially sculpted out of the wax to the accurate specifications of what the finished product will look like. After completing the wax sculpture, it will then be encased in the silica encasement or the jewelry case before it is encased in plaster. After the encasement is hardened and dried, it will be placed into an oven. This will allow the wax to melt down and burn out which leave a hollow image within the encasement of plaster.
The plaster encasement with the hollow shape of the jewelry piece is put into the casting centrifuge. It is a device that utilizes centrifugal force to drive the molten gold down through the opening in the chunk of plaster. It will fill in the hollow spot left by the wax to melt out. After cooling down the plaster, it is broken open to reveal the piece of gold jewelry where the sculpture of the wax was placed once.
It is the same technique utilized to create the bronze sculptures that are much bigger. However, with bronze, it is done on larger scale and it does not use centrifugal caster. The method of lost wax casting was used to bring civilization out of Iron Age into the Bronze Age.
Jewelry making is a complicated process. It has to be done with someone that is skilled and knowledgeable in crafting jewelry. It requires expertise, even to the smallest piece of jewelry. If you love jewelry, it does not necessarily mean that you will make one on your own. You can show appreciation to jewelry by buying or wearing them.
