Lost wax casting is a technology that has been in existence for a very long time. Wax can be made at home in order to cast jewelry. To carry out lost wax casting, a wax model needs to be created. To do this, you need special wax, some simple tools and a heat source. It is possible for you to get hard wax and carve it, or soft wax that can be easily manipulated with the fingers. Several other models can be made and attached to form a wax mold tree. Once the wax model is made, it is placed in a flask for further casting processes.
