Lost Wax Casting This refers to the "lost wax" method of "investment casting." For centuries articles of jewelry have been made by a technique that is called lost wax casting. This method is basically done by taking a wax or plastic model and encasing it in a plaster like material called investment. This investment is then heated in an oven to high temperature and the model melts away and evaporates. This is known as the burnout cycle. Once the model is eliminated, metal is melted and "cast" into the cavity where the model once was (hence the name "lost wax"). The metal can be injected into the mold by a number of different techniques (steam, vacuum, centrifugal force, etc.)

1: Put your wax figure in a liquid cast material

2: Make a hard cast of your object 3: Heat to lose wax, create empty space

4: Pour molten metal into cast 5: Let cool, separate mold halves
