The second method was hollow lost-wax casting, which was created by a direct process. Finally, the third was hollow lost-wax casting by an indirect process. The model is packed in clay, and then heated in what today would be similar to a kiln to remove the wax and harden the clay. Then, the mold is inverted and metal poured inside it to create ...

Lost-foam casting. Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.
