Lost Wax Method for Small Bronze Sculpture
Overview of methods: (very broad)
1. model and shape microcrystalline wax to ideal form of finished project
2. attach pour cups to the project
3. dip wax piece in alternating fixing agent and silicone sands
4. fire ceramic shell, removing wax from mould
5. heat and pour molten bronze into the shell
6. after cooling, break away ceramic shell, cut off pour cup
7. polish, patina, and display bronze piece
This documentation has taken into account the materials and facilities required to prepare and pour bronze castings. Due to the hazards involved with this process, all work is to be done in a qualified lab or similar art studio setting. Extra caution should be taken during ceramic shell formation, burn- out, and pouring of molten bronze (forging). Respirators, fire suits, fire tongs, gloves, leather boots, and eyeware are required in combinations.
