Metal Casting. This is an overview of the process that I went through while developing a successful sword casting technique. It was very difficult to cast a bronze sword because the blade is so thin. My best attempt is shown as "Refractory Cement attempt #3" at 4:51. I buried a two part mold made from "Ruttland Castable Refractory Cement" in sand. I made the mold by creating a sword shaped impression in one half with a wooden model. After that half cured I sprayed the surface with Pam (to act as a release agent) and then built the second half of the mold on top. The Pam allowed the cement to be separable and also form perfectly matching surfaces. This mold is also the same mold shown in "Refractory Cement attempt #1" at 1:11.
**It is imperative to understand that molten metal will create steam explosions when it comes into contact with both Plaster of Paris, Refractory Cement and any other material that contains water by nature. I did some ignorant stuff but got away with it.
