The cold crucible is a tool which is frequently used for induction heating applications for the elaboration of materials by middle or high frequency magnetic field. This crucible is made of copper sectors assembled together to form the container in which the electroconductive material is molten. Each sector is water cooled, which keeps the crucible cold when the material is heated and molten inside it thanks to the induced currents produced by a surrounding inductor.
