PROBLEM TO BE SOLVED: To secure required performance and at the same time promote decrease in waste by containing larger amount of reproduction material of crucible and a crucible stand with an inner surface for dividing a recessed part that opposes the bottom portion of the crucible being heated from the outside by a heating means and an outer surface whose rear surfaces opposes the inner surface. SOLUTION: A crucible stand 1 is provided with an inner surface 11 for dividing a recessed part 10 of a recess that opposes an area near a bottom part 2x of a pot 2 for accommodating molten metal, and an outer surface 12 whose rear surface opposes the inner surface 11. Also, the crucible stand 1 is in a cylindrical shape and is provided with an inner-layer 13 at a side close to the inner surface 11 and an outer-layer 14 at a side close to the outer surface 12. Then, the inner-layer 13 is formed with a reproduction material based on waste as a main body. On the other hand, the outer- layer 14 is formed with a newly produced material as a main body. As a result, by forming the crucible stand with a material containing more newly generated material, the practical performance of the crucible stand can be secured. On the other hand, at the inner surface side where usage environmental conditions are not strict so much, the waste is reutilized by formation with the reproduction material based on the waste of the crucible and the crucible stand.
