摘要
PROBLEM TO BE SOLVED: To provide a method for producing a memento which has a high value as the memento for thinking of a dead person by using, as a material, a dental metal which has been discarded together with residual bone ash after the cremation of a dead body without being removed from the dead body in many cases though it has a value as a noble metal.;SOLUTION: A dental metal mixed and remaining in residual bone ash is extracted, and the same is sorted into noble metal and non-noble metal. A wax pattern is made, and the wax pattern is fixed to a conical stand for dental casting via a sprue line. A ring for casting is mounted on the conical stand, the inside of the ring for casting is filled with a burying material to bury the wax pattern, and after the burying material is solidified, the conical stand and sprue line are removed to form a sprue and a runner. The same is heated by an electric furnace to burn the wax pattern, thus a cavity is formed into a mold. The dental metal is heated and melted to be cast into the mold, the burying material is removed from the produced cast body, and a memento is separated from the cast body and is subjected to surface-finishing.;COPYRIGHT: (C)2012,JPO&INPIT
