The present invention relates to apparatuses for preparing a crystal of the cremated remains which use a gas furnace, an electric furnace and a high-frequency furnace. One method for preparing a crystal of the cremated remains comprises the steps of compounding powder of the cremated remains and a mixture of minerals, kneading the compound, heating and melting the kneaded matter, preparing the melted matter into a crystal having a granular shape, and processing a heat treatment of the prepared crystal. Another method for preparing a crystal of the cremated remains comprises the steps of putting powder of the cremated remains into a pot crucible, heating and melting the powder in a pot crucible in the range of 1500 DEG C to 3500 DEG C, dropping the melted matter through a discharge hole of a pot crucible to the inclined passageway, preparing a crystal having a granular shape at atmosphere as rolling the cooled matter through the passageway, and processing a cooling treatment in ceramic powder container. |
