SHAPE-CHANGING ORNAMENT

PURPOSE:To obtain an interesting ornament which shape changes due to heat by providing a base of such a constitution that a split mold into which a molten material is poured, is formed at the bottom of the base, and an injection port through which a molten material is injected, and an inclined surface formed to the injection part from a periphery are provided. CONSTITUTION:A base 3 on which a molded product is placed is composed of a positive form 3b and a negative form 3a, and is provided with an injection port 3c for injecting a molten material into the forms 3a, 3b and an inclined surface 3d toward the injection port 3c from a periphery, on the top. Consequently, wax melts and runs out by heating the molded product externally and a core 2 is exposed from the interior. This molten material that runs out is poured into the forms 3a, 3b from the injection port 3c, flowing along the inclined surface 3d. After this, when the molten material cures, it is split into the negative form 3a and the positive form 3b, and a new molded product 5 is formed from the inside.
