た。However, in general, the glaze has poor wettability with respect to the metal surface, and the colored portion obtained by firing is not sufficiently adherent to the metal surface, and therefore is sometimes peeled off in the final polishing step. In some cases, if the colored portion is peeled off, it has no value as an ornamental product or an arts and crafts product, so it must be discarded or recycled. In particular, when the substrate is made of a noble metal, a great loss occurs. In addition, when the glaze baking surface of the precious metal ornament base or arts and crafts base is smooth and vertical, when you try to draw a pattern or picture with the glaze, it drops and you cannot draw the pattern or picture as you want There was such a problem.

製造することができるという知見を得たのである。Means for Solving the Problems Accordingly, the present inventors have:
From such a viewpoint, it is easy to draw a pattern or a picture with a glaze, and as a result of conducting research to produce a precious metal ornament or an art craft without the baked glaze peeling off in the polishing process, the precious metal ornament base or If the base of arts and crafts is made of a porous precious metal sintered body, and the surface of this porous precious metal sintered body is coated with glaze and then fired, the colored part obtained has excellent adhesion and fails during painting. It has been found that the glaze can be applied without the use of the glaze, and the glaze-baked precious metal ornaments or arts and crafts can be produced without peeling in the finish polishing step.

The present invention is characterized by a method for producing a colored precious metal sintered body in which a surface of a porous precious metal sintered body substrate is coated with glaze and then fired.

よるものであると考えられる。When the glaze-baked precious metal sintered body of the present invention is manufactured, the colored portion does not peel off in the finishing surface polishing step because part of the colored portion penetrates into the pores of the porous precious metal sintered body. It is considered that the colored part is firmly adhered to the precious metal sintered body due to the anchor effect, and the glaze does not hang down during painting, and the reason why it does not fail is that the density ratio is 60-95% It is considered that this is because a part of the glaze is absorbed by the porous precious metal sintered body substrate by the porous precious metal sintered substrate.

By forming a heart-shaped molded body from a noble metal molding plastic composition containing t% and the balance being water and unavoidable impurities, the molded body is fired in an electric furnace at 900 ° C. for 2 hours. A pure silver porous sintered substrate was prepared. A glaze-baked precious metal sintered body of the present invention having a colored portion is produced by applying a glaze to the surface of this pure silver porous sintered base and firing it in an electric furnace at 800 ° C. for 10 minutes. When the surface of the glaze-baked precious metal sintered body of the present invention was barrel-polished and a mirror finish was tried, no peeling occurred in the colored portion.

A heart-shaped molded body is made of a noble metal molding plastic composition containing 0.5 wt% and the balance of water and unavoidable impurities, and the molded body is fired in an electric furnace at 1600 ° C. for 2 hours. Thus, a pure platinum porous sintered substrate was produced. A glaze-baked precious metal sintered body of the present invention having a colored portion is manufactured by applying a glaze on the surface of this pure platinum porous sintered substrate and firing it in an electric furnace at 1280 ° C. for 10 minutes. When the surface of this glaze-baked precious metal sintered body of the present invention was barrel-polished and a mirror finish was tried,
No peeling occurred in the colored part.
