The position of the notch 9 is provided 0.7 mm below the boundary with the upper part 5. Regarding the size of the notch 9, the diameter a of the boundary with the upper part 5 and the diameter c of the notch 9 are about 5: 1. In this embodiment, a: c = 1.1 mm: 0.2 mm. The size, shape or pattern of the upper part 5 is arbitrary.
[0010]
Next, with reference to FIG. 3, a description will be given of a specific method of manufacturing the above-described decorative article.
<1> Making dough made of precious metal clay First, precious metal clay is put together so as to prevent air from entering, and a dough ball (not shown) is made. In the embodiment, pure silver clay “PMC3” manufactured by Mitsubishi Materials Corporation is used (pretreatment step).
[0011]
<2> Forming step The above-mentioned dough is formed into a predetermined shape. In the embodiment of FIG. 1, after forming the frame-shaped main body 1 as shown in FIG. 3B (first step), it is wound around a round bar (not shown) to form a ring (second step). .
[0012]
<3> Embedding of the decorative element 3 Next, a desired decorative element 3 as shown in FIG. 2 is embedded in the main body 1 as shown in FIG. 3 (C) (third step).
[0013]
<4> Drying Step Next, the process product after the third step is naturally dried for about 1 day or forcibly dried by a dryer or the like for 30 minutes or more (fourth step).
[0014]
<5> Firing Step Next, the processed product after the fourth step is placed in a cylindrical firing pot and fired at about 600 ° C. to 700 ° C. for about 30 minutes (fifth step).
[0015]
<6> Finishing Step Next, the processed product that has passed through the fifth step is polished with sandpaper and mirror-finished (sixth step).
[0016]
FIG. 4 shows a second embodiment of the ornament according to the present invention. In this case, the decorator 3 has an upper part 5 formed in a cup shape and a projection 11 provided at a central part of the lower part 7. In this embodiment, the lower part 7 is formed so as to extend from the entire bottom surface of the cup of the upper part 5. The length of the protrusion 11 is 0.8 mm, and the spread angle α is 40 °. The height d of the cup in the upper part 5 is 0.9 mm, the diameter is 3.4 mm, and the height e of the lower part 7 is 1.1 mm.
[0017]
In the case of FIG. 4, the steps <1> to <6> are the same as in the previous embodiment, and the desired stone 13 is mounted on the cup 5 of the decorator 3 following the finishing step. After mounting, the cover ring 5a formed on the outer periphery of the top of the upper part 5 is bent to prevent the stone 13 from falling off.
[0018]
FIG. 5 shows a third embodiment (a pendant) of an ornament according to the present invention. In this case, the main body 1 is formed as a flat plate. As shown in FIG. 5, the decorator 3 can have the upper part 5 as a letter or numeral surface such as an alphabet.
[0019]
In the case of the pendant, as shown in FIG. 6, the steps up to <1> to <5> (excluding the step of forming a ring) are the same as in the previous embodiment. After the firing step, holes 15 for passing the chains are formed (perforation step). Next, the same finishing step as described above is performed.
[0020]
According to the above embodiment, since the decorator 3 has the upper part 5 and the lower part 7 made of an integral solid noble metal (integralness of the decorator 3), the lower part 7 is detached from the upper part 5 even when heated in the firing step. There is no.
[0021]
Even if the decoration element 3 receives the heating in the firing process, the lower part 7 does not separate from the upper part 5 because the melting temperature of the decoration element 3 is higher than that of the main body 1, so that the decoration element 3 can be fired together with the main body 1. This has the following effects.
[0022]
That is, the lower part 7 is provided with the notch 9 or the protrusion 11 in order to prevent the decorator 3 from dropping from the main body 1. When the decorator 3 is embedded in the main body 1, a gap 12 is formed along the locus of the cutout 9 or the projection 11 (indicated by a dashed line in FIG. 7). However, these voids are filled with a cloth made of pure silver clay due to shrinkage of the main body 1 in the firing step, and fired in this state, so that the decorator 3 is firmly fixed to the main body 1 instead.
[0023]
The body 1 that has undergone the firing step shrinks by about 10% because moisture and the binder are removed. On the other hand, since the decorator 3 is a solid body from the beginning, it does not shrink even after the firing step. Therefore, the lower part 7 (especially the notch 9 or the projection 11) of the decorator 3 bites into the main body 1 and is fixed.
[0024]
The fixing of the decorator 3 to the main body 1 can be performed exclusively by the lower part 7 having the above-mentioned unity. Therefore, the upper part 5 has an aesthetic aspect such as a design or a character, a pattern or the like, or a display of a character or a number. Can be specialized in the field. As a result, the decorator 3 can ensure flexibility in design.
[0025]
For example, there are a design by embedding various decorative elements 3 as shown in FIG. 1, a design in which a jewel 13 is installed as shown in FIG. 4, and a design in which characters are added as shown in FIG. In the case of FIG. 4, it is possible to mount natural stones or beads, which could not be mounted conventionally because of burning in the firing step.
[0026]
The present invention is not limited to the above embodiment. For example, the main body 1 can be processed into various accessories such as accessories such as bracelets, earrings, brooches, necklaces, badges, medals, buckles, tie stoppers, band fasteners, and handles such as knives, forks and spoons.
[0027]
The size or shape of the lower part 7 can be changed as appropriate.
[0028]
The size or installation position of the notch 9 is arbitrary. The shape, size, or installation position of the projection 11 is arbitrary. For example, it may be extended and formed just below the center of the bottom surface of the cup of the upper part 5. Further, the spread angle of the projection 11 can be changed as appropriate.
[0029]
The kind of the noble metal clay is arbitrary. In addition to the silver clay, other noble metal components such as gold clay and brass clay may be used. The purity of the noble metal is arbitrary and need not be 100%.
[0030]
Further, the main body 1 and the decorator 3 may not necessarily be the same noble metal. For example, the decorator 3 made of solid gold may be embedded and fixed in the main body 1 made of pure silver clay.
[0031]
【The invention's effect】
As described above, according to the present invention, since the decorator is integrated and the decorator 3 can be fired together with the main body 1, detachment of the decorator can be prevented, and a variety of handmade ornaments can be easily and reliably manufactured. , And can be differentiated from the ornaments of others.
