Abstract

PURPOSE:To improve the added value of the title object by heating a raw gold material of a specified shape at a temp. above the recrystallization temp., and etching the material with aqua regia to render an aesthetic design to the material. CONSTITUTION:The raw gold material 3 is formed, for example, in the specified shape in a pendant as a personal ornament of craftwork. The material 3 is heated, for example, at 800-1,000 deg.C which is higher than the recrystallization temp. of gold, and then etched with aqua regia. As a result, the grain boundary 7 rises completely to the surface 6 of the material, and Gothic or arabesque design is formed on the whole surface as an inlaid pattern. Consequently, a heavy gem-like image, a so-called quiet feeling as if fumigated, is provided to the material 3 instead of the smooth, planar, and lustrous gold in addition to the splendid aspect of the noble metal. As a result, the added value of the product 4 as a commodity can be enhanced.

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology has market value as a base metal, while giving a fashionable jewel-like image to decorative crafts such as pendants and ornaments. It belongs to the technical field of structures designed to increase added value.

<Summary of the gist> Therefore, this invention applies physical and chemical processing to a gold material in a predetermined shape for coin bars, pendants, etc. and embeds it in pendants, coins, shields, etc. to make ornaments, etc. This invention relates to crafts, and in particular, a gold material of a predetermined shape is heat-treated at a high temperature of 800 to 1000 degrees Celsius, above its recrystallization temperature, and then etched with aqua regia to form a Gothic pattern on its surface. This invention relates to decorative gold crafts that are provided with aesthetic pattern structures such as the above.

<Prior art> As is well known, gold or gold bullion has fundamental economic importance, is traded as a useful material as a basic material, and has been a stable material and currency for many years. It has long been considered a subject of personal deeds due to the implication that it is an asset.

Recently, due to its property value, it has become pervasive in people's lives, and it has come to be distributed among general consumers in the form of so-called coin bars, coins, or medals.
In some forms, it is beginning to spread to accessories such as pendants and crafts such as ornaments.

<Problems to be solved by the invention> In the market for nuclide ornaments, crafts, etc., the shape of the products in the transaction is almost constant, and there are many products that have no added value other than that. For example, in the case where a gold product is used as the pendant 1 as shown in Figure 3, the color tone is only the smooth hue characteristic of so-called golden gold, and the frame 2 is only formed. Therefore, although it is satisfying to purchase gold for asset preservation, as mentioned above, the aesthetic design of gold when used for decorative crafts such as pendants, coins, and figurines is lacking. There is a limit, and it is difficult to arouse the desire to purchase.Also, even on the supply side, only the property value is exposed, so competitiveness cannot be gained, and the advertising power of the mass media etc. and mere capital. The problem was that they only competed based on market share based on force, and distribution was not activated.

<Purpose of the Invention> The purpose of this invention is to solve the technical problem of the lack of design of gold products as objects of asset preservation in ordinary citizen's life based on the above-mentioned prior art, and to In addition to retaining value, we aim to improve the image of precious metals as jewels, increase added value, revitalize distribution, create a luxurious mood, and apply design technology in the distribution industry. We aim to provide excellent gold decorative crafts that will benefit the public.

<Means/effects for solving the problems> In order to solve the above-mentioned problems, the structure of the present invention, which is summarized in the above-mentioned claims in accordance with the above-mentioned object, is a device formed into a predetermined shape such as a pendant or a coin. The temperature of the gold material is above its recrystallization temperature a
It is treated at a high temperature of 1,000°C or higher, for example, to make the face-centered cubic lattice grain boundary structure stand out on its surface in a gorgeous gothic or arabesque pattern, creating visually luxurious jewelry. We have taken technical measures to give decorative crafts the precious metal atmosphere that gives them the image of a precious metal, retain their asset value over time without losing their value, and to add aesthetic design to decorative crafts. It is something.

<Embodiment> Next, one embodiment of the present invention will be described below based on FIG. 1.2. Note that the same parts as in FIG. 3 will be explained using the same reference numerals.

The illustrated embodiment is a pendant used as an accessory for decorative crafts, and the gold material 3 has a pendant 4 whose outer shape is shown in FIG.
to a predetermined thickness as shown,
It has a predetermined square size, and a hook 5 for passing a chain through is integrally formed on one side of the square.

When forming the pendant 4 of the product, the gold material 3 is
However, at a temperature higher than the recrystallization temperature of gold, e.g. 800℃~
It is heated to a high temperature of 1000°C, and then etched with aqua regia.

As a result, the grain boundaries 7 are raised all over the surface 6, forming a pattern inlaid with Gothic type or arabesque type patterns, which is commonly called a gold color instead of the smooth all-over luster of the gold material 3. It gives the impression of a heavy, smoked jewel with a somber feel, giving it the luxurious appearance of precious metals.

Therefore, by using such a pendant as an accessory, the owner can obtain the same satisfaction as a gemstone that has an exceptionally fashionable color tone and deep shine unique to the owner, and is a rare and valuable gemstone. It is possible to create an image that the product has, and it is possible to sufficiently increase the added value in terms of handling of the product.

Of course, there is the added value of accessories such as pendants, and the asset value of gold is not affected by the above-mentioned high-temperature heat treatment or etching treatment, so there is no loss of wealth. There are no disadvantages.

Since the gold material 3 is chemically stable, it is stable against sweat and environmental atmosphere.
As described above, the crystal grain boundaries 7 formed on the surface 6 of the pendant 4 do not disappear or fade even when worn as an accessory, and from this point of view, the precious metal becomes more like a jewel over time.
