Abstract

PROBLEM TO BE SOLVED: To provide silver clays, the kind of which used during molding by a molder can be always grasped without hesitating, and its wrapping body. SOLUTION: The kinds of silver clays can be discriminated by pasting golden gold foils 5 or/and gold dust on at least surface of a white silver clay lump 11 and by its wrapping body, by which the kind of the sliver clay is discriminated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver clay having a golden clay or a gold powder attached to at least the surface of a white silver clay mass so that the type of the silver clay can be identified. The present invention relates to a package and a method for identifying the type of silver clay, and is intended to allow the author to always know the type of silver clay used during modeling.

2. Description of the Related Art In the field of arts and crafts and hobbies, precious metal clays are used to easily create shapes by freely shaping the shape imagined by free thinking, and easily burn arts and crafts and decorations by baking these shapes. Silver clay is widely used because of its ability to make goods and the like, and silver clay is most widely used because of its relatively low price. As shown in the cross-sectional view (a) of FIG. 4, this silver clay is generally commercially available as a package 4 in which a silver clay mass 1 is wrapped in a transparent wrap film 2 such as a plastic bag. When using the silver clay, as shown in the cross-sectional view (b) of FIG.
Then, as shown in the cross-sectional view (c) of FIG.

A package 4 of a silver clay mass 1 wrapped in a wrap film 2 shown in a sectional view (a) of FIG. 4 is housed in a container 3 as shown in a perspective view of FIG. And sold. In recent years, not only one kind of silver clay, which is sold in the container 3, but several kinds of silver clay having different characteristics are arranged and sold as a set. For example, FIG.
As shown in the perspective view of FIG. 1, a package 41 of a silver clay lump to which ordinary pure silver powder is added, a package 42 of a silver clay lump to which a relatively small amount of pure silver powder is added to obtain a porous sintered body, In order to obtain a sintered body, a package of silver clay mass 43 to which a relatively large amount of pure silver powder is added is stored in the container 3 and is sold as a set. Then, the desired shaped body is finished and fired to produce arts and crafts, ornaments and the like.

[0004]

During the molding operation, the wrapping film of the package is peeled off and the silver clay mass is taken out.
Since the colors of silver clay are all white, sculptors may not be able to tell what kind of silver clay is currently being used for modeling. For example, when the silver clay mass is taken out from the silver clay mass packaging bodies 41, 42, and 43 shown in FIG. 5 and molded using three types of clay, the color of the silver clay is all white. The silver clay used in the method may be indistinguishable from what kind of silver clay it has.

In order to solve these problems, it is conceivable to add color to silver clay. However, colored silver clay is preferred because pigments attached to the hands during molding adhere to other silver clay. It is not preferable because the color may remain even after firing.

[0006]

Means for Solving the Problems Accordingly, the present inventors have
As a result of studying to solve these problems, (a) the gold foil 5 is stuck on the surface of the silver clay mass 11 as shown in the plan view of FIG. If the gold powder 6 is pasted on the surface of the lump 12 or the gold foil 5 and the gold powder 6 are pasted on the surface of the silver clay lump 13 as shown in the plan view of FIG. In addition to increasing the feeling, it is possible to understand the type of silver clay lumps to be used even after the wrap film has been peeled off, and to identify the type of remaining silver clay lumps during molding work. (B) The silver clay in which gold foil and / or gold powder is adhered to the surface of the silver clay mass does not affect the sintering characteristics of silver clay since the amount of gold foil and / or gold powder is extremely small. Sintering clay shaped objects Gold leaf and / or gold powder also it does not impair the color tone that has been absorbed into the matrix during the sintering of the silver,
The knowledge was obtained.

[0007] The present invention has been made based on such knowledge, and (1) silver clay having gold foil adhered to at least the surface of a silver clay mass, and (2) gold powder applied to at least the surface of the silver clay mass. And (3) silver clay in which gold foil and gold powder are adhered to at least the surface of the silver clay mass.

[0008] Even if the metal foil and / or powder applied to at least the surface of the silver clay mass is a colored metal such as copper foil and / or copper powder, the type of silver clay can be identified, Metal foils and metal powders that are easily oxidized or / and sulfated like copper are not preferred because they change color by being oxidized or / and sulfated during long-term storage. Further, the use of copper foil and / or copper powder is not preferable because it gives the impression that a work containing impurities is produced due to the incorporation of a metal that is less expensive than silver, and the sense of quality is impaired. On the other hand, gold foil and / or gold powder is preferable because it gives a higher quality than silver.

The gold foil and / or gold powder may be buried in the silver clay mass, but in such a case, it is necessary that the gold foil and / or gold powder is adhered to at least the surface. This is because the presence of the gold foil and / or the gold powder on at least the surface of the silver clay mass enables identification.
The amount of gold foil and / or gold powder to be attached to at least the surface of the silver clay mass may be large, but it is only costly and there is no difference in discrimination ability. Therefore,
The gold foil attached to at least the surface of the silver clay mass may be as thin as possible as long as it can be identified, and the gold powder may be as small as possible.

[0010] The silver clay of the present invention in which gold foil and / or gold powder is adhered to at least the surface of the silver clay mass is sprinkled with at least the surface of the silver clay mass with the gold foil and / or gold powder, and is gently pressed down. Gold leaf or /
And gold powder can be produced. The gold foil to be stuck to at least the surface of the silver clay mass may be any scaly gold foil, but may be a gold foil cut into a star shape or the like. Further, the identification method of the present invention can also be carried out depending on the number of gold foils attached, the distribution state of gold powder, and the like. The silver clay produced in this way is shown in FIG.
As shown in (a), it is wrapped with a transparent wrap film and stored or sold as a package in the same manner as before.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION A silver clay mass 11 containing pure silver powder having an average particle size of normal size: 20 μm, a silver clay mass 12 containing pure silver powder having an average particle size of more than 60 μm, and usually Average particle size of finer particle size: 5 μm
A silver clay mass 13 containing pure silver powder was prepared. On the surface of the silver clay mass 11, as shown in FIG.
The silver clay 1 of the present invention can be obtained by attaching a gold foil piece 5 of μm.
Was prepared. As shown in FIG. 2, a silver clay 2 of the present invention was prepared by adhering gold powder 6 having an average particle size of 6 μm to the surface of the silver clay mass 12. Further, as shown in FIG. 3, the thickness of the silver clay mass 13 is 0.1
The silver clay 3 of the present invention was produced by attaching a gold foil piece 5 of μm and a gold powder 6 of average particle size: 6 μm.

The silver clays 1 to 3 of the present invention are wrapped with a wrap film to prepare a package. After one year, the wrap film of the package is removed to remove the silver clay masses 11 to 13. / And the type of the silver clay mass could be identified by the gold powder, and the type of the silver clay mass could not be identified during the modeling operation.

[0013]

As described above, when the silver clay of the present invention is used, it is possible to form a molding at a different place of a molded body with a type of silver clay suitable for the place without being lost. It has an excellent effect that silver clay can be used efficiently and effectively.
