Description

[Detailed description of the device] [Industrial applications]

The present invention relates to improvement of earrings, and more particularly, to ceramic earrings produced by firing clay.

[Prior art]

Heretofore, earrings have been manufactured by using jewels that are made by processing metal materials such as gold, silver and platinum into various shapes or polishing them. This earring has the drawback of being expensive in material. Further, the metal earring has a defect that the surface is scratched and loses its gloss as it is used. As a substitute for these materials, various ceramic earrings have been developed that can be manufactured at low cost (Japanese Patent Publication No. 62-2157). The jewelry such as earrings described in this publication is obtained by firing alumina into a plate shape and providing a coloring layer with a coloring agent and a flux on the surface thereof.

[Problems to be solved by the device]

The earring described in this publication has a feature that the material cost can be remarkably reduced as compared with jewelry or the like. Further, since it is made of a ceramic produced by firing, it has excellent weather resistance, and has the features that the surface is hard and is not easily scratched. However, the accessory of this shape cannot have an appearance similar to that of a jewel, and cannot wipe off the image of an industrially mass-produced product. The reason is that, in addition to the plate-like outer shape, the surface is painted and decorated. For this reason, there is a drawback in that it is not possible to realize an earring with a beautiful appearance similar to that of jewelry, and it is impossible to manufacture a high-quality earring. In addition, since the surface of the ceramic plate fired in a plate shape is painted, there is a drawback that the manufacturing process is troublesome and the manufacturing cost is high. This invention was developed with the aim of solving this drawback, and the important purpose of this invention is to use inexpensive raw materials, to make it simple and easy, yet to be weather-resistant and natural. The aim is to provide earrings that can be mass-produced at a low cost in a very beautiful way, which is very similar to the jewelry of.

[Means for solving the problem]

The earring of the present invention has the following structure in order to achieve the above object. The earring includes a decorative body and a fixing metal fitting. The decorative body is made of ceramic by firing an inorganic material. Furthermore, the earring of the present invention is characterized by having the following configuration. (A) The decorative body 2 is a fired product formed of clay into a three-dimensional shape with a convex center. (B) The decorative body 2 is coated with glaze on the surface thereof, and is provided with the gloss layer 5 in which the central portion and the outer peripheral portion are gradually colored in different colors by allowing the glaze to flow down to the outer peripheral portion by its own weight.

[Action]

The earrings of this invention can be colored in extremely beautiful colors. To achieve this, the earring of the present invention is manufactured as follows. Clay is molded into a three-dimensional shape with a convex center and dried until the moisture content is 2% or less. The dried molded product is fired to form a unglazed body. The firing temperature is 800 ° C to 1300 ° C. Place the unglazed base on a horizontal table, apply glaze on the top and dry. The dried base material is loaded horizontally into the firing furnace in a horizontal posture, that is, with the central convex portion facing upward. Bake to dissolve the glaze and let it flow down under its own weight. The glaze that melts and flows down has a light color at the upper end and a dark color at the lower part. Further, since the color flows down due to its own weight and the upper part and the lower part have different colors, there is a natural density difference between the colors. As described above, after the body is bisqued, the glaze can be applied and fired again, but it is also possible to mold the clay and apply the glaze to the dried body, and then fire it to obtain a decorative body. The decorative body completed in this state is fixed to the fixing member using an adhesive or using a screw. The earring of the present invention manufactured in this state can color the ornament in a beautiful color pattern that is as good as that of natural jewelry. This is because the decorative body is formed into a mountain shape with a convex center, and the glaze applied to the upper part is naturally allowed to flow down in a molten state so that the upper part and the lower part have a natural difference in concentration.

【Example】

An embodiment of the present invention will be described below with reference to the drawings. However, the embodiments shown below exemplify earrings for embodying the technical idea of the present invention, and the earrings of the present invention specify the shapes, structures, and arrangements of the components to the following structures. Not a thing. The earrings of this device are
Various modifications are made within the scope of the claims for utility model registration. Further, in this specification, in order to facilitate understanding of the scope of claims for utility model registration, the numbers corresponding to the members shown in the embodiment are
It is added to the members shown in the "column for claim for utility model", "column for means for solving conventional problems" and "column for action". However, the members shown in the scope of claims for utility model registration are by no means limited to the members of the embodiment. The earring 1 shown in FIG. 1 is composed of a decorative body 2 and a fixing fitting 3 for attaching the decorative body 2 to the ear. The decorative body 2 is formed of clay into a spherical shape with a convex center. The decorative body 2 shown in FIGS. 1 to 3 is formed in a shape having a hemispherical upper end and a flat bottom surface.
The decorative body 2 having this shape has a feature that it can be stably placed on a horizontal table. However, this device does not specify the shape of the decorative body 2 to the shape shown in the figure. For example, although not shown, the entire shape may be a substantially spherical shape with a small flat surface on the bottom surface, or it may be formed into a triangular or quadrangular pyramid shape to have a three-dimensional shape with a convex center. The decorative body 2 is provided with a fixing hole 6 at the center of its bottom surface so that the fixing fitting 3 can be fixed securely. The fixing hole 6 is formed in the step of molding clay. The decorative body 2 formed of clay is sufficiently dried. If the drying is not sufficient, the decorative body will be cracked during the firing process, resulting in poor yield. Therefore, the dried decorative body 2 has a moisture content of
It is preferably adjusted to 0.5% or less. The dried decorative body 2 is biscuit-fired and fired. The fired substrate is colored by applying glaze on the surface. When the glaze is melted in the firing step, it flows down from the upper portion to the lower portion, and is applied in such a thickness that the upper portion is thin and the lower portion is thick. If the amount of glaze applied is too thin, the molten glaze will not flow down. Therefore, the glaze is applied to the surface of the base material sufficiently thickly. As the glaze, one that can color the substrate can be used. For example, glaze may be a glaze for a pottery containing a coloring agent such as copper, iron, chromium, cobalt, uranium, iridium, manganese, or nickel, or a gold or silver solution. It is possible to specify the type of coloring material contained in the glaze and the color of the decorative body baked in the baking environment. For example, in order to color the decorative body blue, oxidation or baking is performed by using copper or cobalt as a coloring material, or reduction baking is performed by using chromium or cobalt as a coloring material. Also,
In order to color the decorative body red, oxidation is performed by using iron as a coloring material, or reduction firing is performed by using copper as a coloring material. Furthermore, manganese can be colored by oxidation and firing to be purple, nickel can be colored by oxidation and firing to be green, and titanium can be colored by oxidation or reduction to be colored in a gradual color. Salt glaze, alkaline glaze, green glaze, celadon glaze, glazed glaze and the like can be used as the glaze containing these coloring materials. The decorative body coated with the glaze is carried into the firing furnace with the central convex portion facing upward, and the temperature at which the glaze melts, for example, 80
Baking at 0 to 1300 ° C. The melted glaze flows down by its own weight to become a gloss layer 5 of a color having a natural shade, and colors the decorative body. That is, the gloss layer 5 colors the upper part of the decorative body in a light color and in a natural state in which it gradually darkens toward the lower part. It is also possible to coat the surface of the decorative body 2 with two layers of glaze so that the upper part and the lower part are colored in different colors. In this case, after applying a glaze as a base to a thin film on the surface of the base material and drying it, a top coat glaze having a different color is thickly applied and baked on the glaze.
When this decorative body 2 is baked, the glaze for glaze melts and naturally flows down, and the upper part of the glaze is colored in a color close to the glaze for glaze and toward the lower part in a color close to the glaze for glaze. As described above, if the glaze is applied to the unglazed clay after the clay is dried, the glaze can be easily applied. However, it is also possible to directly apply the glaze without dying the dried clay. According to this method, since it can be manufactured by one-time firing, it has a feature that it can be manufactured easily and efficiently. The fired and colored decorative body 2 is fixed to the fixture 3 using an adhesive. However, although not shown, it is also possible to provide a female screw in the fixing hole 6 of the ornamental body 2 and screw in a screw (not shown) provided in the fixing fitting 3 to fix it. The fixing metal fitting 3 fixes the decorative body 2 to one end which is U-bent, and has a screw 4 which is fixed to the other end with the earlobe interposed therebetween.

[Effect of device]

The earring of the present invention uses a fired product formed of clay as a decorative body. The decorative body is made by molding clay into a central convex shape and applying glaze to the surface thereof. The glaze applied to the surface of the ornamental body formed in this shape can be melted in the firing step and allowed to flow down. The glaze melted and flowed down does not color the front surface of the decorative body in the same color, but gradually colors it in a dark color from the upper part to the lower part. Unlike the case of writing with a brush or the like, a colored decorative body in this state has a beautiful dark and light difference in color in a natural state. Therefore, the earrings of this invention have the feature that they can be mass-produced at low cost using clay, which has a high unit price, and that the glaze that melts and flows down in the fired state makes it a beautiful ornament that is not inferior to natural gemstones. . In addition, the glaze that melts forms a glossy and beautiful colored layer on the surface of the decorative body, and this colored layer is hard to be scratched without being affected by climate change and can be used beautifully for a long time There is.
