Abstract

(57) [Summary] [Purpose] To provide an alternative to ivory. Composition: Treats animal horns by applying heat and pressure to improve tissue, appearance and durability. This method is particularly suitable for treating sheep horns for use in marking crafts.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The invention relates to the use of animal horns or fangs for the production of crafts such as statues or ornaments, or figurines such as paperweights or seals. The present invention particularly relates to a method of treating animal horns.

[0002]

[Prior Art]

 Ivory from ivory tusks is traditionally used to make small crafts. Ivory is in great demand because of its excellent appearance and durability and its suitability for high-quality precision engraving. However, the trade in ivory was banned because it was so wasteful to kill an elephant solely for its ivory because of nature conservation. In light of the general demand for natural products, other natural products are used as alternatives to ivory. In particular, the horns of other animals that are slaughtered for meat are used.

The most common alternative is cattle horn. Cattle horns are particularly suitable because a large number of cattle are slaughtered and the horns are discarded unless used as a substitute. In addition, the relatively large corners are used, keeping in mind that the corners actually have few textures that can be carved into the final product and many of the corners cannot be used. Is desirable. Unlike ivory, the horns of cows are black. Cattle horns are not rated as ivory because they are not rarely valuable and because the appearance of cow horns is generally not as attractive as ivory.

[0004]

[Problems to be solved by the device]

 A less common alternative to ivory is sheep horn. Sheep horns are less common because most of them are unusable and only a few have a texture and quality suitable for carving.

[0005]

[Means for Solving the Problems]

 The present invention provides a method of treating animal horns that improves the texture, appearance and durability of the animal horns. This method applies heat and pressure to the animal's horns to improve its tissue and, preferably, lacquers to improve appearance and protect the exterior. This method is particularly applicable to sheep horns, allowing more of the sheep horns to be usefully used.

This method will be described more specifically below with reference to the accompanying drawings. In the accompanying drawings, one particular sequence of the method steps according to the invention using sheep's horns for the production of seals is shown as a simple example.

[0007]

【Example】

 First of all, with reference to FIG. 1, it will be immediately understood that sheep horns can only be used to a very small extent in carving traditional methods. Many parts of the horns of sheep have a very thin and brittle shell-like texture, are curved in shape, have a rough surface texture and contain many impurities. Only the part marked with "A" is suitable for engraving.

[0008] Referring now to FIG. 2, the seals shown in this figure, which are of very high quality in terms of texture and appearance, show that the horns of sheep shown in FIG. It cannot be made using the engraving method. Referring to FIG. 3, a portion of the sheep's horn marked with the symbol "A" in FIG. 1 is cut out from the sheep's horn and flattened by pressing to make the illustrated horn piece. The rest of the corner is discarded.

Referring to FIG. 4, the piece shown in FIG. 3 is cut into the same blocks of sheep's horn. These blocks have a relatively rough and rough surface and contain defects such as cracks and bubbles. Referring now to FIG. 5, in order to soften the material, each block is subjected to repeated heating steps and pressure is applied to form the softened material, which causes the blocks to have the cylindrical shape shown in the bottom of FIG. Gradually transform into. The exact number of heating and pressing steps and the temperatures and pressures applied depend on the texture and quality of the sheep horn. The minimum temperature required for softening row A is about 80 ° C and the minimum pressure required for reshaping is about 500 kg. After each step, the work piece is old with water. Generally speaking, the temperature and pressure are gradually increased in each successive step. Overall, the effect of eliminating defects such as cracks and bubbles, the effect of slightly increasing the density, and the effect of changing the color to a semi-transparent brown with an excellent appearance are obtained.

The degree of browning can be changed by changing the temperature applied. The step after heating and pressing is to cut the end of the cylinder using a lathe to form the dome-shaped end. After cutting the dome-shaped end, the step of polishing the surface of the dome-shaped cylinder is performed.

After polishing, the domed cylinder is coated with lacquer. This involves dipping the cylinder into the lacquer, then the liquid lacquer flows down the length of the cylinder to form a smooth, even finish, with the domed end at the top of the cylinder. By standing upright. The final step is to cut the flat end of a lacquered cylinder with domed ends so that all cylinders have the same length, then the braided ends are sealed. It

The final product provided by the manufacturer is a bundle of lacquered cylinders with dome-shaped ends that have the same length and a desirable brown transparent appearance. The seller engraves the required pattern, labeled "ABC" in Figure 2, on the flat end of the cylinder. The method described above is carried out in a very humid environment, for example in an environment where the relative humidity exceeds 80%, so that the corners are not brittle or cracked easily.
