JPH091998A - Method for treating animal horn by heating and pressurization - Google Patents

Abstract

PROBLEM TO BE SOLVED: To improve the organization, appearance, and durability of an animal horn by applying a specific temperature and pressure to the horn and rapidly cooling it with water. SOLUTION: The large part of a sleep horn has an extremely thin, fragile, and shell-shaped organization and is curved and the surface organization contains rough and much impurity. When using this sort of sheep horn to manufacture a seal, first the piece of the sheep horn is cut to form blocks with the same size. Then, heating process is repeatedly applied to each block for softening the material. Then, the softened material is pressurized to gradually deform the block into cylindrical shape. In the series of processes, a heat which is equal to or more than 80 deg.C and a force which is equal to or more than 500kg are applied to the horn and the horn is rapidly cooled after each process. In this case, after the final heating and pressurization, the horn should be coated with lacquer to improve appearance and to protect external surface.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to the use of animal horns or fangs for the manufacture of crafts such as statues or decorations or figurines such as paperweights or seals. The invention relates in particular to a method for treating animal horns.

[0002]

BACKGROUND OF THE INVENTION Ivory from elephant tusks has traditionally been used to make small crafts. Ivory is in great demand due to 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 just for ivory because of conservation.
In light of the general demand for natural products, other natural products have been used as substitutes for ivory. In particular, the horns of other animals slaughtered for meat have been used.

[0003] The most common alternative is cow horns. Cattle horns are particularly suitable because large numbers of cattle are slaughtered and horns are discarded if not used as a replacement.
Furthermore, the use of relatively large corners is important, noting that the corners are, in fact, only a few tissues suitable for engraving to produce the final product, and that many of the corners cannot be used. Is desirable. Unlike ivory, the horns of cows are black. Cattle horns are not as valued as ivory because cow horns are of no value and the appearance of cow horns is generally not as attractive as ivory.

[0004]

A less common alternative to ivory is sheep horn. Sheep horns are less common because most of them are unusable and there are only a few that have the tissue and quality suitable for engraving.

[0005]

According to the present invention, in a series of steps, heat of 80 ° C. or more and 500 k
g of force, and after each step, quench the animal's horn with water,
Preferably, after the last heating and pressing, the horn of the animal is lacquered to improve its appearance and protect the exterior, improve the texture, appearance and endurance of the animal's horn, treat the animal's horn Provide a way.

[0006] The method will be described more specifically below with reference to the accompanying drawings. The accompanying drawings show by way of example only one specific sequence of the method steps according to the invention using sheep horns for the production of a seal.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring first to FIG. 1, it will be readily appreciated that sheep horns can be used very little usefully for carving in a traditional manner. Many parts of the sheep's horn have a very thin and brittle shell-like texture, are curved in shape, are rough in texture, and contain many impurities. Only the part with the symbol "A" is suitable for engraving.

Referring now to FIG. 2, the seals shown in this figure, which are of very high quality in terms of texture and appearance, are taken from the sheep's horn shown in FIG. 1 to the conventional one, except for the very large sheep's horn. It cannot be made using the engraving method. Referring to FIG. 3, a portion of the sheep horn marked with "A" in FIG. 1 is cut out from the sheep horn and flattened by a pressing operation to form the illustrated horn piece. The rest of the corner is discarded.

Referring to FIG. 4, the pieces shown in FIG. 3 are cut into the same block of sheep horns. These blocks have a relatively rough and rough surface and contain defects such as cracks and air bubbles. Referring now to FIG. 5, a heating step is repeatedly applied to each block to soften the material and pressurized to form the softened material, thereby gradually bringing the block into the cylindrical shape shown at the bottom of FIG. To be deformed. The exact number of heating and pressing steps and the temperature and pressure applied will depend on the texture and quality of the sheep horns. The minimum temperature required for softening row A is about 80 ° C. and the minimum force required to perform reshaping is about 500 kg. After each step, the work piece is obsoleted with water. Generally speaking, the temperature and pressure are gradually increased in each of the successive steps. As a whole, 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 translucent brown having an excellent appearance can be obtained.

The degree of brown color 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 a dome-shaped end. After cutting the dome-shaped end, a step of polishing the surface of the dome-shaped cylindrical body is performed.

After polishing, the dome-shaped cylinder is coated with lacquer. This involves immersing the cylinder in a lacquer and then lining the cylinder with the dome-shaped end on top so that the liquid lacquer flows down the cylinder lengthwise to form a smooth and even finish. This is done by standing upright. The last step is to cut the flat end of the lacquered cylinder with a dome-shaped end so that all cylinders have the same length, then the slick ends are sealed .

The end product provided by the manufacturer is a bundle of lacquered cylinders with domed ends of the same length and a preferred brown, transparent appearance. Seller 2
The required pattern, labeled "ABC", is engraved on the flat end of the cylinder. The method described above is carried out in an extremely humid environment, for example in an environment where the relative humidity exceeds 80%, so that the corners are not brittle or cracked easily.
