Description

{POTTERY OCARINA HAVING A ECO-FRIENDLY COLOR COATING WITH ENVIRONMENTAL COLOR COATING}

The present invention relates to a ceramic ocarina having an environmentally-friendly colored coating and a method for producing the same. Specifically, the surface of the low-temperature-baked ceramic ocarina is colored with an environmentally friendly natural dye at least once, , An environmentally-friendly colored coating capable of effectively preventing the contamination and damage on the surface of the ocarina of pottery by improving the strength and elasticity of the pottery ocarina body to reduce the damage property without damaging the characteristics (absorbency and tone) of the pottery ocarina The present invention relates to a ceramic ocarina and a production method thereof.

Unlike other musical instruments in the shape of a tube, Ocarina is a closed tube instrument that has only a blower, an edge, and a cloud. It has been made from earth since the late 19th century when it was first designed and manufactured by cutting the wood, but recently it is also made of plastic.

Ocarina is usually made of clay and is made of ceramics that have been baked at a temperature of 800 to 900 ° C lower than that of ordinary clay so that the structure of the soil is alive for a soft tone. Ocarina has a disadvantage that it is expensive, heavy, and easy to break due to its complicated manufacturing process and low productivity, which makes mass production impossible. In order to compensate for these drawbacks, many attempts have been made to produce ocarina using synthetic resin (plastic) which can be mass-produced at a constant quality and lower the manufacturing cost. Plastics have the advantages of low manufacturing cost, low weight, and low risk of breakage. However, due to disadvantages such as poor tone quality and poor product quality compared to pottery, a lot of efforts are being made to improve it.

Ocarina burnt with soil is fired at a temperature of 1200 to 1300 DEG C or higher to solve problems such as surface contamination and surface damage in the self-ocarina, but the disadvantage is that the soil loses its properties due to high temperature firing and loses tone color and water absorption characteristics .

Likewise, one of the main disadvantages of synthetic ocarina is moisture absorption problem. The porcelain ocarina, which is made of earth, still has the characteristics of the soil, so a small amount of saliva that enters the air through the tuyere during the performance is absorbed by the pottery. The absorbed saliva is dried again after storage. However, because synthetic resin ocarina or magnetic ocarina can not absorb moisture, plasticizer or self is blocked by saliva, and sometimes the saliva is removed during performance, and even if it is not blocked, saliva flows into the body of ocarina, There is a problem in hygiene such as that mold is formed inside the body of ocarina due to not being cleaned well when young students use it.

In this situation, much research has been conducted on a method for solving problems such as surface contamination and damage, while maintaining the characteristics of a ceramic ocarina having excellent water absorption and tone.

It is hygienic to prevent contamination, scratches or damage on the surface by protecting the appearance and surface without damaging the characteristics (absorbency and tone) of the ceramic ocarina which is fired at a low temperature of 800 to 1000 ° C Environment-friendly means or method.

The present inventors have found that when the surface of a low-temperature baked ceramic ocarina is colored with an environmentally friendly natural dye at least once and then is finished to a proper thickness with a natural varnish, the oakinas can be obtained without damaging the characteristics (absorbency and tone) The strength and elasticity of the body are improved to reduce the fracture property, and it has been confirmed that the contamination and damage on the surface of the ocarina of pottery can be effectively prevented.

Further, it has been confirmed that an excellent aesthetic ornamental property can be imparted to the surface of the ocarina of pottery by coloring and finishing the surface of the pottery ocarina with natural dyes and natural varnish, thereby completing the present invention.

The ceramic ocarina according to the present invention can be provided with an aesthetic ornamental property that is excellent in appearance and is prevented from being damaged, surface contamination and damage in an environmentally friendly manner.

It is a first object of the present invention to provide a method for preparing a coloring layer and a natural varnish which are derived from natural dyes extracted from herbal medicines on the surface of a ceramic ocarina which is fired at a low temperature of 600 to 1000 ° C, And a finish layer derived from the surface layer.

A second object of the present invention is to provide a process for the production of surface-treated ceramic ocarina comprising the steps of:

(A) a step of baking the ocarina oven formed with the soil at a temperature of 600 to 1000 캜, preferably 600 to 800 캜,

(B) a coloring step of coloring the surface of the potted ocarina with the natural dye extracted from the medicinal herb, curing for 12 hours, and

(C) a finishing step of coating and drying the colored potted ocarina with a natural varnish.

Since natural dyes are derived from natural materials which can be mostly used as herbal medicines, they are natural-friendly, harmless to the skin, can be mostly edible, contain coloring matter of various components compared to chemical dyes, and have a deep and natural expression of color. By combining two or more kinds of herbal medicines, it is possible to obtain natural dyes exhibiting antibacterial, antioxidative, deodorizing, anti-allergic, anticancer properties and the like, thereby being capable of various functionalities and comfortable processing. And the application of this method to the field of

Ocarina is a musical instrument that comes into direct contact with the lips and hands of a performer, but there is a possibility that odor may occur due to the water (a mixture of water and saliva) generated in the musical instrument at the time of performance. Natural dyes are essential for coloring ocarina.

Extraction and use of natural dyes or sublimation dyes from natural materials such as medicinal herbs have been extensively studied and are incorporated in the present invention by reference in the present invention.

Examples of herbal medicines which can be used in the present invention include, but are not limited to, ginseng (firewood), gardenia, prunus mellifera, rhubarb, rhubarb, sage, safflower, madder, persimmon, wormwood, Vine, dandelion, loquat, amber, mugwort, motherwort, and the like. In the present invention, all herbal medicines known in the market or listed in Oriental medicine books such as Dongbu-Gogang can be used. In addition, it is not a traditional medicinal herb but it is natural dyes obtained from foreign natural materials known to exhibit antibacterial, antioxidant, deodorizing, anti-allergic and anticancer properties. Saffran, Ulugi, Marigold, have.

Examples of the natural dyes usable in the present invention include red dyes (safflower, jojoba, madder), yellow dyes (yellowish white, gardenia, wool, chrysanthemum, spruce, hornblende, marigold, (Greenish, amber, papaya, mugwort, mugwort, etc.), and other dyestuffs (such as red flour, For example.

The above-mentioned natural dyes can be obtained by, for example, putting the herbal medicines in a water bath at a temperature of 50 to 100 ° C. for 1 to 40 hours, more specifically, 3 to 20 times by weight, specifically 2 to 10 times by weight, To 20 hours, preferably 4 to 15 hours, to prepare an extract, which can be furthermore solubilized to prepare a stock solution or a mother liquor if necessary.

On the other hand, most plant dyes bind to fibers by a special chemical treatment. This process is called mordanting. The substance used here is called mordanting agent. The amount of mordant is determined by the fiber weight and can be readily determined by a skilled artisan. However, if the amount of the mordant is small, the effect of mordanting is reduced. However, note that the mordant effect is not increased by adding more mordant than the fiber weight.

In the present invention, a mordant is not particularly required because natural dyes penetrate the soil component of the pottery, but it may be preferable to use a mordant in combination for color control and color stability.

Mordants that can be used in the present invention include, but are not limited to, algae, lye, lime, iron (ferrous acetate), vinegar, vinegar (acetic acid), salt (sun salt), glue Soybean juice (or milk), tannin materials (vine or tannin of plants, fruit juices of apple or omija), and the like.

The natural varnishes usable in the present invention can be any aqueous or oily varnish and are not particularly limited and include, for example, dry oils such as flaxseed oil, flowering wood oil, walnut oil, cellulk, , Violin, and rosin. The finish layer derived from the natural varnish may have a thickness of 0.1 to 1 mm, but is not limited thereto.

As described above, the second object of the present invention is a method for producing a surface-treated ceramic ocarina comprising steps (A), (B) and (C).

(A) a step of baking the ocarina oven formed with the soil at a temperature of 600 to 1000 캜, preferably 600 to 800 캜,

(B) a coloring step of coloring the surface of the potted ocarina with the natural dye extracted from the medicinal herb, curing for 12 hours, and

(C) a finishing step of coating and drying the colored potted ocarina with a natural varnish.

In the step (A), the baking temperature of the ocarina baked with the soil is 600 to 1000 ° C, preferably 600 to 800 ° C, which is lower than the baking temperature of general ceramics of 800 to 1000 ° C, It can be significantly lower than 1250 to 1400 ° C. The temperature may be relatively low compared to that of a typical ocarina (baking oven) temperature of 700 to 900 ° C.

The above-described coloring in the step (B) can be performed in two steps as follows:

(B-1) a primary coloring step of primary coloring with the above-mentioned dye and curing for 12 hours;

(B-2) a secondary coloring step of secondary coloring and drying with the same or different dyes as the above-mentioned dyes.

According to one preferred embodiment of the present invention, the coloring and drying can be carried out once or twice in the above-described secondary coloring step (B-2). In the above-mentioned finishing step (C), coating with natural varnish and drying may be carried out once or twice or more.

According to one preferred embodiment of the present invention, the above-described coloring using natural dyes and coating with natural varnish may be applied over the entire surface or a part of the ocarina and may be colored or coated according to any figure or pattern have.

One advantage of the present invention is that the natural dye acts to increase the adhesion or adhesion between the surface of the ocarina and the natural varnish. This is because natural dyes extracted from natural materials contain not only dye components but also fibrous components, and they penetrate to the surface of ocarina so as to improve the adhesion between the natural varnish and the surface.

Another advantage of the present invention is that the ocarina can be fired at a low pre-baking temperature to give an excellent tone, while the present invention can be painted with a natural dye and coated with a natural varnish to prevent surface contamination and damage, It is possible to reduce the manufacturing cost of the ocarina. In addition, since the present invention can be applied not only to a ceramic ocarina having a low baking temperature but also to a baking ocarina having a high baking temperature, the ocarina of the present invention can include ocarina made of pottery and earthenware.

Another advantage of the present invention is that not only the surface of the ocarina but also the pore and / or the wall of the pore can be painted with natural dyes and coated with natural varnish, which can help playing, washing and storing the ocarina. In addition, by coloring the ground with various colors, it can be helpful to educate ocarina.
