Description

The present invention relates to a method for glazing ceramics, and more particularly, to a novel ceramics that enables color development with glaze simultaneously with color development with rice straw.

Conventional glazes can be broadly classified into three items, ie, wet, dry, and volatilization methods, as a traditional glazing method, apart from natural acupuncture (see Non-Patent Document 1). In other words, it has been applied to the surface of the object with any design by putting the object as a work directly in the liquid glaze, applying a glaze on the surface of the object, or painting (see Patent Document) . Therefore, the glaze application method, such as wrapping around the surface of a work like a spear , has not been used until now because it is liquid .

In addition, conventional natural firewood is an ash that has fallen naturally during firing in a kiln, so that it was not possible to intentionally design for color development. In the case of Bizen ware, red colored line patterns (patterns called “firewood”) were only expressed by wrapping or placing rice straw softened with wooden caskets around the surface of the vessel like a cocoon. Met.

 An object of the present invention is to provide a glaze capable of producing ceramics with a high degree of design in view of the limitations of conventional liquid glazes and natural glazes as described above.

In order to solve the above problems, the present invention immerses rice straw in a liquid glaze. In addition, by using this glaze, green body (also referred to as "white") or unglazed, or wrapped around the sash shape in a free design for the ceramic after the grilled by glazed, taking advantage of the characteristics of the該稲straw order to firing color in the state, was the method of manufacturing the釉襷products that can be fired colored sash-like line fingerprint pattern in the new design is not until now the color produced by the color and the glaze on the ceramics of the surface with rice straw.

The glaze made from rice straw according to the present invention can be used as a flexible glaze by wrapping it around a base, unglazed or baked ceramic. Accordingly, it has become possible to produce a baked color which cannot be formed in a liquid form or in a powder form, which has been impossible with the conventional glazing method according to the above three items. As a result, in the manufacturing method of the rice bran product using this, while making use of the characteristics of the fibers such as bending, crushing, and knitting, the shape of the glaze by rice straw can be applied as it is in the form of a line pattern glazing and coloring, There is an advantage that works and products can be made by design with various decorations and a completely new concept.

It is the figure which showed an example of the manufacturing method of the glaze by the rice straw which concerns on this invention. It is the figure which showed an example of the usage method of the glaze by the rice straw which concerns on this invention. It is the perspective view which showed Bizen pottery as a candy product which concerns on this invention. It is the perspective view which showed the Bizen pottery flower basket as a cocoon product which concerns on this invention. It is the perspective view which showed the Bizen baked sake sachet as a cocoon product which concerns on this invention.

The present invention will be described below. FIG. 1 is an explanatory view showing an example of a method for producing glaze using rice straw according to the present invention. In the conventional glazing method, a glaze prepared by dissolving a raw material such as pine ash in water and stirring it was applied to the work by the above-mentioned three glazing methods. and stirred filled with water 3, soaked rice straw 4 in glaze 5 was liquid, the glaze by rice straw impregnated with glaze as a medium rice straw 4. The degree of immersing the rice straw 4 in the glaze 5 may be adjusted by lightly or firmly immersing the rice straw 4 depending on the desired degree of firing color. The rice straw 4 soaked in glaze may be used after lightly draining, but may be used semi-dry or completely dried.

In the case of using a powdered glaze that does not dissolve in water as the raw material of the glaze, the glaze by rice straw in which rice straw 4 is entangled and adhered as a medium. Here, adhesion means that the rice straw 4 is preliminarily attached with an adhesive such as light moisture or glue and then dusted with a powder glaze. In the present invention, such powder glaze is also referred to as “impregnation”.

In the manufacturing method of釉襷product according to the present invention, as shown in glaze 2 according to FIG rice straw, for example, on the surface of the liquor bottle 6 (not shown) glaze 4 to calcining wound in any design (firing). As an object such as Tokutori 6, it can be applied to not only a molded base, but also a ceramic that has been baked once or twice, or that has been baked.

The glaze 4 made of rice bran in this example is a single fiber, but various shapes such as those obtained by twisting a plurality of fibers into a rope shape or knitting can be adopted. In Inagi, it can be produced by striking a wide area and wide area by striking it with a wooden mallet, and using one or more rice straws with multiple types of glaze. It is also possible to change the glaze to be impregnated partially to bring about a difference in coloring effect. In this way, the color of the glaze impregnated on the red color of the rice bran attached to the container and burnt down by firing is also expressed as a koji pattern 7 by leaving traces on the surface of the container. In a plate-like container such as a dish, the glaze 4 of rice straw that has been cut into small pieces can be sprinkled and attached.

3 to 5 show examples of completed ceramics manufactured by the method described above. It can be seen that the glaze of glaze made from rice straw using rice straw on the surfaces of Bizen Yakitokuri, Kakehanaji, and Gyuomi is clearly baked in green.

The present invention, as a product and work taking advantage of the characteristics of the釉襷of glaze by rice straw, free decoration enhanced the aesthetic value to the firing color in decorated with the design of the medium of the rice straw, ceramics, metal, ceramics It is used in industries that produce glass and the like.

Claims (1)

Rice straw is impregnated with glaze, and the rice straw is wrapped around the surface of the ceramic after being burned or unglazed or fired in a bowl shape and fired in a state where the characteristics of the rice straw are utilized. A method of glazing with rice straw in ceramics, characterized in that the color development by straw and the color development by glaze were made to appear on the surface of the ceramic as an unbroken line pattern .
