Abstract

The present invention relates to a method for manufacturing a Baekhwolrye porcelain, which is characterized in that a new texture of a porcelain is expressed by virtue of the fact that a hundred grains oil glaze is applied to the surface of the porcelain, and the durability of the porcelain is improved.
In order to accomplish this, the present invention provides a method of manufacturing a ceramic article, A pre-baking step of baking the formed pottery at 850 to 900 캜; Wherein the surface of the unglazed pottery has a composition of 30 to 50 wt% of glutinous rice straw, 10 to 20 wt% of oak, 20 to 30 wt% of feldspar, 5 to 10 wt% of silica, and 5 to 10 wt% And a glaze is applied; And a chaebol baking step of baking the refined pottery at 1250 to 1300 ° C.

Description

{MANUFACTURE METHOD FOR CERAMIC}

The present invention relates to a method for manufacturing ceramics, and more particularly, to a method for manufacturing ceramics, in which a glaze material coated on the surface of ceramics is made to contain carbonized material such as rice straw, &Lt; / RTI >

Generally, ceramics can be classified into various kinds according to kinds of clay, molding process, sintering process and sintering temperature, kind of glaze or decoration technique, name of production area, purpose of use. There is a classification by clay composition and firing result such as celadon, white porcelain, Onggi, and ash pottery (it is also related with the development history of oneself), classification by glaze and decoration method, Jinja, and faiji.

It can be classified as soft magnetic or hard magnetic according to the firing temperature. It can be called as baking, rocking, open-air firing and fire-firing by baking method. Depending on the application, And industrial ceramics such as insulators, electronic parts, and chemical containers.

As a conventional technique for manufacturing such ceramics, a technique relating to a ceramics manufacturing method having a new visual sense is proposed in Patent Registration No. 508854.

However, in the ceramics manufactured by the above-described conventional techniques, the glaze layer on the surface is easily broken by the insect pests, so that the durability of the ceramics is reduced and the color is changed to deteriorate the appearance of the ceramics.

The present invention has been proposed in order to overcome the problems of the prior art described above, and it is an object of the present invention to provide a ceramic surface coating layer in which a carbide component can be added to a glaze used to form a ceramic surface coating layer, So that it can be further increased.

In order to achieve the above object, the present invention provides a method for manufacturing ceramics, comprising the steps of: A pre-baking step of baking the formed pottery at 850 to 900 캜; Wherein the surface of the unglazed pottery has a composition of 30 to 50 wt% of glutinous rice straw, 10 to 20 wt% of oak, 20 to 30 wt% of feldspar, 5 to 10 wt% of silica, and 5 to 10 wt% And a glaze is applied; And a chaebol baking step of baking the refined pottery at 1250 to 1300 ° C.

The present invention provides a new white texture of ceramics improved in gloss as a result of porcelain refining using a white phosphorus oil glaze containing glutinous rice straw as a carbonaceous material and oakwood as well as enhancing the durability of ceramics, Can be further increased.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a flowchart of a process for manufacturing ceramics according to an embodiment of the present invention. FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, a process of manufacturing a ceramic according to an embodiment of the present invention will be described with reference to FIG. 1, which includes a forming step of forming a clay base into a ceramic form, a preliminary step of firing the formed ceramic at 850 to 900 ° C, The process of applying the glaze on the surface of the ceramics, and the stage of the chaebol, which burns the ceramics which have been made with water, at 1250 ~ 1300 ℃, are sequentially performed.

Particularly, in the above-mentioned refining step, in the present embodiment, the composition comprising 30 to 50 wt% of glutinous rice straw, 10 to 20 wt% of oak, 20 to 30 wt% of feldspar, 5 to 10 wt% of silica, and 5 to 10 wt% A hundred gallon oil glaze is applied.

That is, in the glaze of the present embodiment, the surface color of the ceramics can be displayed more whitened by adding the glutinous rice straw material, and the oak material can be melted at a lower temperature than the pine material, The flowability of the glaze together can be improved.

Further, as an application example, addition of 1 to 5 wt% of sodium silicate and 1 to 3 wt% of glass wool to the white pearl oil composition increases the viscosity of the glaze and improves the gloss effect of the surface of the ceramics due to the glass ingredient The strength of the glaze layer can be enhanced.

Therefore, the white glaze oil glaze of the present invention can form a glaze layer with a more stable and uniform thickness, thereby increasing the durability and storage period of the ceramics.

Meanwhile, as another embodiment of the present invention, an infrared ray irradiation step may be further performed to radiate the infrared rays for 5 to 10 minutes so that the applied glaze can be formed on the surface of the ceramics uniformly before the chrysanthemum roughening step.

When such an infrared radiation step is carried out, 1 to 5% by weight of sodium silicate and 1 to 3% by weight of a zirconium component which can be activated by infrared rays in the infrared radiation step are added It is preferable to further add it.

As an example, a composition of glutinous rice paddy stain 47 wt%, oak wood 20 wt%, feldspar 20 wt%, silica 5 wt%, dolomite 5 wt%, sodium silicate 2 wt%, zirconium 1 wt%

When the infrared ray irradiation process is performed in the state where the white oil glaze forming the above composition is used, preheating of the glaze layer by infrared rays is performed, so that the thickness of the glaze layer can be uniformly maintained as a whole.

In addition, since zirconium is activated by infrared rays, the firing temperature during the chaebol roasting process can be further reduced to 1250 to 1270 ° C.

Although specific embodiments of the present invention have been described and illustrated above, it is to be understood that the process of making ceramics of the present invention can be carried out by a person skilled in the art in various ways.

It should be understood, however, that such modified embodiments are not to be understood individually from the spirit and scope of the invention, and such modified embodiments are intended to be included within the scope of the appended claims.
