Hereinafter, the present invention will be described in more detail with reference to Examples. It is to be understood by those skilled in the art that these examples are for illustrative purposes only and that the scope of the present invention is not construed as being limited by these examples.
Example 1. Preparation of Mugwort ash and analysis of components
The mugwort (the source of the mugwort as an experimental subject was the mugwort of Ganghwa-do) was immersed in water, stirred well and left at room temperature for 24 hours. After that, only the water was removed so that the wormwood ashes did not come down, and then water was added again to stir well. This operation was repeated several times until the water was not smooth, and then the mugwort was dried at 80 to 100 ° C to obtain a wormy material to be used as a glaze material. The components of the mugwort were analyzed (see Table 1 and FIG. 1).
As shown in Table 1, 10.97 wt% of phosphorus oxide (P 2 O 5 ), which softens the feel of the glaze for pottery, is contained more abundantly than other materials, so that a clear and warm feeling can be exhibited. It also contains iron oxide (Fe 2 O 3 ) which affects the color of the glaze. It can also be seen that the wormwood contains a large amount of a potassium oxide (K 2 O) component (23.34 wt%) and a magnesia (MgO) component (9.74 wt%).
Example 2. Composition other than Mugwort
Feldspar is an aluminum silicate mineral containing potassium, sodium, calcium, and barium. It is a major component of the granite and is mainly composed of a series of three single components, potassium feldspar, sodium feldspar, and calcium feldspar. Potassium feldspar, sodium feldspar, and calcium feldspar and sodium feldspar form a continuous solid solution, each of which is generically referred to as alkali feldspar and plagioclase.
In the present invention, feldspar serves as a melting agent and functions to lower the melting point of the glaze. Therefore, if the content of feldspar is too small, there is a problem that the glaze is not sufficiently melted to form a rough surface or a glaze curling phenomenon. On the other hand, if it is too much, there is a problem in flowability and color development of glaze. There is no particular limitation on the feldspar, but it is preferable to use the fungicide of Chungnam Province.
Limestone (limestone) is a type of hydrous rock composed mainly of calcium carbonate (CaCO 3 ), which is produced by chemical precipitation in seawater or by fossil creatures with calcareous shells. Generally, limestone having a CaCO 3 content of 45% or more is mined, and impurities include silicon dioxide, alumina, and magnesia. In industry, it can be used as a neutralizing agent, but because it generates carbon dioxide gas, it needs to stir for a long time to aeration, and there are various uses such as raw materials for coal, cement, glass, carbide, iron and chemical industry.
The limestone serves as a solvent to lower the melting point, and also affects the gloss and flexibility of the surface of the glaze. If the content of the limestone is too small, the glaze does not dissolve well and there is a problem that the surface of the ceramics after roasting is likely to become rough. The limestone is not particularly limited, but it is preferable to use Chungju, Chungju, Korea.
Silica stone is anhydrous silicic acid (SiO2), and its chemical composition is high in purity and white is called white gypsum. It is calculated from pegmatite, quartz vein, quartzite, chert, The amount of silicate is 95 to 97% or more. Particularly, pegmatite is mined along with feldspar, so it is called long-stones. Baekgukseok is mainly used as a raw material for glass, ceramics, silicon, and ferrosilicon.
On the other hand, Yeokgukseok (soft silica stone) is weathered quartzite rock to form a soil form. It is mixed with clay. It is used as a mixed material of refractory mortar and cement, and silicate content is about 90%. Furnace quartz is a type of chert, which contains iron, so it has a red corrugated gravel and becomes the main ingredient of refractory bricks.
The inner stone is a small piece of silica and has a diameter of 5 to 15 cm and is used for the interior of a ball mill for crushing ceramics. In the present invention, it is preferable to use white celadon as a main material of the glaze, and it functions to increase glass whiteness and whiteness.
When the content of the silica is too small, the glaze is not sufficiently melted and the surface is roughened. On the contrary, when the content of the silica is too large, the glaze is not melted well or the glaze is curled and yellowish spots are formed too much. There is no particular limitation on the above-mentioned silica, but it is preferable to use Gyeongsan Mountain, Chungnam Province.
Kaolin (kaolin) is a basic formula is represented by Al 2 Si 2 O 5 (OH ) 4, also referred to as Ai (磁土) or whiteness Sat (白陶土). As a high-purity clay, whiteness is used as the main ingredient of ceramics. Minerologically, it has been thought to consist of kaolinite, but it has the same chemical formula as nacrite and decite, and kaolin minerals have three of these.
In the present invention, the kaolin suspends the glaze slip and further adheres the glaze slip to the substrate. When the content of the kaolin is less than 10% by weight, the glaze layer may peel off from the surface of the ceramic. On the other hand, %, The yellow spots are formed too much, which is undesirable. There is no particular limitation on the kaolin, but it is preferable to use kaolin.
Example 3 Preparation of Porcelain Test Specimens Made of Wisteria Glaze
The glaze compositions prepared by mixing the respective components according to the composition ratios shown in Table 2 were mixed in water of about 1.5 times each, and each of these glazes was sieved in a white cup, and then put into a gas kiln and heated at a temperature of 1,250 ° C. To prepare a white cup.
FIG. 2 is a photograph of a porcelain obtained by using the glaze composition of the present invention. FIG. 2 is a photograph of a porcelain with a composition ratio of 1 and a thickness of 0.3 mm or less. FIG. It is a pottery that has been cultivated. As shown in Fig. 2, it has a soft blue color and a glossy texture.
Generally, ceramics are expressed as glitters and matrices by various factors, and it is understood that the ratio of the contents of silicate and kaolin is the biggest factor influencing the gloss or matt phase. That is, irrespective of the order of the silicate and kaolin, the content is expressed as a luminous flux within the range of 1: 1 to 1: 3.
The glaze composition according to the present invention has been found to produce a glazed whitish texture of a glazed white background, which is sensitive to blue light when used on a white porcelain such as a water cup, coffee cup, saucer, bowl and the like.
Having described specific portions of the present invention in detail, those skilled in the art will appreciate that these specific embodiments are merely preferred embodiments and that the scope of the present invention is not limited thereby. something to do. Accordingly, the actual scope of the present invention will be defined by the appended claims and their equivalents.
