코발트 발색에 대한 연구

Abstract

In Korean university, we teach three different categories of ceramics, namely, traditional ceramics, industrial ceramics, and formative ceramics. Some universities emphasize more on tradition, while others emphasize formative ceramics. In the university where female ratio is greater than male, they tend to teach industrial ceramics along with the other class, due to the nature of the subject, which requires delicacy and patience. After molding and forming, the object goes through bisque firing, and, to display different texture, there is process of coloring. Usually, iron or cobalt is used, but they sometimes are troublesome as they smear onto hands or runs down on the object. It can be said that this may be the one of reason why the white or transparent kind of glaze gets polluted due to powdery material of color come up. After the second firing, wesometimes find the object still retains the running of the glaze. So we did an experiment to maintain the transparency of glaze and to prevent running phenomenon. We mixed CMC in powder state with water, and we mixed the solution with glycerin and glaze to find the point where it does not smear onto hands, yet it is good to brush with. There is preference in the choice of color for everyone. However, I am sure one can find his unique color with careful selection of color, experiment, and research.
