Studies on Overglaze Stain

유상채색료에 관한 연구
Chong Keun Lee, Yong Wan Park

이종근, 박용완
High-fire stain is influenced by the conditions of glaze, firing atmosphere, etc. On the contrary, low fire stain is not influenced by those conditions but obtainable in arbitrary colors and it is indispensable for pottery decoration. It is difficult for us to study into the color in the sphere of result publication method and expression of color. Looking over the literature on this subject, I have been confronted with much difficulties, accordingly, I made a basic and systematic experiment as to six low-firing stains (blue, green, blue-green, brown black and yellow) and made it proper to be applied in these studies. On pigment, I confirmed the influence of the assistant coloring matter by mixing up the coloring matter and the assistant coloring matter in various proportions. On flux, I measured the melting point by making PbO-SiO2 system and PbO-B2O3-SiO2 system and decided the range of usage. Also I checked the coloring by making the pigment on laze with pigment and flux manufactured, and concluded the pigment and flux adaptation to it.
