The Celadon Color texture Related to the Firing Kiln Atmosphere
김만종 Man Jong , Kim
Abstract
The artistic color texture of the Korean celadon is obtained by uniform reduction of 2-3% Fe₂O₃to FeO contained in the body and glaze material with strong and continuous reducing flame produced by the fire wood. Motley brown colors were evolved during unsuccessful firing from vagrance between oxidizing and reduction flame through the formation of color compounds with Fe₂O₃, Fe₃O₄and FeO color layers rather than from excessive reduction or concentration of the iron oxides in the raw material. Strong reducing flame obtained from the gasification combustion furnace using the Korean anthracite as the fuel served for the same purpose of satisfactory reduction of Fe₂O₃to FeO producing excellent celadon color.
