The present invention relates to a method for manufacturing celadon using Mossbauer spectroscopy according to decisions on plasticity atmosphere conditions of pottery chromacity and, more specifically, to a method for manufacturing celadon using Mossbauer spectroscopy according to decisions on plasticity atmosphere conditions of pottery chromacity which: measures quantitative ionic valency of Fe ions on a ceramic glaze layer using the Mossbauer spectroscopy having 10^-12eV of accuracy in order to decide accurate ion ratio of the Fe metals in Fe^2+ and Fe^3+ produced by reduction reaction of a ceramic glaze layer during a high temperature reduction firing process; gives accurate reduction intensity of the celadon by quantitavely suggesting the reduction intensity according to the amount of LPG gas which is reduction firing gas; quantitavely suggests a decision method of the reduction firing condition which manufactures according to celadon green of the celadon by measuring data of chromacity (L*,a*,b*) of the glaze layer according to the firing reduction condition of the pottery and suggesting quantitative reduction firing condition of the Fe ionic valency and the chromacity; quantitatively controls the Fe ionic valency through reduction firing condition adjustment by a manufacturer; and manufactures desired colored celadon. [Reference numerals] (AA) Step of primary heating white porcelain testing piece in furnace while increasing 3°C per minute from room temperature to 900°C; (BB) Step of cooling the primarily heated white porcelain testing piece from 900°C to room temperature after maintaining at 900°C for one hour; (CC) Step of mixing glaze with the cooled white porcelain testing piece and coating the white porcelain testing piece with the glaze with a density of 1-2 g/cc; (DD) Step of secondary heating the glaze coated white porcelain while increasing 3°C per minute from room temperature to 900°C in the furnace; (EE) Step of tertiary heating the secondarily heated white porcelain while increasing 1°C per minute from 900°C to 1260°C in the furnace which supplies 0-35L/min of LPG gas which is reduction gas and 7L/min of air; (FF) Step of cooling the tertiarily heated white porcelain from 1260°C to room temperature after maintaining at 1260°C for one hour |
