Method of manufacturing a Koryo celadon
The present invention relates to a Koryo celadon manufacturing technique including raw material soil mixing, moisturizing (purification), kneading, molding, drying, inlay, drying, biscuit firing, glazing, re-roasting, reduction firing, and finishing. According to the present invention, a first porcelain raw material is prepared by the quantitative-ratio mixing of 303 wt% of white clay, 202 wt% of potters clay, 202 wt% of Cheil clay, 202 wt% of porcelain clay, and 101 wt% of Muan clay and a glaze raw material is prepared by the mixing of 303 wt% of feldspar, 303 wt% of silica, 202 wt% of limestone, 101 wt% of pine ash, 80.5 wt% of kaolin, and 20.1 wt% of oxide iron. The first raw material is mixed at a quantitative ratio, is molded into a celadon model, is carved, and then an inlay process is executed. Then, drying is performed, biscuit firing is performed within a range of 90050 degrees Celsius and at a range of five days, gradual cooling is performed for two days, the glaze is applied, and re-roasting is performed within a temperature range of 1,000 to 1,250 degrees Celsius for three days on made fire, 41 days on soot fire, 51 days on white fire, and 51 days on red fire. In the end, re-roasting is performed for one day on melting fire within a range of 1,30010 degrees Celsius. After the re-roasting process is completed, an inlet portion of a kiln is blocked and a reduction firing process is performed in an oxygen-less airtight atmosphere for the celadon to be finished.
본원은 고려청자를 얻는 기술로 원료 흙 배합 -> 수비(정제) -> 반죽 -> 성형 -> 건조 -> 상감 -> 건조 -> 초벌구이 -> 유약작업 -> 재벌구이 -> 환원번조 -> 청자 완제품을 얻는 기술이다. 본원은 자기 원료로 백토 30±3 wt%, 백점토 20±2 wt%, 제일점토 20±2 wt%, 고령토 20±2 wt%, 무안점토 10±1 wt%를 정량비율로 홉합시켜 제1원료로 준비되고, 유약원료로 장석 30±3 wt%, 규석 30±3 wt%, 석회석 20±2 wt%, 소나무재 10±1 wt%, 카오린 8±0.5 wt%, 산화철 2±0.1 wt%가 홉합되어 유약원료를 준비되며, 상기 제1원료가 정량비율로 배합된 후 청자모형으로 성형된 후 조각하여 상감공정을 수행하고 건조한 후 900±50℃ 범위에서 5일 범위로 초벌 구이를 실시하고 2일 동안 서냉시킨 후 상기의 유약이 도포된 후 재벌구이가 실시되되, 피운 불에서 3일, 그을름 불에서 4±1일, 흰 불에서 5±1일, 붉은 불에서 5±1일간 1000~1250℃ 온도 범위에서 실시되고 최종적으로 1300±10 ℃ 범위의 녹임 불에서 1일간 재벌 구이가 실시되며, 재벌구이공정이 완료된 후 소성로의 입구부를 막아서 산소가 공급되지 않는 밀봉분위기에서 환원(還元)번조(燔造) 공정이 적용되어 청자를 얻는 기술이다.
