초 록
태안 마도 출토 도자기를 대상으로 도자기 탈염에 일반적으로 사용되는 물 세척법에 추가조건(탈염수 양, 교반 및 온도)을 적용하여 탈염효율을 비교 연구하였다. 탈염수 양에 따른 효율실험결과 질량비 20배가 질량비 10배보다 효율은 높았지만, 그 정도가 2배에 미치지 못하여 경제적 측면에서 질량비 10배가 보다 효율적이었다. 또한 탈염처리 중 교반 및 가온에 따라 20~30%의 효율증대는 확인되었지만, 추가기법적용을 위한 에너지사용과 물리화학적 충격에 의한 유물손상의 위해성을 종합적으로 고려한다면 교반 및 가온에 따른 효율증대는 크지 않은 것으로 판단된다 .

ABSTRACT
This paper focused on desalination method for the underwater archaeological ceramics. The desalination method applied in this study takes additional conditions such as the amount of desalting water, temperature, and agitation conditions and compares the effects of desalt process. The result of efficiency rate appears that the twenty-times of the object weight of desalting water is more effective than that of ten-times one, but shows less economic compared to the cost. In addition, the research shows that the efficiency rate has been improved around 20 to 30 %, yet such improvement is not taken into account as an effective result considering the risk of damage from the physical and chemical impact and the consumption of energy in applying additional method.
Key Words: Underwate archaeological ceramic, Soluble salt, Desalinating water, Agitation, Temperature, Absorption
