Abstract: A medium substance has not been detected in the wall paintings of the Goguryeo tombs. The most important concern of the world’s cement and concrete researchers has been a method for neutralizing lime mortar. The reason is that the naturalization of lime mortar contributes not only to the improvement of strength and the prevention of oxidation, but also to significantly increasing durability. This study was conducted to examine ions in the leachate from the wall paintings of the Goguryeo tombs and to compare and analyze its pH value with one of the calcium (Ca) based finishing layer that was revealed by experiments. The results showed that both of them were neutralized by pH7. The neutralization of lime mortar varies depending on the type of glue, in terms of its functions and performance.


Key words: finish layer paint, jeongbun, dog skin glue, pH, neutralization
