In order to clarify the lime-based building method used in the Joseon Dynasty, lime materials, production techniques, and mixing methods recorded in ancient literature were examined. In ancient Joseon Dynasty literature, the use of low grade limestone as a raw material was recorded, and the use of pozzolanic materials such as Hwangtoh, white clay, and roof tile powder as mixing aids to enhance the strength of lime was recorded. In addition, various lime hydration and mixing methods were recorded, and based on re-experiments carried out with regards to this, a physical property evaluation was deemed to be required in accordance with the various types of raw lime materials, lime hydration methods, and mixture ratios. In the early Joseon Dynasty, lime was used for various aspects, but frequent problems were experienced due to lack of supply and poor production techniques. In the late Joseon Dynasty, lime production techniques developed along with mass production. Based on analysis of the manufacturing techniques of Hoegwagmyo lime mortar in the 16^th and 18^th centuries during the Joseon Dynasty, it was found that mixing ratios and the methods described in the ancient literature had been applied. It was confirmed that the mixing ratio differed depending on mixing materials and lime quality. Since the mixing ratio of Hoegwagmyo lime mortar changed over time and it was produced strictly on the basis of a guidebook, it is believed that if continuous scientific analysis of the Hoegwagmyo lime mortar production method were carried out, this would be helpful for ascertaining the chronological methodology of Hoegwagmyo.
