국내에서 생산되는 화강석 중 하나인 거창석은 대부분 회백색 계열이며 컬러석재의 경우 대부분 고가로 수입되어 판매가 되고 있다. 본 연구에서는 컬러 화강석 제조에 관한 연구를 수행하였다. 거창석 표면에 금속촉매를 도포 후 화강석 내부로 금속입자를 침투시킨 다음 열처리를 통해 거창석의 색을 영구히 변환 시키는 연구를 수행하였다. 금속촉매 침투시에 함수발생기(function generator)를 사용한 경우와 사용하지 않은 경우 시간에 따른 침투 깊이와 침투 현상의 차이를 분석하고 검정, 빨강, 갈색의 색상에 따른 침투깊이 차이 또한 비교하였다.

In this study, the degradation properties by temperature stress of $Araldite^{(R)}$ rapid-curing epoxy resin used for inorganic cultural heritages, was identified. The tensile and tensile shear strength of durability decreased for 12,624 hours at temperatures of $40{\sim}60^{\circ}C$. In terms of stability of external stress and temperature, the slow-curing epoxy was superior to the rapid-curing epoxy, and cultural heritage conservation plans should therefore consider the strength and stress properties of restoration materials. Color differences increased for 12,624 hours at temperatures of $40{\sim}60^{\circ}C$, and glossiness decreased. Both color and gloss stability were weak, which necessitates the improvement of optical properties. Thermal properties (weight loss, decomposition temperature, and glass transition temperature) of adhesives are linked to mechanical properties. Interfacial properties of the adherend and water vapor transmission rates of adhesives are linked to performance variation. For porous media (ceramics, brick, and stone), isothermal and isohumid environments are important. For outdoor artifacts on display in museums, changes in physical properties by exposure to varying environmental conditions need to be minimized. These results can be used as baseline data in the study of the degradation velocity and lifetime prediction of rapid-curing epoxy resin for the restoration of cultural heritages.
