Abstract

According to the principle of prioritizing the preservation of the value of cultural heritage assets stated in the Cultural Heritage Preservation Act of Taiwan, monuments should be restored to their original appearance. In the restoration of monuments made of granite – one of the most commonly used material in Taiwan’s heritage buildings – the same or similar type of granite is chosen and then processed using a technique that is similar to the original but distinguishable from the original work as a principle. However, comparing granite materials has a major constraint – samples often cannot be directly obtained unless the granite item shows severe damage or breakup, leading to difficulties in conducting a composition analysis. By integrating traditional and scientific methods, this study developed a nondestructive image identification system for analysing granite items.
