Abstract

Traditional Korean roof tiles stand out as a key element in Korea's distinctive architectural style, making it crucial to safeguard their production techniques and maintain their use. In line with these preservation efforts, this study explored the quality standards and evaluation methods of these Korean roof tiles. Experiments were carried out on three roof tile types, following the evaluation method outlined in the standard specifications for cultural heritage restoration. Additionally, chemical and microstructural analyses were undertaken to grasp the factors influencing tile performance. The results of these experiments revealed that the primary factor influencing roof tile performance is not the molding method, but rather the firing conditions. Consequently, the current standard, which classifies quality based on the molding method, is overly lenient toward handmade roof tiles fired in modern kilns. Regarding the frost resistance test method, which assesses the most critical aspect of roof tile performance, it was found that subjectivity can be involved in visual inspections, and 10 freeze-thaw cycles may not accurately gauge frost resistance. Therefore, the development of a more objective and efficient quality evaluation method is deemed necessary.
