Abstract
Celadon shards from Gangjin and Buan were analyzed for their color, chemistry and microstructures. They exhibited similar chromatic characteristics in a CIEL * a * b * analysis. All of the glazes assessed showed comparable compositional areas, while the bodies from Gangjin shards had higher RO2 concentrations. A high degree of similarity was also noted in the microstructures of the glaze and bodies from both regions. Anorthite crystals appeared in the glaze layer, and phase separation behavior developed around these crystals. This may have been caused by the glaze chemistry and the sintering process given the lengthy heating and cooling time. A Raman analysis indicated higher isolated SiO₄ unit (Q?) values for the Buan samples. This can stem from the higher firing temperature or the longer sintering process.
