Constructing Ancient Korean Celadons for Modern Firing Cycles
Ancient sherds and samples collected from Gangjin and Gimjae celadons (Koryŏ period, 918-1392 CE) were previously analyzed to determine the firing conditions and to evaluate the body and glaze chemistry. Those results show that ancient samples were fired with three- or four-day long soak time at temperatures between 1000°C – 1200°C. The firing conditions of ancient Korean celadons produce a deep glaze-body interaction zone that is responsible for the optical characteristics of the glaze. To mimic the optical effects of ancient Korean celadons in modern firing cycles, the depth of the glaze-body interaction can be obtained using a two-layer glaze system. A two-layer glaze system was created that mimics the microstructure observed in the glaze-body interaction zone of the ancient samples. Color analysis by spectrophotometry, as well as chemical content and distribution mapping via SEM/EDS were used to evaluate the two-layer glaze system. Analysis of these data indicate similar optical effects and chemistry as presented in ancient Korean celadon samples.
