생활도자기에 사용된 코발트 안료의 청화색 비교분석 - Blue 계열을 중심으로

Abstract

Background In the history of ceramics around the world, the blue-and-white porcelain can be represented as a representative symbol of color in ceramics. Chunghwa was a groundbreaking method of coloring at the time when it was developed, and has become an essential technique of ceramics coloring, and continues to this day. The purpose of this study is to quantitatively color and analyze the chunghwa colors in the ceramic tableware currently on the market to establish basic data on the colors. Methods We selected the six ceramic tableware brands whose products’ colors can be measured on the spot: Korean porcelain, Hangnam porcelain, Royal Copenhagen, Denby, Rostrand and Gien. The products were visually categorized according to the KS A 0011, and their Hue, Lightness, and chroma were compared based on the color values using the color space of CIELAB. Result The result showed that most of the products were distributed between the red direction of a* and the blue direction of b* and fell within the scope of the KS standard color range of BG, B and PB. Also, although many of the products had low lightness and chroma, some of them had a wide distribution from medium to high chroma. Conclusion Based on this study, the standard of Korean industry can also be applied to the ceramics industry as basic data of Korea, and the direction of modern color planning of chunghwa can be set by utilizing it in the color planning process of the Korean ceramic brand. Also, we expect the data provided in this study will help ceramic Tableware brands to develop a new chunghwa color.
