Contemporary ceramic art is expanding its expression areas through the fusion of various genres. After the advent of abstract expressionism in ceramic arts in the 1950s, painting art has had a great influence on the pursuit of post-formalism of traditional ceramics that emphasized functionality. Especially, in ceramic painting, Cheonghwa and Sumukhwa use different expression methods depending on the material, but there are essential similarities. Contingency and speed are expressed with Cheonghwa’s cobalt pigments and Sumukhwa’s water and black ink('meok'), respectively, and they both contain the Xièyì(寫意) ideology that emphasizes the beauty of formality(形式美) and content of art(內容美). Xièyì is similar to 20th century Expressionism painting that emphasizes a form of the senses nd the subjective interpretations of the artist. Traditionally, the Cheonghwa technique has been developed under the influence of the Sumukhwa technique, and examples can be seen with the advent of Chinese Cheonghwabaekja (blue and white porcelain) in the 14th century. To understand ‘Sumuk-Cheonghwa’, it is necessary to have a sufficient understanding of the two fields of Sumukhwa and Cheonghwa. This study is to establish the basis of the modern expression of ‘Sumuk-Cheonghwa’ using the Sumukhwa technique and to expand its application to modern ceramics. To do so, it is analyzed by focusing on ‘Cheonghwa Bunsu’ and ‘Cheonghwa Gongpil.’ In the introduction, the theoretical backgrounds of Sumukhwa and Cheonghwa expressions are described, and the rationale and similarity of expression techniques are examined through Expressionism art and Sumuk-Cheonghwa’s Xièyì to clarify the theoretical basis. In the main body, the expression process of representative Cheonghwa techniques is introduced, and artists who are consistent with the thesis of this study are presented to analyze their characteristics. Through this study, it is expected to provide an opportunity to discuss the theory and practice of systematic ceramic painting and to promote the establishment and expansion of new contemporary ceramic art.
