Complex Worlds examines Sin‑ying Ho’s ongoing inquiry into the intersections of ceramics, digital culture, and the material life of information. In this series, clay operates not simply as a medium of form but as a site where data, memory, and cultural lineage converge. Ho hand‑paints traditional patterns, motifs, and symbols, then overlays them with digital decal transfers featuring contemporary signifiers—AI, @, binary code, G5, and microscopic imagery of the Covid virus. These collisions generate hybrid surfaces that expose the frictions and continuities between ancient craft and digital systems, grounding immaterial information within the physical, enduring language of ceramics.
About
Yu Letu
Born in 1962 in Kaifeng, Henan, is a Chinese ceramic artist based in the United States. He is a pioneer in the inheritance, development, and innovation of contemporary Northern Song Guan Ware (Official Ware) culture and art.
Professional Background & Technical Mastery
In the early 1990s, Yu began his career at the Kaifeng Northern Song Guan Ware Research Institute, where he dedicated himself to the research and firing of this historic ceramic style. He systematically studied ceramic kiln thermal engineering and the traditional celadon firing techniques of the Song Dynasty. He mastered core technologies including material formulation, clay body shaping, glazing, and firing for Guan, Jun, and Ge wares. Furthermore, he was instrumental in the R&D of all major scientific projects at the institute during that era.
Academic Contributions
Yu Letu is the only contemporary ceramic artist to have published specialized academic monographs on Guan Ware from both the Northern and Southern Song Dynasties, transforming the craft into a field of rigorous academic study:
-
2010: Published China's Bianjing Guan Kiln, the first academic monograph on the subject since Emperor Huizong created Song Guan Ware.
-
2018: Published Northern Song Guan Ware of China.
-
Forthcoming: The Firing Techniques of Chinese Northern Song Guan Ware, a practice-based "textbook" completed in 2017, to be published by Elephant Press.
Artistic Achievements
His works have been featured in world-renowned exhibitions such as the Shanghai World Expo and Artexpo New York. He holds the record for the most international exhibition participations among Kaifeng ceramic artists and has received numerous prestigious awards.
Craftsmanship & Innovation
Yu is renowned for his "craftsman’s heart," meticulously overseeing every stage from material selection to the final firing. He is a specialist in kiln-transformation (Yaobian) effects using natural mineral glazes. He possesses a profound understanding of the physical and chemical properties of raw minerals at high temperatures, achieving a masterful level of control over both oxidative and reductive firing atmospheres to determine the final glaze color and texture.
