What is Tensei? Origin and etymology

Tensei, as the name suggests, refers to the "blue of the sky," especially the color of the clear sky after the rain has stopped; it is a quiet and profound shade of blue.

The name of this color was immortalized by the celadon ware known as "Ru ware," produced during the Northern Song dynasty in China. An anecdote tells of Emperor Huizong, seeking the ideal blue, ordering, "The blue of the sky after the rain, the color of where the clouds part—that is the color of the vessels to be made from now on." This legendary passage solidified the image of the color sky blue.

The historical background of Tensei

The color "sky blue" was most highly valued during the reign of Emperor Huizong of the Northern Song Dynasty (1100-1126), who deeply loved the arts. He was deeply devoted to Taoism, and its philosophy greatly influenced his aesthetic sense. In Taoism, blue is considered a sacred color symbolizing the East, the beginning of life. It is believed that the Taoist philosophy, which dislikes ostentation and values natural and effortless beauty, provided the fertile ground for the serene and understated "sky blue" of Ru ware.

Because Ru ware was produced only for the imperial court for a mere 20 years, it is said that fewer than 100 pieces exist worldwide, and it is known as the "legendary celadon." Due to its rarity and sublime beauty, it was treated as a treasure by emperors of later eras, and Emperor Qianlong of the Qing Dynasty loved this color so deeply that he had poems inscribed on Ru ware pieces that he owned.

Tianqing in Chinese Art and Crafts

The artwork that best symbolizes the color of sky blue is, needless to say, "Ru ware celadon." Its unique blue color is created by a technique called "reduction firing," in which trace amounts of iron in the glaze are fired in a kiln under low oxygen conditions. The surface of the finished piece develops a fine crackle pattern called "kannyu," which becomes a landscape and adds to its profound beauty.

Furthermore, in the realm of fashion culture, it is said that literati and aristocrats of the Song dynasty favored such subdued shades of blue. The celestial blue quietly reflects the Song dynasty's aesthetic sense, which avoided flashy decorations and valued the quality of materials and refined colors.

When the rain passes, the blue clouds break down, and the future is full of complexions.

― Song Huizong
