Colors of Ceramic

"After rain, the sky clears—make this color for me." This legendary quote from Emperor Huizong describes Ru kiln's Sky Cyan. Using agate in the glaze, Ru ware achieves a jade-like blue that shifts subtly with light. Only ~70 pieces survive, each priceless.

Cobalt Blue is China's most globally influential color. In the Yuan Dynasty, Persian cobalt met Jingdezhen porcelain clay, creating stunning blue-and-white ware that spread along the Maritime Silk Road. A Yuan Dynasty blue-and-white jar sold for ¥230 million in 2005.

Moon White was one of the Song Dynasty's most elegant colors. Emperor Huizong reportedly dreamed of the sky after rain and ordered Ru kiln artisans to create this faintly blue-tinted white glaze, embodying the Song aesthetic of subtle beauty.

Iznik Blue is one of the Ottoman Empire's most glorious artistic achievements. 16th-century Iznik pottery fused cobalt blue, turquoise, red, and green. The secret was a unique quartz base (80% quartz) giving glass-like brilliance. The Blue Mosque's 20,000 Iznik tiles radiate deep blue in morning light.

Persian Blue is the most iconic color of Islamic art. Isfahan's mosques, "half the world," have Persian blue tile domes gleaming like sapphires in desert sun. The complex process involves grinding cobalt ore and firing at 1200°C. Persian blue traveled the Silk Road to China, inspiring blue-and-white porcelain.

Japanese indigo is celebrated as "Japan Blue." Hokusai and Hiroshige's ukiyo-e extensively used this deep blue, stunning European artists after Japan's 1853 opening. Van Gogh collected Hiroshige prints, and "The Starry Night"'s swirling blues were directly influenced by "The Great Wave off Kanagawa." The 30+ step dyeing process transforms fabric from yellow-green to deep blue through oxidation.
