What is Tang Sancai (Tang Dynasty Three-Colored Glaze)? | Characteristics and History of Three-Colored Funeral Artifacts Fired During the Tang Dynasty.
Ru ware refers to the kilns that produced primarily celadon porcelain, serving the imperial court from the Five Dynasties period to the end of the Northern Song Dynasty.
The term Ru ware can refer not only to the kilns themselves, but also to the celadon porcelain produced.
Because production lasted for only a very short period of about 20 years, Ru ware pieces are extremely rare, and it is said that fewer than 100 pieces are recognized in museums worldwide.
While the term \\\"Northern Song official kiln\\\" generally refers to Ru ware, much about it remains shrouded in mystery.
