About Us


Tenmoku, also known as JianZhan, a type of black glazed tea bowl, hails from Fujian, China. It was first produced during the Song Dynasty (960–1279) and is famous for its natural glazed patterns and the iron-rich clay, which is the foundation of every piece. The textural depth and visual glaze patterns reveal themselves randomly at high-temperature wood-firing, which makes it a unique (or impossible to duplicate) piece. ChromWare has been studying and mastering tenmoku pottery​, an ancient art, for more than 20 years. Our tenmoku tea sets are utilizing the original Song Dynasty techniques, which are 13 steps, and modern day creativity and skill. We hand-make each piece with iron-rich clay (9% Fe content) and produce the recognizable hare's fur, oil spots, and iridescent tenmoku glaze patterns by wood-firing in kilns at 1300ºC. Our tenmoku tea cups are known by collectors around the globe because they reflect China's ceramic history and modern form in tea wares.ChromWare partners with global cultural leaders: Shanghai's Waldorf Astoria uses ​Tenmoku tea cups​ in VIP rituals; Kyoto's Fujian teahouse crafts custom ​Hare’s Fur bowls. Taipei's Eslite Bookstore pairs JianZhan with ancient texts, while Shanghai's Duoyun sold $150k ​Tenmoku sets​ in a day—bridging tradition through art.
