Nicely potted Chinese Sung Dynasty (AD960-1279) tea bowl, well known as Tianmu tea bowl. Tianmu tea bowl was originated from Tianmu mountain, China during Sung Dynasty and used by monk for tea drinking. It was introduced into Japanese culture by merchants and monks in the same period, also named as Temmoku. The firing flaw and other irregularities is normal and a good sign of its authenticity. The foot is unglazed and intact with beautiful coral remain. Authentic shipwreck item. We have few more for sales but non is alike.
