Twisted embryo porcelain is an ancient ceramic handicraft in China, which was made from the late Tang Dynasty to the Five Dynasties. Its uniqueness lies in that mud blocks of different colors are twisted together to form a unique carcass texture, which is also called "twisted tire" or "twisted mud".

The manufacturing process of twisted-tire porcelain is complex, and it is necessary to twist mud blocks of different colors together to make the required carcass, and then make exquisite porcelain by means of firing and other technological means.

Because of the difficulty in making twisted-tire porcelain and low yield, twisted-tire porcelain was regarded as high-grade porcelain in ancient times and was a special product for royalty and nobles. Nowadays, the twisted-tire porcelain has become a classic of ancient ceramic art in China, and is known as the "gentleman in porcelain".
