When is the tin pot?

The late Ming and early Qing dynasties were the heyday of tin ware, and there were many traces of wine scalding in this era. Professional dating is to study tin pot shell: because tin is not affected by air at room temperature, if an antique tin container is left in a dry environment for a long time, its appearance will not change much except that its luster is not as strong as that of a new tin container.
