Korean Antique Octagonal Large Stone Pot Romitate Joseon Dynasty/1392-1897CE

It is a large pot carved in stone in the Joseon Dynasty. It's a shape you don't see very often, but it has a soft and quiet appearance typical of the Joseon Dynasty.
In the photo, ash and trivets are laid out and used to resemble a furnace.

The streaks run through the stone, but when you hold it in your hand, it is solid and solid,
There is no problem in using it.

I think it will be a one-of-a-kind tea furnace, whether it is laid on the floor or in a tea ceremony.
