Which one is better, purple sand teapot or Ru kiln teapot?

It has good air permeability and fully releases the ingredients of tea leaves. It will not go rancid overnight in summer. 3. It has good thermal and cold denaturation and will not burst due to sudden temperature changes. 4. The longer the purple sand is used, the better. The color of the pot will be more radiant, the charm will be gentle and elegant, and it will have a certain ornamental value. 5. Purple sand contains high iron content and is good for health.

This is also better. If you want to be more artistic , the recommendation is still purple sand, buy purple sand and look for the pot history directory
