The support of the black copper silver cover and the pot cover
I only learned about this term recently.

The main function of the cover is to place the lid. For the black copper and silver, I personally think that its playing value is better than its functional value; the black copper and silver as the supporting function of the cover is no problem, but its own metal material characteristics, And the expensive price, it is difficult to make it play the practical function of the tea table. (For local tyrants, it is free) (customizable)
