Ah, gotcha. I just figured that was a tea stain. Thanks, Steanze!
That looks unusual for a Baozhong... normally the leaves are open not rolled like yours!
Do you still notice the smell after using / seasoning the pot, or is it just the smell of the dust? Thinking that the older pots have had more time to be seasoned, so they may ha e their own smell by now, whereas the new pots still just smell like clay.
