What material? My teapots are ceramic and tea discolors them.

This is a stage in traditional Chinese tea ceremonies (of which there are a few I believe). Some involve pouring excess water or tea over a clay lot to cure the clay. Not sure if that actually works or is just ritual.

Best I can glean through random forum/blog posts-
The Yixing clay is porous and absorbs the tea oils and tannins to form a patina on the surface.

So, the pots are actually discolored by the tea, if the pot is light enough for you to notice. That's what I thought. Thanks Enigman.
