Found this nice cast iron teapot from a flea market. It’s enameled inside (of course) and it has a stainless steel tea sieve. Needs a bit of soda boiling to get rid of tea residue inside. I guess I should also check the enameling for lead (some of the old ones can have lead in them I think), though I’m pretty sure it’s safe. It doesn’t seem that old.

–Edit–

shift -> sieve (used the wrong word first)
