karma's post got me looking for a tetsubin again. I have been on and off with my search for one. Some tetsubin has a wax inside, some do not. Anyone wants to chime in if the inner wax is a plus or minus? I found a used one for 150-200 usd range, but the inner bottom may have some mineral built up. Do you think this is cleanable/usable?
Looks pretty usable you‘ll just need to boil used or cheap tea leaves a few times to remove some of the rust and reseal the surface. Earlier in another thread I
describe the process I’ve used to get a used somewhat rusty tetsubin back into shape. I’ve not heard of any wax being used inside a tetsubin, that sounds counterproductive. Urishi is sometimes used on the outside to seal the exterior surface, and also on the bottom to plug up casting holes. The inside is heat sealed, similar to gun blueing, and should not be raked or brushed with any metal abrasive brush, this will further degrade the seal. Some members have used citric acid to remove mineral deposits. Looking forward to hearing which method you use.
