Coating inside my new tetsubin water kettle

I just purchased a nice tetsubin and noticed a shiny lacquer looking substance on the inside of it. I know it’s not enamel but am wondering what it is. I’ve been in touch with the seller and he said it’s a rust prohibitive substance that wouldn’t affect the taste of the boiled water after the break-in period of boiling numerous batches of water.
Has anyone experienced this in any of their tets and is it no big deal in the performance of it? It’s a nice piece of iron and I’m looking forward to boiling some delicious water in it.

Sounds like Urushi lacquer. Some Tetsubin have that, although it defeats the whole purpose of a Tetsubin to add iron to the water...

Yep, Urushi.

Does it affect the taste of the water? Can it eventually flake off? I guess the iron benefit of the water is extremely diminished or gone completely? Thank you.

Yeah the benefit of a Tetsubin is gone. It might flake off after a long time... I got a vintage one where it’s gone by now but no idea how many years or decades that took.

I recently got a used tetsubin. I was puzzled for a long time about coating inside. It looks similar to the texture in your photo. Most of the coating came off from mine aside from the side wall. You can look back at the tetsubin section to find the images
