This one is definitely gonna be a looker. There are too many issues with the bowl, that I'm not comfortable cooking on it, just because I think it will deteriorate even more. There is too much rust both inside & outside along with some rust through.
So, it will basically be a preservation for a display piece.
What I've done so far is given the bowl a spray of oil and given it a good wipe down. Hopefully this will stop the rust from progressing.
