I'm not trying to bag on anyone, but 350°? Are you sure?
I'm no metallurgist, but I do deal with heat treated parts and 350° isn't much heat at all. If our parts drop below 1000° we'll redo them. I know this all depends on the material but...
Again, I don't want to tell anyone their business, but I seriously doubt this will do anything more than stink up the kitchen and put you in deep kimchi with the wife.
Just one man's opinion, doesn't make it right,
