I am restoring handles on a pan. The old handles (made of oak) had a little accident. They were burnt off on a commercial gas stove. My question is: what type of finish do I put on the handles? I am nervous that whatever finish I use it will be more flammable than the bare wood (I am using oak). Also this pan is used in a commercial kitchen and will get hand washed and then steamed so another concern is if I don’t put a finish on the handles then the wood will dry out and crack. Any advice on this would be great! Thanks in advance.
