I'm working on a project for my daughter and don't know how to finish it. It's a turning designed to hold a tea bag after steeping. The bag will be really warm, 150 to 180 degrees or so with liquid coming out. Sometimes the bag could get reused so it has to remain food safe.
I know all finishes are supposed to be food safe once cured but I wasn't sure if heat affected that. Should I use a clear epoxy? Cyanoacrylate? Walnut oil? Whatever is used would have to harden due to the puddle of tea that will form (and need to be cleaned with warm water and mild soap).
