I had a gen in Bb that I’d put some wax in because I hadn’t any poster putty. Later, I got some putty and it was so much easier to work with I decided to pull the wax out of the Bb. I figured the fipple would be ok to 200 degrees or so, and beeswax would melt by then so into the oven it went.
Big mistake. The fipple completely deformed. However, it is wax free!
water boils at 212 if ya let it cool a bit it is usually fairly safe
oven thermometers (the old spring ones) are designed to be fairly accurate at 350ish (or whatever temp you adjust them to) but they are off the farther you get from there.
Too little too late out of me, I suppose, but I just want to mention how much more viscerally satisfying it might have been stabbing and scraping at it with a pointed stick. The non-melty factor of this aside, of course.
