+1 on the nail polish...
Take this with a grain of salt because I do NOT know if the heat and/or heat exposure time in a firing sequence would be long enough to do the same thing - but I once was dumb enough to try and solder something that I'd previously glued together with cyano-acrylic glue. Super Jet it was I think, but same thing as Krazy/Super glue. It liquefied, sizzled, and spit off this little puff of gas and nearly choked me to death while burning my eyes out.
Wouldn't want a puff of that coming up out of my chamber, for sure. No long term problems but I was miserable and wheezing for about an hour. Do NOT burn anything with super-glue on it outside a fume hood!
PS - if you're a fly tyer like me, head cement works well too. But if you can tell me the difference between it and nail polish, you're a better man than I.
