Earlier today I was disassembling an old toaster oven to salvage the heating elements for a vacuum form table I am currently working on. Unfortunately, I broke one of the glass tubes that holds the heating coils, I was curious as to if anyone knew of a good high heat adhesive that would fix it? By high heat I mean around six hundred degrees or so, not that I'll be working with heats that high, but more of a just in case type of situation.
