I have tried to find a definitive answer to this, but do not see it anywhere, so forgive me if this is noted elsewher, but is cured HXTAL-NYL-1 epoxy food safe? For example, if it is thinned and used to fill micro-cracks in blown glass cups, would it be safe to drink from? And if so, would this be affected by higher temperatures (e.g. boiling water), since the epoxy breaks down @ 500 degrees?

HXTAL has never been tested or approved for food safety so it's never really advertised as such.

It should technically be food safe, but without FDA approval it cannot be used and advertised as such.
