Benjamin6264It's a bad idea but not super dangerous. All (correct me if I'm wrong) of these on the market are just double walled, not vacuum/air purged, so when overheated you may get some oil canning or a leak at the weld/seal. Definitely bad juju with a vacuum purged vessel, though.

StepbystepI would think air is more dangerous than vacuum, since it wiĺl expand when heated.

That said, the insulation is much, much better than single wall; you can pour boiling water in it while holding it by the "body" and won't get burned (unless you spill some - use the handle just in case)
