Do not use it in a microwave with the wall sealed unless the manufacturer states it is safe. Because the outer wall stays cooler, drinks feel less hot to hold than they are — worth remembering around children. The insulation also means a drink cools more slowly, so pour slightly cooler than you would into a ceramic mug if you like drinking immediately.\u003c\/p\u003e\n\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eAgainst a ceramic mug, double-walled glass holds temperature longer, stays cool to hold and lets you see the drink — which matters for layered coffees and teas. Against a vacuum flask, it is for sitting down with rather than carrying. For a hot drink you want to drink immediately, ceramic loses heat faster, which is occasionally an advantage.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the outside stay cool?\u003c\/strong\u003e\u003cbr\u003eThe insulating air gap between the two glass walls slows heat transfer, so the drink stays hot while the outer wall stays comfortable to hold.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan it go in the dishwasher?\u003c\/strong\u003e\u003cbr\u003eHand washing is safer.
