Steel tea pot - I drink a pot every day but last couple pots were both glass and only last a couple months before breaking (both my fault) so upgraded to steel and so far my clumsiness hasn't yet managed to break it
If you are into tea, you might want to consider an electric kettle with variable temperature. Nothing is more of a shame than burning good leaves or having to be limited to leaves that can handle a near boil. It’s tricky & a futz to watch a thermometer for boiling water to a specific temperature for your tea—especially if you are relying on that cup to help your mood & concentration.
