If you watch my video, no, I do not normally boil my tea while brewing it, but I thought the video would show up better that way. The video shows how the handle stays cool, but I can't quite lift the lid because the knob is hot.
This pot will boil one full liter without boiling over or coming out of the spout at all. As for dripless pouring, you can MAKE it drip if you try to barely dribble it out of the spout, but you wouldn't do that. Just pour it slowly or normally and not one drop will dribble. The tea filter-strainer works perfectly - it goes in and lifts out easily. The lid fits and stays in with or without the filter in place. I didn't get any residue in the bottom of the pot I brewed. If you use your pot on the stove, I would have a silicone hotpad or something nearby to set the pot on, so you don't cause thermal shock and risk breakage by setting hot glass on a cool surface. The instruction leaflet is well done and clear - do take a minute to read it before use, to protect your pretty pot and keep yourself safe. It came well package and looks very nice - I would be happy and proud to give this as a gift!
