The borosilicate glass teapot set is a tea time angel: kettle, infuser & warmer in one!Either use a separate tea kettle to boil water or take advantage of the practical feature of this glass tea pot and place it directly on your stove (electrical or gas/please do not use on induction cooker stove) or in the microwave. Just make sure to remove the stainless steel infuser and lid in advance. Once your water is boiling, it’s time for the tea pot strainer to bring it on. The removable infuser lets you steep all kinds of tea, without leaving any bits floating around. After removing the infuser, just add the tea pot lid again and indulge in your warm beverage - thanks to a well-designed spout, you can pour your tea without any spills!
