Glass teapot, glass cups, glass pitcher. Why the emphasis on glass? Because tea is closer to wine than coffee when it comes to possessing a stunning array of color, and no material conveys tea's gamut of hues better than clear glass. Ours isn't just any glass, though. It's borosilicate glass, the kind you may remember from chemistry class. It won't shatter or crack no matter how high the temperature, nor will it cloud after prolonged use in the dishwasher.
