Too bad that there is not the tea master also made of glass! The tea master is just practical, filling pure tea, pour the water up done! I fill the tea then mostly in my glass jug to prevent it as long has contact with the plastic, but that must always decide for yourself! Just enclose it when he's done on the can or cup and let him run off the bottom. Since the screen is white on the inside, I would rather not use it for black ... I can imagine that he will soon no longer looks so appetizing! My screen has certainly no slumbered discoloration although I have sometimes forgotten the tea in the pot, and the screen also often times overnight was already in the tea. The Remove the tea is left somewhat cumbersome, there's no good technique, I gather together with your fingers and the rest I simply rinse out. I would in any case order it again!
