Tea Bag Steeping in a Glass Pitcher
This photo shows a tea bag steeping in a glass pitcher, with small teacups in the background. Presumably, the tea is going to be poured into small teacups after it is done steeping.
Glass brewing vessels like this have the distinct advantage of allowing you to watch the tea infuse into the water, which allows you to time the steeping based on the appearance, especially if you are experienced with brewing the particular tea in the particular vessel.
