After moving into "loose tea", I bought a pretty teapot.

Problem is, it takes me over an hour to drink a pot of tea.
By then, the tea is lukewarm or cool.
I've even tried a "cosy", but it really doesn't help too much.
A friend has suggested using a thermos after the tea's been brewed.
But that sort of defeats the idea of "the pretty teapot".
