Flowering tea balls are usually served in containers made of glass so that the flowering effect can be seen. The flowering balls can usually be reused two or three times without the tea becoming bitter. It is unknown if the tea balls are from modern China or much older. So give it a try, you don’t have to buy a glass teapot, just put it in a glass bowl and see if you like it before investing $50, and if you like it go and get yourself one. I am sure you could pick up a glass teapot for much cheaper as a bargin shop (um is it bad that my family calls these shops the shit shops?)
Enjoy a cuppa.
