Teapots are challenging vessels to make because a good teapot must balance esthetics with function. No matter how pretty a teapot is, it would not be well used if it drips a lot, if the weight is not well distributed, if the spout keeps getting clogged, if the lid doesn't fit, if it is hard to clean. After all, enjoying a cup of tea begins with the selection of quality leaves and the care taken to brew it, in one's favorite teapot.
