Not only should you always preheat your teapot, but there's even a trick that will prevent your teapot from suffering a thermal shock. Start by pouring the off the boil water on the lid of the closed teapot (see above). This safely increases the temperature of the teapot. Then, in a second step, remove the lid and pour the water in the teapot. Be especially cautious to do so in a cold room or with an older teapot that hasn't been used for a while.
