To begin with, we must distinguish between glass teapots for serving and heat-resistant teapots that are also used for preparation. The serving teapots are more like tea carafes. They are decorative and bring grace to the service. They can be used to gradually cool your infusion in the refrigerator. This type of teapot has the advantage of being transparent, but beware of thermal shocks! Fortunately, nowadays, the vast majority of glass teapots are heat resistant. This has significantly changed our perception of the glass teapot.
