Borosilicate glass teapot/kettle has been popular in recent years, why?
The value of glass pots and kettles is their ability to brew tea without affecting its taste or absorbing its flavor. They are also easy to clean and care for.
The best glass tea pots are made of heat-resistant borosilicate glass, which contains at least 5% boric oxide. Because the borosilicate glass could bear instant temperature changing from -20°C to 150°C, which makes the glass tougher and capable of standing up to extreme temperatures without cracking or shattering. Obviously, this is an important characteristic for a container that you’ll be pouring hot water into!
Another important factor is the pot design. The lampworking boro3.3 glass could easy formed an attractive and practical teapot or kettle. Features that make a glass tea pot stand out include:
An glass or stainless steel infuser to leave the tea leaves, a ball or other shaped easy carring lid that doesn't fall off easily, a nature smooth spout to keep the hot water out, and a handle that stays cool.
