Borosilicate glass is a type of glass that is known for its high durability and resistance to thermal shock. It is made by adding boron oxide to the traditional glass mixture, which increases its resistance to sudden temperature changes. This makes it ideal for use in tea sets, as tea is often served at high temperatures and the glassware needs to be able to handle the rapid changes in temperature.
Borosilicate glass tea sets are also preferred by many tea enthusiasts because they do not interfere with the flavor of the tea. Unlike plastic or metal containers, borosilicate glass does not impart any unwanted tastes or odors into the tea, allowing the true flavor and aroma of the tea to be enjoyed.
Another advantage of borosilicate glass tea sets is that they are very easy to clean. They are resistant to stains and do not absorb any flavors or odors, so they can be quickly and easily washed with soap and water.
