Glass cookware is translucent and smooth, easy to clean, can retain the tea fragrance to the maximum, but it also has shortcomings such as fragility and hot hands. Among the many tea sets, many people have a soft spot for glass tea sets. So, how to choose a glass tea set?

Borosilicate glass is preferred
Glass tea is heat-resistant and heat-resistant. The heat-resistant high borosilicate glass has a very low thermal expansion coefficient, only about 1/3 of that of ordinary glass. It can withstand the huge temperature difference of -20℃-150℃ rapid cooling and heating. Not easy to burst, suitable for high-temperature tea brewing, and the quality of the tea can be heated and brewed.
Therefore, from a safety point of view, high borosilicate glass is the first choice for teapots, tea cups and fair cups. The body of the elegant cup must be high borosilicate glass. There are currently three choices of food-grade PC, 304 stainless steel, and high borosilicate glass for the inner tank. , Are safe and healthy materials

The tightness of the lid should be appropriate
When buying, check the tightness of the lid and the neck of the pot. Too loose and easy to fall (not tight does not mean it is a low-quality product). Too tight may cause jamming and damage.
Furthermore, if the lid is too tight, a sealed space will be formed. When the temperature inside the tea set changes and the air pressure cannot be balanced, it will easily burst.

Stainless steel filter is the best
The stainless steel filter screen is durable, non-toxic and easy to clean. At present, most of them are 304 stainless steel, and few brands use more advanced 316 stainless steel.
In addition, it is not recommended to use plastic filters, because substances harmful to the human body may be precipitated at high temperatures.
Even the heat-resistant high borosilicate glass cannot avoid the common problems of being hot and fragile. If you use a glass to make tea directly, it is recommended to buy a double-thickened version or a heat-insulating one.
