How to choose glass tea set? The key lies in these three points
The glass tea set is bright and smooth, easy to clean, and can retain the aroma of tea to the maximum extent, but it also has the shortcomings of fragile and hot. Among the many tea sets, many people have a soft spot for glass tea sets. So, how to choose glass tea set?
1. High borosilicate glass is preferred
The glass pot on the market is divided into heat-resistant and heat-resistant. The use temperature of heat-resistant glass is generally "-5 to 70 ° C", the use temperature of heat-resistant glass can be up to 400 to 500 degrees, and can withstand the instantaneous temperature difference of "-30 to 160 ° C". As a tea brewing tool, high temperature resistant and lightweight high borosilicate glass pot is the first choice.
The high borosilicate glass has low expansion coefficient and will not burst when the temperature difference changes suddenly. High temperature and acid resistance also make high borosilicate not easy to precipitate harmful substances in daily drinking water use.
The weight of high borosilicate glass tea set is much lighter than the "raw glass" containing a large number of heavy metal ions, and it looks different from ordinary glass in appearance, and visually separated from the hard and brittle feeling of "raw glass".
High quality borosilicate glass has uniform thickness, very transparent under sunlight, good refraction effect, and crisp knocking sound.
2.The lid should be properly tight
When buying, check the tightness of the lid and neck, too loose is easy to fall (the lid is not tight does not mean that it is an inferior product), too tight may appear stuck, easy to cause damage.
Moreover, the lid is too tight to form a sealed space, when the temperature inside the tea set changes, the air pressure difference can not be balanced, it is easy to burst.
3.Stainless steel filter is best
Stainless steel filter is durable, non-toxic, easy to clean, most of the current 304 stainless steel, few brands will 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.
