Are more than ten high-boron glasses poisonous?



Recently, I bought a glass of more than ten pieces. Every time I make tea, I always feel a little strange smell. I still feel a little uncomfortable after drinking. If you suspect that there is a problem with the cup, you can see that most of the glasses that JD claims to be lead-free are more than 50 or 60. Show All

I started to export glass products after graduation from university, and it has been more than ten years now，  glass cookware   .
According to glass material, lead-free crystal glass, ordinary soda-lime glass, high-borosilicate glass, tempered glass, etc
 
 
 
The high borosilicate glass is resistant to high temperature and will not crack when the temperature difference is large (take out the boiled water in the refrigerator). There are both machine-made and artificial cups. (My brother's bar opened, and I sent the water cup from the factory)
 
 
 
Lead-free crystal glass is transparent, higher than ordinary soda-lime glass and more expensive than soda-lime glass. The hand-made lead-free crystal red wine glass is very exquisite, with thin wall and thin stem, which can be compared with the large brand crystal glass from abroad. (The cousin who sells red wine in Shenzhen used to wholesale crystal glasses downstairs for customers. The most common one was 60. Later, she asked me to help distribute it from the factory, which saved a lot of money.)
 
 
 
Ordinary soda-lime glass, mechanical and artificial cups are available. It is not resistant to high temperature as crystal cup. Even if it is not resistant to high temperature, it will not affect its use. For more than ten years, we have been using artificial sodium-calcium glasses. Except for accidentally breaking them, we haven't seen any self-fried ones. Once, my husband put the glass pot containing water in the refrigerator, and took it out the next morning to pour the freshly boiled water, and it burst. In more than ten years, I have encountered such a self-bombing due to improper operation.
 
 
 
Speaking of safety, it is safe to use any of the above glass glasses. We have done all kinds of tests on our exports, and there are no problems in the United States and Europe.
 
 
 
When buying, we should pay attention to the decoration on the glass. Although the colored cup can also pass the food safety test, I have never used it myself. The colored cups I use are all colored. The so-called color is the color of the glass itself. This kind of glass is as safe as open glass. If there is flower paper or other decoration on the glass, it will not be within 2 cm of the cup mouth, which is to avoid touching the mouth. This part with decoration is not easy to test. Of course, except for Phnom Penh and Platinum Penh. Phnom Penh and Phnom Penh are made of real gold and real platinum. It's no problem how to test them.
