How much do you know about high borosilicate glass food storage containers?

What is high borosilicate glass? Are there different grades of borosilicate glass?

High borosilicate glass is a kind of glass with strong refractory performance, which is an important material for manufacturing high-durability glass containers and belongs to food-grade glass. Most of glass food container manufacturers use high borosilicate glass to make high-grade glass food storage for the kitchen, which is popular in the market.

High borosilicate glass can be divided into two types: high borosilicate glass and low borosilicate glass, among them, the most frequently used and the best in the food storage containers is high borosilicate glass.

Compared with ordinary glass, high borosilicate glass contains more boron trioxide and silicon dioxide than ordinary glass, and the boron content can even reach 14% and the silicon content can reach 80%. The silicon content of ordinary glass is about 70% (ordinary glass generally does not add boron, but sometimes up to 1%), and high borosilicate glass is no toxic and can use in food storage because of its mechanical properties, thermal stability, water resistance, alkali resistance and acid resistance, etc.

How can you tell if the glass is borosilicate?

1. Put your glass container in the refrigerator after 24 hours, and pour it with hot water of 100 degrees. If the glass container bursts, it is definitely not high borosilicate glass.

2. High borosilicate glass (expansion coefficient is 3.8*10-6 K, boro ≥ 14%), the borosilicate glass can be used in oven, microwave oven, freezer, dishwasher. The high temperature of this glass is 580°C. This means that the borosilicate glass container can be put in the oven and heated to 580°C. Thermal shock is 120°C. Thermal shock is a sudden change in temperature. We usually do the test as follows:

Heat a borosilicate glass container (without lid) to 140 °C in an oven and place in the oven for 30 minutes, then immediately place the glass container in water (20 °C). High borosilicate glass containers will not break.
