Is the high borosilicate glass filter screen of Bear Health Pot easy to break?
No. High borosilicate glass is not fragile. High borosilicate glass is made by using the conductivity of glass at high temperature and heating inside the glass to melt the glass. It is processed by advanced production technology. Because the coefficient of linear thermal expansion is (3.0. 1) times 106 per k, it is also called borosilicate glass 3.3.
