How to identify heat-resistant glass?
Identifying heat-resistant glass is no easy task. It is important to observe the glass surface to see if there are any obvious bubbles or flaws. Good heat-resistant glass should have uniform thickness and smooth surface. When you touch it, it should feel firm, not squishy or brittle. Before purchasing, be sure to carefully check the product label to confirm its heat resistance. Only in this way can you ensure that you purchase safe and reliable heat-resistant glass products to avoid danger caused by improper use.
