Hello everyone! I was just wondering if anyone has a surefore way to see of glass is tempered. I have drilled a couple 40bs but there are some 90s and 120s for sale around me and not all are drilled or even drilled where I would like them. I know its much thicker glass than the 40b but I wanted to see if there is a good way to tell.
