Sorry for the confusing title. We have a circular table (an old etched wheel) that is 3ft in diameter. It also has 4 rubber spacers along the diameter. I want to get a tempered glass tabletop for it. Our old one broke when someone placed a hot dish on it. The old glass had around 3ft 6inch diameter and about quarter of an inch thick.
My question is this: Would a 12mm thich, 4ft diameter tempered glass tabletop be safe?
Our table would end up having a 6 inch glass ring around our current table. Would that be safe for dining purposes?
Here is a photo of the table and a photo of the rubber stoppers.
