I waited a few months to post this. This glass clearly wasn’t tempered properly. We knew that there would be some pieces that shatter (normal)  but this stuff is very dangerous. Every time we have a fire there are a few pieces that shatter (explode) more than they should. We had an instance recently that prompted this review. A piece shattered far enough to land on my husbands arm and melt into the fabric of his clothing. Dangerous!! Unfortunately, this is the only photo I have of how far the glass cans shatter from the fire pit.
