I look glass things over pretty good as soon as they come out of the box. I check for chips on the smooth edges, broken but glued back on handles and obvious other flaws. The way this one crumbled, I can't imagine anyone getting away with cracking it in any other way without it doing the same thing, but to be sure, you just never know. I would think twice now about owning a larger piece of this stuff. I still have one jug that is mine that I have washed with no issue. I will be EXTRA careful about doing it again in the future. I mean, if you collect any kind of glass and have it sitting out, eventually you need to give it all a good rinse. I learned this lesson well. 🙂
