I have a lowball glass that developed a crack along the side earlier this year that I've continued to use since the crack was so small that nothing leaked out. However, after months of continued use and dishwashing cycles the crack now goes from the lip of the glass down about three-quarters and then curves around to another side. It's still sealed, though, and does not leak liquid. I'm getting kind of worried about the crack getting worse, to the point that it'll either shatter in my dishwasher or in my hand. I'll probably just throw it away, but I was wondering if there's a way to fix it since I get bored from time to time and DIY stuff helps pass the time if it's interesting. Is there a home method of repairing glasses that have these hairline fractures?
