My boss told me to never use a glass cutter on a cold windshield

He said it last winter when we had a big job in Buffalo, and I thought he was just being extra careful. I tried it on a frosty back glass last week because I was in a rush, and the whole thing cracked in a crazy spiderweb pattern before I even got halfway. It cost me the piece and a lot of time to clean up. Has anyone else had a temperature surprise ruin a cut?

Seriously? I've cut cold glass before and it was fine. Maybe you just got a bad piece or pressed too hard.

Oh man, that's lucky! I had the total opposite happen once. I was trying to cut a cold bottle for a craft thing and it just exploded into a million tiny pieces, scared me half to death. It wasn't even about pressing hard, @lucast81, the whole thing just gave up. Ever since then I get nervous and run the glass under warm water first, just in case. I guess the quality or the type of glass really makes all the difference.

Yeah that's a thing with a lot of stuff now, not just glass. It's like the build quality is a total gamble. You can buy two of the same exact thing and one lasts forever while the other breaks right away. I see it all the time with cheap tools or even phone chargers. Makes you wonder how anything gets made the same way twice.
