Can extreme cold crack glass?

I don't know about you but here in Wisconsin we have windows that have one very thick pane of glass, another pane of glass, a screen, and heavy weatherstrips all around and this morning I woke up with a huge crack in my window. It's not in a spiderweb pattern, no its not from me throwing something at the window (plus when i went to sleep I saw no crack) and it's weird, it runs from the bottom of the pane to the top, but it doesn't go all the way through the glass, it's on the thick pane, on the side away from my room. I'm thinking it got so effing cold that the cold cracked the window :o

I hope i don't get in trouble

Maybe if it's really warm in your house, and it get's really cold outside very fast at night. I'm not sure though. I've cracked a couple coffee pots from washing the pot too soon after making coffee.

Anyone else know for sure?

Not for sure, but that makes sense.

Yes the same thing happens if the glass gets too hot and the thickness of the glass.

if i put water in a glass cub and set it in the freezer, set it to high it will crack the glass cub yes ciaxhieu

Most likely not, the water would freeze, but the top is open so the ice wouldn't just shatter the glass (unless the cup is sealed)

In the very tip top of minnesota in the Iron Range trees have been known to expload from quick changes in temperature.

Its pretty loud apparently. I have never seen it happen as I live in the twin cities close to the southern border but all of the old guys in my family who grew up in the north talk about it from time to time.

To be honest I dont believe it myself. Apparently its like an urban legend for old hunters or something. I think its probably a mixture of hearing gunshots and seeing a tree that got hit by a bullet or something.

Then again there are some crazy temp changes in this state, it can go from 50 degrees to like zero or less over night once winter decides to come around.

Maybe I guess.

but every explanation involves rapid temperature change. (i think) so how could that have happened to his window?cliff122316

Well it is possible, but like i said in an earlier post, i think it is more likely that the ground shifted causing a crack.

yeah maybe the ground shifted, I have to buy a new window now :(

By the way, in the book Brian's Winter trees explode due to water seeping under the bark and hardening into ice

Yes extreme changes in temperature can break perfectly good glass, but it's unlikely your window went through these changes since I believe the difference in temp is over 100 degrees. What's more likely is that you had a chip in your window, or a hairline crack, and when it got cold it caused it to make a larger crack much like the one you described.

So technically the cold did crack your window, but it was the cold and the previous chip/crack, not just extreme cold.
