Change in temp???

bottle_head9 · Sep 1, 2009

I found some damage on four of my bottles that wasn`t previously there.I live in New England and burn wood, can the change in temp and humidity cause bottles to crack.I know cold /hot water can, but just sitting on the shelf?Has this happened to anyone else?How much does it affect value?

Yeah, I've had Lobey's experience bringing home a freshly dug bottle in the spring (chilly day), and Joe tried to wash it and it just cracked. Now we let them come to room temp. You would think I would have learned my lesson on temperature changes when I once threw a computer out the window into the deep snow. Had to use my metal detector to find it LOL. Long story, but don't make me angry lol. BTW, I just let the computer warm up and it was fine.
Anyway, I will have to keep this in mind at my house because it can get very cold if we are not home. We use a wood stove, so the temperature can be freezing in the morning or if we are out all day, then very hot at night. I should check my bottles to see if this has happened yet!

To crack from temperature, there normally needs to be a potstone, area of slag or other impurities contracting and expanding at a different rate.. When digging in winter, I've had bottles " pop " being brought up to 0 degree air from 50 degree soil and also when bringing them inside from the cold. It is alarming that you had 4 become damaged as it is not a common occurence. There are jerks that will soak damaged areas in oil to make the damage dissapear until a bottle is sold. I hope that isn't the case.

I have also found that dug bottles will often display damage that wasn't seen after they have had a few days to completely dry out after being dug and washed.

I've been cleaning a damaged bottle with a crack in the back, put a little warm water in it, plugged it with my thumb, started shaking, and the whole thing blew up in my hands. I guess the pressure from the warm air expanding inside was too much for the poor thing to handle. Now I use only cool water and even then I'm worried it's gonna damage the bottle. Hope it never happens when I'm cleaning a really nice one.

I would say that a bottle which has no damage is unlikely to spontaneously exhibit new damage. Like Doug said, the bottles most likely already had some initial damage which could have been almost invisible. Early bottles often have very fine fractures from poor anealing. Once glass has a fracture, thermal stress can definately affect it.
