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.

There's been a lot of previous threads about glass being in flux and not really a solid or a liquid. I've had too many bottles develop cracks after overnight or a few days later that appeared mint when first cleaned. Also, like Chris said some defects don't show up until the bottle dries for a while. A lot of the time this has been my own fault for not letting them sit or soak before washing them up, putting too much stress in the necks when cleaning, exposing them to the sun, etc. Not just temperature is at play here but think for over a hundred years that bottle had been held suspended in the ground under force. Changes in humidity, temperature and pressure are very gradual until being plucked from the earth, wall cavity or whatever. Add up all these dramatic changes, including solar exposure and trouble can happen.

Thanks for the replies.I can say for certain that three of these are bottles I bought, and did not have any damage prior to displaying them.I feel by keeping them up high along with the changes in temp and humidity is causing this to happen.It`s upsetting because I didn`t hit or bang them.Thanks again, Tom

WE HAVE THE OLD GAS HEATERS ,NO CENTRAL HEATING OR AIR. TEMPS NEVER THE SAME. I HAD A MINT WARNERS TIPPICANOE SETTING IN THE WINDOW [BAD IDEA ,LIKE LOBBET SAID.,I KEEP VERY CHEAP BOTTLES IN THE WINDOW NOW 75CENTS AND ONES I BROUGHT HOME FROM THE DUMP ,NO BODY ELSE WANTED] I TOOK IT DOWN TO CLEAN IT AND THERE WAS A CRACK RUNNING ALL THE WAY FROM THE NECK TO THE BOTTOM OF THE BOTTLE![:-] SOMETHING I COULD NOT HAVE MISSED WHEN I BOUGHT IT! OF COURSE I TURNED A SUSPICIOUS EYE ON MY LOVED ONE! [NEVER ASSUME!] SHE LET ME KNOW IN NO UNCERTAIN TERMS WASN'T HER. I FELT SICK ABOUT MY BOTTLE [LITTLE BAD BOUT THINKING IT WAS NINA] I GAVE IT AWAY CAUSE I COULDN'T STAND LOOKING AT IT! [WISH I HADN'T NOW!] SO I FEEL BAD FOR YOU![:@] IT IS A TERRIBLE FEELING I KNOW! AND MORE THEN ONE!![&o] JAMIE

I remember last winter, enjoying a nice toasty warm fire in the wood stove, and hearing a "ping" from the general direction of my bottles... I knew somebody just cracked, but couldn't figure out who, until I packed them for moving.. it was a bottle that had the slightest little crack, about 1/4 inch long, for 13 years since I dug it up.. I also recently cleaned close to 400 bottles, and cleaned about 300 without incident, until suddenly 4 in a row cracked as I was cleaning them.. I couldn't figure out what had changed, so I just tried another one, everything was OK, and finished the rest, again without any damage.. that spooked me a bit, still don't know why that happened..

There's one soda bottle that we find around there that often comes out looking fine - put it in the keeper pile, then, when we're ready to go, it always had fisheyes on it somewhere. I wonder if it has anything to do with the type of glass sometimes as well. It's only the Bethlehem Ribbon Cokes that always seem to do this.

If digging deep in winter, when finding a keeper, I would suggest at least wrapping it in newspaper before sending it to the top, so that the cold air doesn't pop it.

HEY KATE, IT DOES HAVE TO DO WITH THE GLASS, THE ORANGE CRUSH BOTTLES WERE ALWAYS WASTED IN MY TOLEDO DUMP, I THINK THE BURNING MAKES UM PING!

I have had some glass brake from cleaning it. I had a nice Indian milk bottle that got tapped just right with a bottle brush and put a hole in the base. I had just finished cleaning a mason jar, took my hand away and watched and heard it crack before my eyes. I had just cleaned an art glass vase with a 2" thick base. Four minutes later I hear a crack and notice glass dust around the base. I picked the vase up and it was in two pieces. I had a demijohn that I barely cleaned the out side. I came back the next day and it was all cracked.

Glass can do some very strange things.
