SNAP CRACKLE AND POP - 11/13/2007 6:19:11 PM    passthebottle   Posts: 255 Joined: 1/23/2007 Status: offline O.K. This is my second post on this subject, but just yesterday from my summer digs I choose 3 bottles to clean , a Horlicks Malted Milk ,a large utility and a local medicine. As I was soaking them after a good scrub in luke warm water I hear a snap, and as I feared 2of the bottles had cracked around the base almost perfectly and after sitting a little while the large utility bottles crack spread from the base to halfway up the side, and the Horlicks had cracked around the base and I think with a little tap the bottom would fall right out., the med survived. Be careful with changes in temperature while cl;eaning! Post #: 1

I have found if I let them sit in the house usually overnight the crack rate seems to go down. But on the same note I have found that bottles found from the 1910-1920 period have a higher crack rate. I think the glass was somehow different once they started full ABM. I think there is not much we can do to avoid it because sometimes it's just pressure from the glass being removed from the ground. But never hotter than lukewarm is the idea water temp.  _____________________________ McDirt (in reply to passthebottle) Post #: 2

I have a suspicion that the bottles that break already had hair line fractures... (in reply to passthebottle) Post #: 3

RE: SNAP CRACKLE AND POP - 11/15/2007 6:40:31 PM    tigue710 Posts: 1646 Joined: 7/11/2007 From: connecticut Status: offline I tend to inspect the bottles with extreme prejudice before I bring them home, and quite a few I thought were fine when first dug end up having small fractures here or there.  Some I don't see until I get the dirt off at home, but anything I soak has already been, inspected before brought home, and again while cleaning in the sink.  Anything that has ever gone into the bucket has come out with no new damage.  I do only use hose water for the bucket though, that might make a difference.  If digging toc dumps there also is the burn factor.  Many of these dumps were burnt or had hot coal ash thrown in them, which cooked the whole dump.  A lot of bottles which were cooked have become fragile with hair line cracks that are very hard to see or even invisible until the bottle is exposed to the air or sharp temperature change, which makes the crack expand, and then we all know the rest!

I have also had this problem and notice its the dumps that it happens the most. I have also noticed that Coke and Nehi bottles are the most brittle. I have dug over 100 cokes and Nehi that have cracked after they came out of the ground.I had a Bengal blueing bottle one time and had it full of cleaner and came back the next day it was laying in two pieces on the table.
