I silver picked a beer bottle off of feebay and ended up having to return it to the seller. In the listing the description said "no chips or cracks". It arrived today and has a burst bubble on it. The seller is taking it back, but they said this is a "NATURAL BURST BUBBLE". What??? Never heard of such a thing. A bubble is natural to the old hand made glass manufacturing process, but I feel certain it was damaged to the bubble happened after it was tossed. What do you think?
