sorry..another Q

I have not seen any yet, but while collecting insulators, finding one with "junk" or debris that found it's way into the molds is quite desired and intriguing. Is this common in bottles?

Hi OP, Having debris(rocks ,slag ,bugs ,etc.) in the glass makes bottles more desirable also. A glass string from one side to the other, inside the bottle, Known as a swing,can increase the value also. I wouldn't exactly call it common.
