I'm not so sure those disks are made of rubber (and judging from Candace's
original post, neither is she ... lotsa room between dried-out rubber and
ceramic) ... especially the one on the left seems to show deteriorated
ligneous fibers ...
... also, one of the things missing from all the published
accounts/discussions/webpages is the EVOLUTION in the invention &
development of the "ligneous disk" or "pog" type closure (mid-1880s to circa
1910... into the standard "paper" or "cardboard" one of later years > 1910)
... there were several different types of materials tried/used before
settling on the standardized wax-impregnated paper/cardboard insert (that
were still around during the childhoods of several subscribers on this
list)... and your illustration (p3 - Fig 6) appears to be of the later
cardboard type.
Candace's dates puts this artifact in the early range of the milk bottle
caps, so the ones from that era are not gonna look like the prettily printed
"paper" and "cardboard" versions, which are the ONLY ones apparently found
illustrated anywhere. I've actually seen examples of (very badly
deteriorated) rubber gaskets used under the bail-type metal milk bottle
closures, but none looked anything like Candaces' artifacts. HOWEVER, I have
seen (in junk shops, and private bottle collections, but not any museum
collections I can remember) examples of what I construed as gaskets in the
same context, that appeared to be rather similar to Candace's artifacts.
Anybody got a list of historic dairies (or bottlers ? might not be milk, but
still could be a bottle closure gasket ... someone suggested ink ... and
I've seen a LOT of ink bottles that came from school privies) in LA during
that period? Any "M & Ms" or "HQs" ?
