what did they use before rubber rings, plastics
or rubber lined edges of metal lids?

pine resin/pitch? honey? wax seems too
hard and brittle. hmm...

i'm trying to make my list of things to have
on hand or know where to get easily just in case
we ever need them.

to replace metal lids i was thinking circles
of glass would work, with the edge ground to dull
the sharpness.

plastics don't appeal to me at all, but natural
latex or waxes would be ok as long as i can grow
them or somehow have a decent supply. plant based
products a definite plus, plant based products i
can actually grow here in the midwest USoA would
be even better.

right now i'm leaning towards a plant wax as i
think you only need a very thin layer to seal the
rims imperfections, but it would need some kind
of heat stablizer to protect it while sealing
(otherwise it would be a return to hot pack
methods and very little additional heat to seal).

any other ideas?
