[Nhcoll-l] glass jar with ground glass stopper

[Kathy Omura]

I have not worked with these types of jars and was wondering what to use on
the lids so they can be reopened. The jar will be holding a wet preserved
(70% EtOH) specimen.
I heard vaseline on the ground glass part of the lid and jar makes it
easier to reopen.
To make a tight seal, after the vaseline application, seal the lid with wax
along the edge.
What other options do I have? I appreciate any help you can provide.
