[Nhcoll-l] [EXTERN] Re: Repairing historical glass lid

[Dirk Neumann]

... other wise you can just go the a glass workshop and ask the people there to cut you a new one. It would be good if the rim (approx. 1cm) would be ground to improve the attachment of the sealant on the glass surface of the lid.

With best wishes

Hi Katrina,

I always cut my own by hand and grind the edges too. If you cannot find an easy ready-made solution, I can send you a blurb of how to do this and some tried-and-tested sealant information  too.

With all good wishes, Simon

Hi All,

We have a historical glass jar storing a nemertine worm whose lid has cracked and is no longer forming a seal. Because the worm is prepared so uniquely and the jar is so tall (41.5 cm tall), the likelihood of finding a replacement is pretty low unless we invest in a custom made jar (which is unlikely since it’s a teaching specimen).

Does anyone know if there is a glue/epoxy that we could use to stabilize the cracks in the jar lid that won’t react with the ethanol preservative? Further, I’m not sure if there is a glue that won’t expand too much that it will further compromise the seal while we look for a more permanent solution.

Thank you for any insight you might have (picture of lid below).
