<div class="moz-cite-prefix">... brushing with a brass brush works
very well, too; this method has the advantage that you bring the
very thin silicone film off that normally remains on the glass
surface (e.g. if you use razor blades to scratch the silicone off
- old aquarium hobbyist trick ;-)<br>
<br>
A bit tiresome so, but good results (may stain the glass surface a
bit golden, but this rather just looks fancy without causing
trouble). For closing again, use a high quality vacuum grease (be
sure to exclude any silicone based vacuum greases). <br>

is right, don't try to pry the lid off silicon. Once the lid
has been removed, you can scrape the silicon off with a blade,
then use a silicon release agent (which you can buy at a
hardware store) to get the remaining silicon off of the glass
before you apply a new gasket.<br>

looks as though your lids have been glued on with clear
silicone caulk. This can stick to old glass like crazy
and makes getting the lid off tricky. Rather than trying
to dissolve it or pull the lid off, my recommendation
would be to cut through the silicone all round with a
fine model-makers's saw or an X-acto knife with a long
blade.

have several old glass containers housing
fish, herps, inverts, etc. that are
getting very low on fluid. I expect the
containers are pretty brittle, as a gar
with a giant lobster broke with almost no
provocation and spewed formalin all over:
not a process I want to repeat. I don't
have any idea what these specimens are
stored in.</div>
