collection. </span><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 14.6667px; color: rgb(0, 0, 0); background-color: rgb(255, 255, 255);">We have successfully sealed these jars with silicon
caulk in the past, but certain of its curing products - such as acetic acid - could affect the fluid.

if you thinly coat both glass faces with non-setting vacuum grease. If you do use caulk, use very little pressure on the clamp as without a gasket you could crack the lid through overtightening or even temperature changes. </span></div>

<div dir="ltr">Hello everybody,
<div><br>
</div>
<div>I've been reading some thread emails about sealants in historic jars, but I can't find what the best way to close these jars is (see photos attached). I was planning to get Alsirol, but then I realized that there is a 3 mm. space between the rim and lid.
The "best" will be a gasket, but I'm not sure if there are proper gaskets for these jars.</div>
<div><br>
</div>
<div>I would appreciate your recommendations or advice.</div>
<div><br>
</div>
<div>Thanks,<br clear="all">
