<div>Hi Laura,</div>
<div><br>
</div>
<div>the 3 mm gap between the lid and the neck of the jar is not the problem, unless the stopper itself fits nicely into the joint and the contact surfaces / diameters of the neck-joint and the stopper fit (i.e. the stopper would not
wobble in the joint). Even then, you could use slightly more Alsirol to fit the stopper in the slightly wider opening, because the Alsirol - compared e.g. to Vaseline, is rather stable and would not start flowing down.</div>
<div><br>
</div>
<div>Silicon and other sealants like putty are hard to remove and not so easily "reversible". The contact surface of the joint should be long enough to make a good closure, an additional gasket is not required in my view.</div>
<div><br>
</div>
<div>Hope this helps,</div>
<div>with best wishes</div>
<div>Dirk<br>

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>
<div>Thanks,<br clear="all">
