<p class="MsoNormal">I’m not a conservator, but since the ethanol would evaporate before the water, the risk of high humidity seems less than the fear of fire. And even that, you’d probably need to fill the entire display case with ETOH vapor, which may be
far more than could come from the jar(s) on display, for that to be possible. And I’d think that empty jars would be noticed long before things went “boom”.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">On the other hand, you might worry that the reduced humidity would interfere with the ability of the closure on the jar to seal properly. But that can be worked around, if it’s an issue. A little aquarium sealant could help resolve that.<o:p></o:p></p>

<p class="MsoNormal">Hi all,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I would like to know if anyone has experienced adverse effects on passive environmental systems from fluid preserved specimens displayed in 70% ethanol. Imagine the scenario that a display case has both fluid-preserved specimens in glass
jars and taxidermy in the same case. I would want to add silica gel in the showcase to maintain a stable humidity for the taxidermy, but would the (30%) water content in the jars affect this? Obviously the quality of the sealant on the jar affects any evaporation
rate, but how sealed is sealed enough? Does anyone know of any research in this specific issue?<o:p></o:p></p>

<p class="MsoNormal">Advice and experiences would be greatly appreciated!<o:p></o:p></p>
