[Nhcoll-l] Effects of fluid preserved specimens on passive environmental systems

[Bethany Palumbo]

Hi all,

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?

Advice and experiences would be greatly appreciated!
