Dear All,
would pure Glycerine oil be a good preservative for empty (under 2mm)
microshells? Glycerine is water soluble.
Would modern synthetic oils have any long term chemical effects on shells, since
they seem to have a shelf life.
I tried silicon spray on some shells, but it seems to perish after a while.
