RE: Preservative

From:"Monson, Frederick C."

Hi Carol,

I have always used 70% ethanol that is 10-20% glycerol to help retard
evaporation.  [Of course, you muscle people might not like all that glycerol
around, so you might substitute some isopropanol and/or some tertiary
butanol.]  Then I put on a screw cap over a layer of Parafilm@, trim off the
excess and invert the cap in my paraffin bath to give a good seal.  I have
not been as happy as a lark about the paraffin over the long haul, so, in
your place I might use some melted beeswax from a lit candle while I rotated
the jar underneath to get the melt in the cap-to-jar space.  Using a hot air
blower with a small orifice, you might get an even better seal - if you
don't want to open the thing for the next 20 years or so.

Hope this helps, even though its Friday and Germany won [BUT NOT by a rout.
Just by their usual style and quality of play.  USA in when?  2010 or 2014?
We may be much better, but can anyone be faster than those Brazilians?  And
can I live/hold on that long?]

Have a good weekend all,

Fred Monson
