Mike,

The company '3M' (Scotch) make a water clear plastic film that shrinks
when heated, it is used to draught proof windows (the glass type!) the
idea being you tape the sheet over a pane of glass and heat it with a
hair dryer and it shrinks tight like glass

I tried some once, and it works very well, don't ask me where you get
it, I got mine ages ago, but maybe a hardware store would be the place
to start.

Actually food wrap does shrink slightly when warmed so maybe that's
another way of getting a good snug fit, then you would be able to see
the specimen under magnification without the wrinkles of the plastic
film getting in the way.

Cheers,

Mark Ford

Hello List,
What I am about to suggest does not have all of the positive attributes
of a true HQ membrane case, such as the one offered by Ron Hartman and
in no way should it be considered an equal substitute.

This idea is for those, like me, that are in need of temporary
protection (from the likes of the dreaded Count Vac-u-lar !) for our
precious micromounts and fragments.

To enjoy viewing a specimen without removing it from the case, obtain a
crystal clear acrylic1x1or 2x2 box. Gently stretch an over size piece of
plastic food wrap across the bottom half of the case. Hold the wrap
taunt and position the specimen. Align and press on the lid. The plastic
wrap should stretch and pull the specimen tightly to the inside of the
lid. Use a sharp to cut away the excess wrap. That's it !

I hope someone will find this helpful.

Best wishes to all,
Mike Gallant IMCA 7583
