A couple of caveats.....I would strenuously recommend against wrapping
chrysotile or any other mineral specimen in Gladwrap. Creating envelopes
with anoxic plastics that can be heat- or impulse-sealed works MUCH
bettre. In fact, doing this can also save you the step of trying to
consolidate the specimen if there is not a real need to do so. Creating
the barrier envelope is a pricess I have used for mercury vapor-emitting
cinnabar; it also works well for containing fibres. There are also
Mylar-backed films that can be used in the same way if visibility/viewing
of the specimen is not important. COnsolidating and wrapping the specimen
may change it more than you realize, or desire.
