 Preserve
a snow crystal in resin and you can share it with friends and family in
the comfort of your living room – your very own personal snowflake
fossil.
I made the two examples you see on this page
using superglue, and you can easily try this yourself. You will need a
few inexpensive supplies:
1) A tube or two of
thin liquid superglue—not the gel type—which you can find at your local
drugstore or hardware store.
2) Some glass
microscope slides and cover slips, which are readily available online,
often both together in a box for less than $10.
3) A small paintbrush, the smaller the better.
4) A piece of dark cardboard or dark cloth.
|
|  Take all these items outside so they get cold, but away from falling
snow—for example in an unheated garage, a backyard shed, or just under
an eave. When snow is falling, let some crystals land on the cardboard
and have a look at what nature is providing. Use your magnifier for a
better view. When you see an outstanding crystal, gently pick it up
with the paintbrush (it’s easier than it sounds) and place it on a
clean glass slide. Carefully add a good-sized drop of cold superglue
right on top of the crystal, and place a cover slip on top of that.
You
may trap an air bubble or two along with your snow crystal; that's
okay. You can see some air bubbles in these two examples. |
| All this has to be done outside in the cold. You have to be careful
that heat from your hands doesn't melt the crystal, and even just
breathing on your snowflake can be detrimental. If you find that the
crystals are melting no matter what you do, then you may just have to
wait for a colder day. Handling snowflakes is generally easier in
colder conditions; it can be downright frustrating when the temperature
is just below freezing.
Finally, let the glue harden while it remains at sub-freezing
temperatures, which may take up to a week. If the weather is going to
stay cold, you can leave your slides outside in a sheltered spot. If
not, pop them in your kitchen freezer.
Once the glue hardens, the
slides can be brought to room temperature. Your fossilized snowflakes,
like insects trapped in amber, should last indefinitely. |
