I have collected some beautiful specimens during the Gem-O-Rama, what should I do with them now?
All Specimens are Water Soluble
All the saline minerals you collect on Searles Dry Lake are soluble
in water. Therefore, do not wash them in water. Doing so will at
least etch the faces, and in the extreme, totally dissolve the
specimen.
We have heard stories of people leaving their specimens in a bucket of
water over night and then thinking that someone had stolen their
crystals
when they found them missing the next morning.
Washing Hanksite and
Sulfohalite.
Hanksite and Sulfohalite can be washed in Searles Lake brine without
etching the smooth faces of the crystals. But when you put them in
brine, wash them, don't just soak them. Washing can best be done using
a brush with medium-firm bristles to scrub mud from the crystal surface
and cracks where crystal faces meet. Don't soak your crystals for hours
in Searles Lake brine. Soaking crystals over night in Searles Lake
brine can damage the crystal faces because the solubility of the
crystals in the brine change as the brine temperature changes, and the
change is solubility can cause the crystal faces to be damaged.
Hanksite and Sulfohalite can Absorb Water from
the
Air
Hanksite and Sulfohalite will readily absorb water from the air when
the relative humidity of the air exceeds 65%. After you have
washed
your Hanksite and Sulfohalite specimens in brine, they must then be
completely
dried. Warm air is the best way to dry them. In Trona the
ambient
air is sufficiently dry to dry your specimens. In more humid
locations,
such as along the coast, a hair drier may be needed to dry your
specimens.
To best preserve your specimens after drying, the surface must be keep
dry and contact with humid air must be prevented. For Hanksite
and
Sulfohalite, you can immerse them in clear mineral oil and then wipe
off
the excess, but this may have to be repeated evey year or so to keep a
tight cover of oil. If your specimens become dusty, they can
simply
be reoiled. A clear acrylic spray may also be used on Hanksite
and
Sulfohalite but it may be difficult to achieve a thin yet 100%
coating.
If acrylic spray is used, it should be a non-yellowing type.
Sprayed
specimens can simply be dusted when this becomes necessary.
Care of Your Pink Halite Specimens
Three things are important to consider when caring for your pink Halite
specimens, they are light sensitive, they are somewhat fragile, and
they
can absorb water from very humid air (over about 75%). The
beautiful
pink color comes from the presence of halophylic bacteria and algae in
the salt. This means that the color is naturally occurring and
has
not been tailor made to be resistant to fading. Therefore, strong
light, especially sunlight and light from fluorescent bulbs will fairly
quickly cause the pink color to fade. Therefore, when you display
your specimens, put them into a low light area, well away from direct
sunlight.
Of course, this will not allow their beauty to be seen all the time,
but
there is nothing wrong with turning on a bright light whenever you want
to show them to friends. Just turn the bright light off when you
are done. (This is also good energy conservation.)
The fragility of the pink Halite comes from the fact that these specimens are agglomerates of crystals stuck together with dried salt as the glue. Since salt is quite soft, the glue is weak. What this means is that the pink Halite should be handled as little as possible. Ideally, you would put it into a glass-top display case that would remain stationary while your friends look at your specimen.
Although we have heard of people spraying their pink Halite with
clear
acrylic spray, we cannot at this time recommend it. Our
recommendation
is to use a sealed display case to show your pink Halite. If you
live in a humid climate, you may also want to add to your case a
package
of water absorbant such as those packaged with some electronics
equipment.
