Silicosis is a real hazard…no question there…If you cast using
investment you are at risk when you open the container of investment
and every step of the way from mixing until the point when the flask
meets the water.Vapours and particles escape all but the most
state-of-the-art systems, generally not found in the small shop… I
posted about Rainbows for cleaning particulate matter a few months
ago… though not sure if it is appropriate to this thread, as i
haven’t read the entire thing yet. Fumes generated at the moment of
quench and the micro- particles that can be cleaned after settling
on surfaces,( unless you run the rainbow continuously while in the
studio which ordinarily, unless it’s been put into a noise reducing
chamber that is attached to the surface of the polishing area,
grinding area and just for air treatment due to the noise generated
-which is often the reason most people /companies do not run their
air treatment systems as they should be run in the first place,).
Rainbows are excellent machines, second to none for cleaning, air
treatment and a few other functions that rainbow SE systems
accomplish- way beyond any vacuum cleaner or ionizer or other air
treatment system on the market for smaller scale use…
They can be had far cheaper than the price Mary listed ( i have two
resources and if anyone wants to contact me off list about them,
I’ll share, or arrange for one for you - (i do not sell them nor make
gain for making the arrangements for one for anyone), however as
for silicosis, rainbows will not prevent you getting the disease if
you have been standing over the vat for years quenching flasks and
inhaling, without the appropriate respiratory protection on your
head…
Running the unit while doing many things in the studio though,
despite noise( which can be lessened easily), will help clear the
air, clean the air and if you like, enhance the ambient air quality
through the addition of various oil based simples and compounds that
do different things [for example, someone in the studio is sick
there’s a formula that is added to the basin of water to kill 99.9%
of the bacteria and airborne virus, and if your mood needs lifting -
and lemon, for instance, reminds you of a happy day selling lemonade
at your first stand, or grandma making it for you to quench your
thirst on vacation on a hot summer’s day, then the pure
non-synthetic oil of lemon can be added - will disperse with the
returned air and elevate your mood subconsciously, if not consciously
(in addition to the myriad properties of lemon oil itself), or if
you fancy Lavender oil , then add that ( I’m a vetiver & patchouli,
or juniper,oak moss,lemon and santal, orange& bay, or copal & vanilla
absolute &frank incense kind of person!)…and clean surfaces and
floors too]!Point is -any natural essential oil, or if you like the
company makes a number of fully synthetic scents and products that
can be added to the water in one of the various sized basins that
will make the air noticeably lighter, cleaner, and healthier- and
scented if so desired…
I have seen, recommended, and installed a number of large air
quality scrubbing systems in all manner of operations both industrial
and small scale- hands down the Rainbow is the way to go- If they
only made it in an industrial application size- and we could run it
on solar power and get the entire industrial world to turn it on in
sequence of the earth’s wind currents on one mutually agreeable day
(march 26th for instance!!!) day- I feel sure the planet’s health
would jump exponentially within that given 24 hour period…and if it
were quieter, and I were king of the universe, i would mandate that
every home and village install them and let em run, eliminating most
airborne junk relatively quickly from the planet, then run the water
leftover in the basins through various filters,reclaim the usable
stuff ( which, by the way metal particles are easily reclaimed from
the rainbow’s basins) and reuse the water for cultivating tress that
would contribute their own natural air cleaning and production to
assist the planet that is stressed way beyond its carrying capacity
as it is…
