Hello
I have made an astounding discovery regarding
the freedoms we enjoy in the West.
One of my hobbies is the precipitation of micro-
crystals and their observation under the objective
of a microscope using various forms of illumi-
nation.
For this purpose I have used NaCl, also known
as table salt when sold over the counter at food
markets. This form of NaCl however contains
various impurities, some on purpose, some from
inadequate purification. The resulting crystals
are interesting, but show lack of perfect sym-
metry.
I have therefore tried to purchase analytical
grade NaCl from Sigma-Aldrich and Baddley
Chemicals. I did not know that at Sigma-Aldrich
one must go thru a "screening process" on ac-
count of the hazards posed to national security
by chemicals, including NaCl. In the process
of being "screened" I learned that no sales must
be made to individuals, no matter how harm-
less a substance may be. Same for Baddley
Chemicals.
How can it be, that the sale of NaCl and pre-
sumably of other, similarly harmless compounds
to individuals is forbidden? I can't imagine that
this is caused by true concern for the security of
a nation which prides itself for being the sole re-
maining superpower. Could it be that this regu-
lation serves the purpose of bringing all of sciene
under total federal control? Could it be that
the lack of science education among politicians
and lawmakers has led to such an excess?
I would be interested in comments regarding
this subject.
Thank you
G.R.
Hi
As a UK hobbyist I've had very similar experiences with chemical
companies. I suspect it's probably easiest, admin wise, for them just
to ban the entire chemicals catalogue to a private user rather than
for them to make choices about the hazards of any particular one. I
did persuade one company to sell me some buffer solutions to calibrate
my ph and conductivity meter and that was it. eBay is quite a good
source of lab grade chemicals for micro crystal studies.
