Orchid is a metals thread, by and large. When I say to solder
something, I don't feel the need to say, "Don't point the torch at
your hand, don't drink your pickle." and the like, because that is
assumed. Chemistry, as in professional chemistry, is no different.
If you go anywhere online and research "Uranium Hexafluoride" you'll
find the process layed out: Get uranium cake, treat with HNO3, treat
with fluorine, etc. Pretty simple, except for getting the uranium to
begin with. What they don't tell you, because it's assumed, is that
this all occurs in a $25mill facility in the absence of human
beings, because your survival time upon entering the room would be
20 seconds, max. The point of all this is that you need to use your
brain. First off, don't post suicidal processes online to begin with
(bozo), and if you should read such things, think about
self-preservation first: "Wait a minute - maybe there's a reason the
chemical supply house won't sell me that?" The chemistry of jewelry
is fairly benign most of the time - flux, Sparex, ferric chloride,
some fairly hazardous plating solutions. But when you get into
photoetching, gold etching, plastics and other, more arcane things
you can easily kill yourself if you don't educate yourself first.
There are some here on Orchid who consider flux and Sparex to be
some hazardous, toxic stuff - well all chemicals deserve respect,
but borax is in laundry detergent, fercrissake. It's far better to
have that than to have people washing their windows with HF, though.
A little fear is better than foolishness, most of the time. Today
R.E. mentioned etching with hydrazine, with appropriate GIANT RED
FLAGS. 99% of the readers here are better off not ever being withing
100 yards of the stuff, and the other 1% knows just what to do with
it. Understand that there are chemical things that you may become
aware of that carry a great weight behind them, though what you read
might just say, "Do this, Mix that" and if you don't understand that
it could be very, very bad indeed.
