[TheForge] RE: [TheForge ]Hydrochloric acid

[Ron Childers]

Bruce,

I doubt hydrochloric will etch ss effectively. I think in ss & cs Damascus
the ss is essentially unaffected. Isn't it the about the same as muriatic
acid? Nitric is some nasty stuff. Dangerous; spatters terribly, will rust
every thing in the shop and a drop will go to the bone. Muriatic is much
safer and more forgiving of carelessness, incapacity or neglect. Many
terrorists are killed, blinded or maimed using acids in homemade explosives.

Oh, yeah.  I should have added that using aqua regia on stainless is
probably not necessary.  Hydrochloric alone should work.  

For carbon, that's another thing.  The nitric might be necessary.

And another caveat:  The waste from nitric acid remains dangerous. 
Remember that nitrates are used in explosives.  So you should be real
careful how you dispose of this stuff, or a waste container may explode
on you.  I've seen it happen.

You should have taken the "OT" off the subject line.  Some folks use
that to fillter out the BS.

See http://en.wikipedia.org/wiki/Aqua_regia for info on aqua regia.

In principle, you could mix muriatic acid with sodium nitrate to get
aqua regia.  I haven't tried this, so don't know whether it would work
in practice.  

Be VERY careful handling strong acids.  We all know to add acid to
water, not water to acid, because the heat developed can bump (boil)
the
solution, and this is less likely and less dangerous if the solution
is
principally water.  What do you do when mixing two acids?  DO IT VERY
SLOWLY AND CAREFULLY.  Wear goggles AND a full face shield, protective
clothing AND a plastic apron (belt and suspenders).

Not to hijack this thread but I need some Nitric Acid.
I know there's a place in Miami (I live in West Palm
Beach and am too cheap to pay the high shipping) that
sells to schools but Google can't help find it. 

I want the Nitric Acid to make 'Aqua Regia' to engrave
my knives. A teacher gave me a small amount at the end
of the school year last year. It works great for
engraving my signature on carbon or stainless. 

I made a resist using bees wax and Asphultium
(apparently an old paint additive), sign with a blunt
brass rod, a few drops made for a great signature. 

I've been working with a sculptor and when I used it
for him the acid had lost it's power. Sorry for the
rambling post but I thought you would like to know why
I want the nitric.

I'm also going to Atlanta next week so if you know of
a supplier in that area let me know.

Thanks for your help,
Lynn
