This sure sounds like a powdered reduction of Aqua Regia - Combo of HCL
and Nitric acid that is somehow powdered (I think by using ammonia, but
not sure) which can then be mixed into water. Extremely dangerous stuff,
and produces phosgene gas.... It is used in VERY WEAK solution, with
voltage, to dissolve and plate gold and Platinum.... also a great
cleaning solution with probably 1/1000th of the strength that you
used...say no more. Obviously, anytime this stuff is used, you need
ventilation that roars. You are a very lucky person. I would go find
the idiot that sold you that and stop him before he kills someone.

Subject: Re: [meteorite-list] Stange Happenings in the Shop
Hello Adam and the list,
hydrochloric acid has been widely used to remove calcite from the
mineral
specimens. The smell of rotten eggs means usually hydrogen sulphide, so
I
suppose, you have had a quite heavy liquid to clean the mets. Well,
natural
product anyway, no doubt...;-
If the stuff has been a mixture of hydrochlorid acide and sulphuric
acid, you
have been lucky you didnīt hurt yourselves, huh. If you pour water /
alcohol
to this heavy acid, the reaction may be very violent. But the mixture
sure
etches irons...
take care,
pekka s
