Uh... It's been a while since Latin class but that means "water of life" or "marine life". It's also a phrase used for Brandy. Do you need a drink?

Hi you might try "scienceLab.com" and see if they can help?

I got this thing wrong.
Aqua Regia is what I'm looking for. aka: aqua regis, aqua fortis
I know how to make the solution, but I would rather buy it pre`made.
Research can be so time consuming.

You may get a visit from the IRS or Ossama B.L (äk´we re´jee) [Lat.,royal water], corrosive, fuming yellow liquid prepared by mixing one volume of concentrated nitric acid with three to four volumes of concentrated hydrochloric acid. It was so named by the alchemists because it dissolves gold and platinum, the “royal” metals, which do not dissolve in nitric or hydrochloric acid alone. Its fumes and yellow color are caused by reaction of nitric acid, HNO 3 , with hydrogen chloride, HCl, to form nitrosyl chloride, NOCl, chlorine, Cl 2 , and water; both chlorine and nitrosyl chloride are yellow-colored and volatile. The nitrosyl chloride further decomposes to nitric oxide, NO, and chlorine. Nitric acid is a powerful oxidizing agent (see oxidation and reduction ), but the chemical equilibrium for its reaction with gold, Au, only permits formation of a tiny amount of Au +3 ion, so the amount of gold dissolved in pure nitric acid is undetectable. The presence of chloride ion, Cl , allows formation of the stable chloraurate complex ion , AuCl 4 . Because of the high concentration of chloride ion in aqua regia, the Au +3 is reacted almost as soon as it is formed, keeping its concentration low; this allows oxidation of more Au to Au +3 , and the gold is dissolved. The gold may also react directly with the free chlorine in aqua regia, since chlorine is a powerful oxidizing agent.

2 points here: What in the heck do you want this stuff for??? and If you do build it make sure you store it in a sturdy plastic container as it will dissolve glass if I remember my Chemistry right.

Well, Mario explained what it is, and what it does. This sh*t is some prety nasty stuff. Face shield, rubber gloves, respirator. In the old days the Assay office would use the liquid to "single" out the gold from quartz, rock, and other particulates. These alchemist combined hydrochloric & Nitric acids together, and use this liquid (aqua fortis) to liquify the "royal" metals. (gold and platinum)
During the process the gold ataches to free radicals, and becomes positively charged. Whats left? Essentially, gold chlorine.(AuCl)
These chemicals are dangerous, but most of the chemicals under the sink in the kitchen are just as bad. Lye, bleach, ammonia; even "Comet" has chlorine in it.
I found an Assay in Sparks, Navada, near Reno that has the fluid, and laboratory equipment.
"The only thing I don't like is that; Reno is so close to hell, you can see Sparks from there."
This is my first step. The traditional way of making gold mirror is using a water solution of gelatin; which is "floated" on the glass, and "loose" gold leaf is physically applied. The gelatin dries and the gold leaf becomes mirror.
The non-conventional way of making gold mirror is a chemical process; very much like "silvering" in which gold chloride(AuCl+4) is used. The method is also called, "Angel" gilding.
The formula is as follows:
Solution A: distilled water: 80 cc gold chlorine (50-51%): 3 g Solution B: distilled water: 80 cc sodium carbonate, cryst: 8 g Solution C: distilles water: 80 cc formaldehyde (40%): 4 cc
For gilding, equal parts of the three solutions are mixed and diluted with distilled water to a concentration depending on the method of application. If poured on a glass and allowed to stand for twenty minutes, the gold solution should have a metal concentration of about 0.2% that is of the same order of manitude as that of most silvering solutions. The temperature required is 25ºC, but can increase gradually to 30ºC
More so the method depends upon the proper preparation of the glass surface, the "tinning".
In order to understand the Angel gilding process, you must understand how regular mirror. The process requires the "tinning" of glass, so that silver & gold can be deposited. This can be done using stannous chloride.
When you first posted this, my initial thought was "Angel Gild". I'm interested. I have some projects right now that I want to Angel Gild. My chemicals are old and some need to be replaced.

Mr. Bustamate hi.. Here are a couple of address that Rick used. (Del Amo Chemicals) 310-532-9214 /535 West 152nd St. Gardena Calif 90248 Next Pacific Coast Chemicals 510-549-3535 Berleley, Ca. Good for Commercially available Chemicals Next Chem Lab 714-630-7902 they sell 48 to 50% Hydrofluoric. There is also a Gold mining supplier that I am trying to find. I got it but a lot of syuff has been in storage. Keep up the good work, YATA Boy. Posted by Robert Beverly (Member # 1907) on :
Richard Glad to see your take on this....keep going please!
