I've been getting my HCl from the local swimming pool supply store, as liquid pool acid. It's labeled Muriatic Acid, and the the ingredient list says 31.45% HCl. It will crank your snoot if you don't keep it at arms length when opened, or have a big fan behind you, or only open it inside a fume hood. (The strong chemical filter masks will prevent breathing the fumes, but they won't stop them from getting inside your safety glasses, goggles, or face shield. And they won't block nitric at all.)

Ace Hardware has roto drain cleaner & liquid fire drain cleaner.

Both of these are concentrated sulfuric acid. You can recognize then because the bottles are on the shelf in a sealed plastic bag.

Baume is basically a scale related to specific gravity that was (is?) used in certain industries. At one point, I had a set of Baume hydrometers. Here's a conversion chart.

Great! if you were using it in accordance with the labeling instructions. but i didnt see gold refining mentioned anywhere in the video. :lol: im not closed minded and if anyone can come up with a full list of ingredients and Lou or Harold says its ok, then i might give it a try.
