@boomzilla Now that's scary stuff. Nitric is nasty nasty, and glacial? Keep that very far away from me. In a locked safe in a locked bunker underground, with a 10' wall of cement. <shivers>

Ah, I guess you prefer fuming nitric acid?

I still remember in second-semester General Chem, we were dissolving a metal sample in boiling HNO3 in order to do a qualitative analysis on it. The acid spattered, and a couple of tiny drops landed on my hand. No real damage, but I had a couple of little yellow bumps for a while.
I don't remember whether, as a student lab tech, I ever had to make working-strength HNO3 solutions from the bottles of concentrated. I do remember making H2SO4 and NaOH, and probably HCl, but I don't remember whether I ever had to dilute HNO3. Again, too many s under the bridge.
I have a small bottle of HNO3 in my workshop right now. Not concentrated, though. It's a commercial metal-etching solution, so I assume it's fairly dilute. At a guess, maybe 10% or less. The MSDS might tell me, but . Even so, the hazmat shipping cost more than the product, I think.

To make the mockery of the rest you snipped more obvious.

Sulphuric acid, ammonia and hydrochloric acid are relatively benign by comparison with nitric acid. It's the “oxidising agent” warning on the bottle that should scare you a lot; that's a big part of the real recipe for uncontained fun.

Meh, I once threw a coin into concentrated HNO3 and had to cover the glass with hand* Ended up with only yellow discoloration, no burns. It simply doesn't penetrate tissues that much. The really dangerous stuff is bases (including concentrated ammonia), which basically turn you into soap, and hydrofluoric acid. HF is probably the worst, because it poisons you internally, even though it's a weak acid and you don't feel any burning sensation before you collapse and die from heart failure.
*because the teacher came back.

It depends very much on what you cover up with. It's an oxidising agent, so it strongly encourages other things to burn, but those other materials are very much variable in how much they'll burn. People don't burn too well; they're too wet, and the skin is pretty resistant to a lot of things due to having a lot of complicated fat cell membrane layers. Other things you might have covered up with could have been a lot more exciting. (In general, it's one to be careful with because if you're splashing it around you don't know what it's going to be coming into contact with.)
As you say, bases are tricky because they react with fats. (OTOH, if you get on with it you can just wash them off.) And HF is *special*! It reacts with all sorts of things that are common in labs, such as glassware and such. Another one to really avoid is liquid bromine, again because it does a nasty number on your body chemistry; I've heard of that killing people. The safety guidelines in the material datasheet are there for your protection.

Oh, absolutely. You can make nitrocellulose with it, after all. Although this still requires a mixture of concentrated HNO3 and H2SO4 and high temp. And when boiled with alcohol and other 'readily oxidizable' things like that, it will explode. But it's simply slow at dissolving humans. It denaturates proteins very quickly, doesn't do much to fatty acids, and because fats and denaturated proteins are water-insoluble, they slow down further damage.
And HF is special! It reacts with all sorts of things that are common in labs, such as glassware and such.
Not only that. It's a weak acid (weaker than vinegar), but it has small molecules which will quickly migrate deep into soft tissues, until they meet calcium atoms, because CaF2 is almost insoluble. So once HF enters your body, it will remove calcium from blood until your nervous system fails and you drop dead. Of course it will also cause cell death by other means, but that is what kills you.

@boomzilla this also could go in the D&D thread. It perfectly describes players' SOP 99% of the time.

After leaving the first two towns in ruins (and being well on our way to a third), our ostensibly good party ended the campaign by joining forces with the Big Bad (or at least the rogue did).
