Yeah, I know putting in a new liquid would be bitchy, but seeing as how liquids can change stuff (magma first makes rocks into molten rocks), we could have a new, usable liquid.

Acid could strip living tissue to the bones. This could be used to dissolve corpses.

Dwarves disgusted by miasma? Throw the corpses into Acid!

Maybe it would be possible to make corpse rotting time longer, like a season or two.
Then there would be a nice practical use for it.

Defense could need it too. Acid could be easier to get than magma, and excellent against amphibious attackers.

Other than reactions, magma does the same thing, but then again, who doesn't want to use acid in dwarf fortress? The deaths might be slower... which is always better.

As a chemist this thread makes me facepalm so much.

Don't forget to take off your gloves.

If you were using the kind of acid liquid you get from mine drainage disasters, the goblins would say "Hey look!  This moat is a funny color!  And smells bad!  And now that I just swam to the other side, I kind of itch a little, and will probably not feel so good for a while.  But that's okay, because the dwarves sure aren't going to be fishing or drinking from wells round about EVER, and that makes them easier to siege..."

I don't think you're going to get enough concentrated acid to do anything meaningful without some AMAZING construction and engineering efforts.  Which is par for the course, sure.  But then you'd be tearing up half the mountain for a single tile of 7/7 acid, and it wouldn't even glow green or yellow or anything cool...

YES I know acids are complex. Some can disolve through metal but are safe to take a shower in. While some can't seem to disolve anything but will drill a hole right through you.

However, a basic acid system would be nice. If we want to match a more advanced one I guess we need to give the Acid specific materials it can affect and at what rate.

Though Id think the Acid should be capable of transmiting poisons as well. Since some poisons are acids.

I'm glad someone else caught that.  I was feeling exceptionally nerdy.

Also:  Vinegar is an acid.  So is basically any sort of citrus juice.  And aspirin.  PROBABLY you can't dissolve a corpse in them (well, it would take a loong time..) 

If you're talking something with enough "oomph" to dispose of a body, then you'd likely have trouble storing it in anything organic, in some kinds of rock (i.e. limestone) and in some kinds of metal (zinc goes fwooosh!).  I know that medieval alchemists WERE able to generate some pretty strong acids, so it should be doable in the DF tech level, but storing it might be problematic.

Sounds like you need some Hydrogen Fluoride (alien blood) or better yet Chlorine Trifluoride: a combustible highly reactive corrosive so heinous even the Nazis said "Hang on I don't think this is quite safe to put in our fiendishly designed self-igniting flamethrowers, guess we'll have to make do with normal flamers after all."

How about making acidity an aspect of the liquid in RAWs, I would make a liquid with:
[NAME:superacid]
[HOMOTHERM:-1000]
[ACIDITY:100]
[REACTION:REAGENTS:MATGLOSS_FLESH:1:PRODUCT:superacid:1]

It will freeze enemies then turn their flesh into more super acid!

Aw Jesus,  you just suggested "Witches Jelly".  http://www.cca.org/cm/picnic.pdf

Or possibly "gray goo", but I'm gonna go with Witches Jelly for the obscurity.

Wikipedia says:

Hydrochloric acid was first discovered around 800 AD by the alchemist Jabir ibn Hayyan (Geber), by mixing common salt with sulfuric acid ("vitriol").[1][2] Jabir discovered many important chemicals, and recorded his findings in over 20 books, which carried his chemical knowledge of hydrochloric acid and other basic chemicals for hundreds of years. Jabir's invention of the gold-dissolving aqua regia, consisting of hydrochloric acid and nitric acid, was of great interest to alchemists searching for the philosopher's stone.[1][2][3]

I think we can safely say that having alchemists make acid is well within the range of dwarf-tech. Just not in huge vats all at once.

Good thing we are talking about alchemy then:)

That just gives our chemist here more reasons to continue his physical abuse.

Goodness... I dislike when I accidently make puns that are also oxymorons like that.

It'd be nice if it existed, even if you couldn't make it. It would tie in well with the next version. Could probably make some manner of breath weapon out of it
