crystalium oxide: a white highly unstable material found within opal clusters, can ignite and blow up even from the heat from smelters. very light and sharp.

Great story--sounds like a Fun mod! I'm a little confused though. If it blows up when heated, how can it be forged into weapons?

(Trying to figure how to make the chemistry work in the spoiler:)

Shouldn't Crystalium Oxide be inert? Pure Crystalium could be volatile as hell, but the oxide itself would be the product of combustion. (Note that it would be accurate to find Crystalium Oxide rather than the pure element. Such a volatile chemical is extremely unlikely to be found in a pure state.) Unless... Could the explosion be a reducing reaction that runs off moisture in the air? Are there any chemists in the audience that could answer this question? It's been way too long since I studied this stuff.

Hmm. Trying to make the chemistry of a Rule of Cool mod follow Real Life rules probably counts as a face palm-worthy moment.

it isnt supposted to be based of real life crystalium, infact i didnt even knew that there is such thing.
also im trying to mod crystalium to explode into shards instead, and i think it could be smelted if i would add freezium into the recipe.

freezium: a valuable cyan material. due to his low fixed temp, it is VERY useful preventing fires and magma accidents.

Nether-caps, found in the bottom cavern layer, produce wood that is always 0ºC

Well.  This thread seems to have averted a facepalm moment then.  Play my custom race in which some castes have a very low cold tolerance (0 degrees is fatal).  It would have been a terrible thing to place a number of beds made of that wood in the dorms...

The funny part would be how long it would take me to figure out why seemingly random members of the fortress suddenly keep dropping dead in the dorms.

I did not know that!
wow.

Reduction of oxides rarely occurs without a strong reducing agent ie not often in nature. Oxygen (which is a good oxidising agent, funnily enough) is too abundant for that.

No no, it doesn't actually exist. I was just trying to figure out how it would work if it was real. Which was pretty futile in the end. Hence the "this probably counts as a face-palm moment" remark at the end of the post.

there is a megabeast in my local cave and i lost 5 of my 7 starting dwarfs to it

its ok now i locked it up and i am sending in useless migrants for him to snack on

I actually equip arena mode creatures in it. It allows me to survive a magma swim for about twice as long.

No because an oxide isn't the product of combustion, it's the product of oxidization.  Iron Oxide (rust) happens because the metal is exposed to air.  Presumably the pure Crystalium (yeah I know it isn't real) would end up having a thin coat of oxide to protect it from further corrosion as it'd be a reactive metal, but it'd presumably be only chemically, and not physically, reactive in its pure state.  Reactive metals form bonds more easily (and most often with oxygen) to maintain stability.  The oxygen that bonds to it would make it more volatile, as oxygen is a key part of combustion, as can be see with the awesome reaction of Fe2O3+Al+Heat=More Heat+Fe, more commonly referred to as Thermite.

Yes I know, every time you inject science into a fantasy discussion God kills a catgirl, but it just bugged me.  And actually I'm a Biologist so

And you were doing so well, too...

("Volatile" in chemical terms is "easy to evaporate". This happens to contribute to the explosion risk of flammables, as flammable volatiles like gasoline can pre-mix with air, but "volatile" does not mean "combustible". It refers to the ease of changing state, and that has led to the more general usage of a situation that is prone to rapidly changing - and unfortunately, is often associated with blowing up. This connotation is creeping back into use in a chemical context, erroneously.)

I do apologize, sometimes the layman in me gets the better of me.

You missed some of the Products and didn't balance the equation. 3 FeO₂ + 2 Al + Heat = 3 Fe + 2 Al₂O₃ + Way more Heat
Chem 20 FTW!   Sorry 'bout that but my Chem teacher drilled this into my head and chemical equations have to look like this.

[Shurhaian]

If we're going to be technical, I don't think the energy involved - especially not the activation energy - is normally listed in a chemical reaction on either the reagents OR the products side.

[Geti]

Yeah and it's expressed as an enthalpy change and then-
Oh wait we're careening off topic and the technicalities behind writing an equation rarely actually matter when you're using it for explanation's sake.

Heh, I always get "Urist McWrestler cancels spar: seeking infant".  I can just imagine dwarven babies flying through the air after a particularly rough takedown....
