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.
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
