[Comments] (8) Metal Fire!: Sorry, but it's my Constitutional right to shout "Fire!" in a crowded weblog. And what cooler kind of fire to shout than metal fire? Magnesium, uranium, aluminum... they'll all go up in flames. Don't even get me started on nature's deathtrap, sodium.

I guess I knew about metal combustion before, because I'd seen the pretty spectrographic colors metal dust makes when thrown into a fire. And it's not surprising that for metals with nearly-empty outer electron shells, a fine line would divide oxidation from combustion. But never before had I envisioned metals catching fire on their own and wreaking havoc, or conceived of high-tech fires deemed worthy of their own fire class (D) and requiring special fire extinguishers to appease. Even though your aluminum foil isn't going to catch on fire, the idea has a certain cutting-edge cyberpunk allure.

Personally, I always liked potassium... it 'splodes like sodium... but even moreso, if I remember correctly.

Makes sense, since it's right under sodium in the periodic table. Cesium and rubidium would be even worse.

what's also fun about those metals (at least sodium and potassium) is that they are very soft -- you can cut them with a scalpel.

incendiary bombs often contain both aluminum and iron powder.

...maybe i've said too much.

Thermite! Aluminum and iron oxide in 1:1 molar ratio. Ignite with magnesium fuse.

...and what do you get?

METAL FIRE!!!!

Metalfire should have been the name of an 80s Christian metal band.
