the mess of machining cast iron

Gunner Asch fired this volley in : To be fair..it does need a good oxidizer to help as an accellerant. It needs LOTS of oxidizer. With gobs of barium nitrate (which is a good one), iron dust barely burns. THAT is what sparklers are made of. Cast iron dust doesn't become pyrophoric until it's down below 1/4- micron, and then only if it's deliberately cast into the air. Sucking the stuff up with a vacuum cleaner would be more likely to cause trouble than sweeping the stuff up. I've got a pile of cast iron dust I can experiment with now. |
