Must've had a lot of copper in that asteroid.
31 0 ReplyProbably nickel and/or salts of barium. Copper burns blue as a pyrotechnic colorant.
21 0 ReplyAh ok. I was going to say nickel but I did a quick search and somehow I read that it was copper.
6 0 ReplyDepending on the salt you can make both blue and green. Copper sulphate flame test is a pretty common school lab practical isn't it?

A lot of spaceship debris looks like this because copper is used in a lot of rocket engines.
8 0 ReplyAlternatively or additionally, I think oxygen plasma glows blue or green, because northern lights (near the poles, at least) are greenish.
