So we have sodium and mercury lamps. Which heat up a vaporize said metals to form plasma arcs.
What is stopping us from upping the heat and vaporizing say... copper, iron, tin, maybe even uranium, gold, lead, Into a plasma arc?
What colors would be produced by such vaporized metals?
I am sure there is alot of fundamental knowledge I am missing. But from my understanding with a thick enough quartz wall and large enough electrodes or electromagnet, it maybe possible to vaporize anything into a plasma state for atleast a short while yes?
I am assuming this has been done somewhere. But I am having trouble finding examples on the web. And finding pictures of said discharges is hard because alot of the search engines also pull up pictures from movies/news articles/market listings for unrelated stuff.
