Boiling metals Copper and Aluminum
I tried to heat these metals in an electric arc to boil them.
And it succeeded ....

It is not an good idee to boil metal , you can catch the metal fume fever.
I never asked for this.

Normally it is zinc which gives you fume fever. Copper gives you a case of coughing, hacking, sore throat and death. To be honest I can't recall what
boiling Al does to your lungs, other then it would be likely be Al2O3 by the time it made it to you, a nuance dust IIRC.
In ether case we hope your wearing the correct protection yadda yadda.
I'm missing the point of your latest posts, where's the mustard? er science? Or are you just experimenting to see what does what? Are you playing with
boiling point depression or alloys?

Hmmm... these metals should condense quite quickly in the cold, surrounding air, subjecting the experimenter possibly to fine oxidised metal powder,
not to metal vapour. Zinc has the lowest BP though... A good quality dustmask is the least kind of protection needed, at a minimum, in all cases.

True, though the copper stays metallic for a while. CuO/Al will nicely Cu plate; grass, twigs, the inside of your lungs, acorns, plastics etc.
The copper is a toxic heavy metal irritant
Zinc oxide triggers a massive immune response (some times) - the fume fever is the result.

Al boil at 2740 K ....impressive ...although an arc welder can reach 10 000 F a TIG can get it up to 35 000 F ! Al is easy target..try tungsten at
5930 K !! have fun!
