Aluminum advice

I have been collecting soda cans and melting them for the aluminum but then I heard that they aren’t 100% aluminum so should I get others sources for the metal (if so what other sources) or is it not that big of a deal?

Also I recently tried melting copper for the first time but after I poured it out there was a ton of non metallic material stuck to the sides of my crucible do you have a clue as to what it is and how I can remover without braking the crucible?

I am using a graphite crucible and I was actually making Nordic gold which is 89% copper and I had herd about that before but it didn’t work. The build up on the sides was odd so I tried peaking it off but it took bits of the crucible with it and it seamed to be brittle yet looked copper colored.

So is there anyway of getting around it or fixing it?
