Tried out melting aluminum cans for the first time today. 50 cans weigh about 600 grams. I am supposed to expect about 35% to be pure aluminum so I was hoping for around 210 grams in the end. I got only 109 grams and a ruined crucible clogged with solidified dross and leftover aluminum. I believe the problem was that I poured before the crucible and metal were hot enough with still too many impurities in the mix. I tried super heating the leftovers but they refused to melt. 83,89,53,0,B
