my question is, can i get more money for my cans and scrap aluminum if i melt them into large ingots, or am i just waisting my time? This crucible seems to work good i would just make it on a larger scale. You must be logged in to see this link.
And he that hath lyberte ought to kepe hit wel / For nothyng is better than lyberte / For lyberte shold not be wel sold for alle the gold and syluer of all the world. -Caxton's edition of Aesop's Fables, 1484
Making Al ingots just makes it easier to store, unless you're making a replacement part or toy soldiers to replicate you favorite historical scene. You got to factor in the cost of the heat to liquefy everything! Of course if you enjoy melting and pouring stuff, the enjoyment factor will offset (some of) the energy cost. I have gotten more ($.05/lb) for nice looking ingots than the squashed can price. I get the same as the can price for "puddles" left from melting cans in bonfires. I've thought about taking a brush on a drill and trying to clean up some of those "puddles" and selling them as art. They can look pretty neat sometimes.
Weigh ten pounds, melt, figuring the cost of heat and the time involved, weigh what is left and tell us how much difference you made and how much time it took. Wood fire is cheap for melting aluminum.
