Hello I got a big 15 liters aluminum pot with a lid for free. It is old and kinda black inside. I want some tips/advices on what I can do with it except cooking? It feels booring to just use it as a pot . Only time I could think of using it that way is in a far away future when coloring wool or tanning a hide. I'm thinking about sawing it into pieces and make some sort of folding firebox. Anyone got plans for one? Or can't the aluminum handle the heat? Its like 2 mm thick. Another use for the aluminum is for knife handle material but it is probably good for a huge amount of knifes...
