Today we will be testing a small furnace we made to melt Aluminium.
We will be making a larger version from a beer keg in the coming weeks and wanted to try a smaller version first as a proof of concept and test our design and materials.
We lined a regular steel bucket with fireplace insulating clay and cut a hole in the side to allow an air pipe to be inserted. The source of the air will be my wife's hair-dryer.
We want to test 3 things:
- How easy it is to reach temperatures of 700 degrees and will regular house coal and a hair-dryer reach those kind of temperatures?
- How well the insulating clay holds up to extreme temperatures and its reuse-ability.
- See if drinks cans are suitable as a source of aluminium and whether they will melt into something we can actually collect.
