This homemade furnace and crucible contains molten aluminium. We made it with two clay flowerpots, a small air compressor, and a crucible made from a welding torch gas bottle. The compressor provides oxygen in the form of air to the base of the furnace, enabling a high rate of combustion.

This image shows aluminium being poured from the crucible into the concave surface on top of an ordinary house brick. We heated up the brick by resting it on the furnace to prevent the aluminium cooling too quickly on contact.

Several videos of this process are in the video gallery .
