This series explains how to build an electric kiln/furnace/oven, which can be used to melt metals, fire ceramics, burn out casting moulds (and make marshmallows).

In part 1 we start by cutting an old almond oil drum into the bottom and top lid pieces. Then fire bricks are cut to the correct shape to form an octagon shape, and finally they're mounted in the oil drum.

The silicate insulation material is also known as; calcium silicate and bio silicate.
