Electric Kiln for Metal Melting

Advantages

• Low cost - essentially the cost of a $10 kiln heating element, and balance for refractory material and steel for case and legs.

Howto

• Connect 2 heating elements by threading around a threaded rod - 3:30
• 1.5 meters long works for 250V - 3:40
• Resistance in his case - 33 Ohm when cold - 3:45
• Fire Bricks - 5:20. Note CEBs work well as fire bricks per results from Hydronic Stove, and results would probably improve if we used perlite. This would be a good product.
