- 1). Burn a car tire cautiously for approximately 10 minutes. Do this in a safe and spacious outdoor location.
- 2). Place a stand over the burning fire. A typical stand has four legs that are approximately 15 to 20 cm long, and is often complemented by a shield to keep wind from disturbing the fire in any way.
- 3). Place the drum on the stand over the burning fire for a brief 90 seconds to two minutes.
- 4). Remove the steel drum from the fire carefully to begin cooling process. If there is not paint on the steel drum, the metal will turn blue, then black, and finally gray. The metal surface of the drum should look dull once is it heated enough and can serve as an indication on when it should be removed from heat.
- 5). Cool the steel drum. Pour cold water over the entire surface of the steel drum. The cold water will both temper and cleanse the steel drum.
