If you want to have a special appearance on the stage, the Fire Crown is a good choice, they are pieces of art, hand made. The fire crowns are made of copper tubes and wires. The size is adjustable, you can bend the copper tubes and wires, so they fit it well on your head. The weight of a three-section crown is about 450 grams, and burns for about 5 minutes or so. Only use lamp oil, do not use white gas. Make sure you shake off excess fuel, and always wear a hat or black cotton beanie for hair cover, to be safe. Black welding hats are very good/cheap and can be purchased at any welding supply store.
Use lamp oil only.
Always shake out excess fuel before you light up.
Have adequate safety personnel and procedures in place before lighting.
