"Working with fire is like working with a strange alien force that you bring to life and try to choreograph, says Hartz. "However, at the right time, you have to make sure you know how to make it die and go away.”
Hartz, who fell in love with fire as a Boy Scout, earned his pyrotechnics license in Canada and over the years has competed internationally in the art of fire sculpting. He won first place in 2000 at the Pacific Northwest Fire Sculpture Championship in Seattle. He also helped found the Cirque De Flambe in Seattle and has crafted fire logos for festivals and organizations, including Fox TV.
Typical fire sculptures are made of materials such as wood, thatch and string. The more elaborate pieces can include motion and are usually judgded based upon the appearance of the structure before, during and after the burn.
