What type of material is referred to as "flame effect material"?

Flame effect material is specifically defined in the context of flame effects used before an audience as a flammable material that serves as fuel for creating the visual element of flames. This type of material is integral to generating the desired flame effects in theatrical productions, performances, and similar events, enabling artists and technicians to produce controlled flames that enhance the spectacle and ambiance.

The other options do not accurately describe flame effect material. Non-combustible materials, while essential for safety, do not produce flames themselves. Decorative materials may enhance the visual aspects of a performance but do not serve the functional purpose of generating flames. Lastly, a special type of fuel that does not produce flames would contradict the very definition of flame effect material, which relies on the ability to create visible flames. Thus, recognizing the role of flammable materials in flame effects is crucial for the safe and effective use of these effects in performances.
