This experiment uses a variable temperature soldering iron to estimate the autoignition temperature of materials. This is not a particularly good estimation due to the characteristics of the iron tip and the energy limitations of the soldering iron. The temperature is increased by 50F after each test. What temperature does the nitrocellulose ignite? {F} What temperature does the match head ignite? (F) What does this tell you about the hazards associated with different materials and how they need to be stored
