What is the effect of a thicker material on ignition temperature?

Thicker materials typically require a higher ignition temperature due to the greater mass and thermal inertia they possess. When the thickness of a material increases, it generally holds more heat within its volume, making it less susceptible to reaching the temperature needed for ignition when exposed to heat sources. The heat must be sufficiently conducted through the exterior layers of the material to reach the inner layers where ignition can occur. Therefore, the thicker the material, the more energy is needed to raise the entire structure to the point of ignition, resulting in an increased ignition temperature.

The impact of material type, in contrast, suggests variability influenced by specific properties like density, moisture content, and chemical composition, which might alter the behavior of different materials under heat exposure. However, the fundamental principle regarding thickness's role in determining ignition temperature remains consistent across various materials.
