What does small crazing of glass typically indicate?

• A. Slow and steady heat
• B. Intense and rapid heat build up
• C. Consistent fire behavior
• D. Normal household conditions

Answer: (B)

Small crazing of glass typically indicates intense and rapid heat build-up. This phenomenon occurs when glass is subjected to high temperatures quickly, causing the surface to expand and contract. The stresses from sudden temperature changes result in small cracks or crazing patterns in the glass. In the context of fire investigation, recognizing small crazing patterns helps investigators determine the heat exposure and intensity during a fire incident. When analyzing glass as part of a fire scene examination, the presence of crazing can indicate that a rapid and fierce heat source was present, potentially suggesting the use of accelerants or intense flames. Understanding this characteristic helps fire investigators piece together the events leading up to a fire, affirming the hypothesis regarding the fire's intensity and behavior.
