Q.Immediately after ignition and extinguishing, a metallic “popping” or “clanking” sound is heard.

Distortion occurs when the metal inside the product expands under the influence of heat from combustion. During extinguishing, distortion occurs when the expanded metal cools down and contracts, which may cause a noise.
