What is a glowing splint?

A glowing splint is a small piece of wood or paper that has been ignited and is still smoldering. It emits a faint red or orange glow due to the heat produced by the combustion process. When brought near a gas, the gas will ignite and burn the splint, producing a flame. This is due to the high flammability of gases such as hydrogen, methane, and propane. Glowing splints are commonly used in chemistry experiments to detect the presence of gases and to identify their properties. They are also used in industrial settings to detect gas leaks and in fire safety training to demonstrate the dangers of gases.
