Follow the instructions for the exact incense format and burner. For a stick, cone or coil, use a stable heat-resistant holder on a clear surface, ignite only as directed, extinguish any sustained flame, supervise the ember and keep it away from children, pets and combustible materials. Ventilate the area and stop if smoke causes discomfort. Use burning charcoal only outdoors in fully open air, away from doors, windows and vents; never use it inside a home, vehicle, tent or partly enclosed space. For an electric heater, confirm the device voltage, frequency and plug first: a plug adapter does not convert voltage, and a 220V-only device must not be connected directly to a U.S. 110–120V outlet. See our incense use and safety guide before heating chips or incense.
