A candle snuffer is a tool used to extinguish candles safely and efficiently. It typically consists of a small bell-shaped or cone-shaped metal cup attached to a handle. To use a candle snuffer, you place the cup over the flame of the candle, cutting off the oxygen supply and causing the flame to go out. This method helps prevent hot wax from splattering and reduces the risk of accidentally blowing wax or sparks onto nearby surfaces, thus reducing the risk of fire hazards. Candle snuffers are commonly used in households, religious ceremonies, and formal events.
