Abstract
An oil lamp emitting a fragrance has a container including a fuel oil and a fragrance and a wick for drawing fuel oil out of the container for burning. A separate ceramic diffuser is positioned adjacent the top of the lamp, near the combustion end of the wick. The ceramic diffuser receives a combination of fuel oil and fragrance and diffuses the fragrance into the air. The diffusion is increased when the lamp is lighted. The lamp provides a scent to the surrounding air which is similar in strength to fragranced wax candles.
