Abstract: A water buffered essential oil non-open flame incensing system including a level fire plate with a metallic fire ring centrally bonded to the upper surface thereof. A stoneware urn is provided having a body portion with a pronounced belly, a bell lip, a throat defined between the body portion and the bell lip, a curved interior surface with a non-flat bottom portion, and an exterior surface. At least the curved interior surface has high fire glazed finish. Water and essential oils to be diffused are filled in the urn and the urn is placed on top of a burning charcoal briquette on the fire ring. Boiling of the water carries the oil in the form of droplets into the atmosphere. The urn is sized to have a small amount of water left at the time the charcoal burns out. A smokeless system may be beneficial for people with smoke allergies.
