This clay oil diffuser is glazed in a wonderfully deep red and heavily carved around the base with cletic knotwork. The upper bowl is a solid deep red to match the lower portion. The lower portion contains a rounded arch to allow safe placement of a tealight and is punctuated at every knot crossing by small vent holes that allow heat and light to escape creating a beautiful pattern on any nearby surface. The upper bowl may have a small portion of scented oil placed within to be heated and vaporized by the candle flame. Alternatively the bowl can be filled with water and potpourri or herbs. Measures aprox. 4 1/2 " by 3"
