A stunningly simple black ceramic backflow incense burner in a pool to pool design.When the cone is lit the smoke from the cone pours downwards into the small pool then cascades in to the larger pool in a mesmerising waterfall effect. Beautiful to watch.For best effects burn indoors in an area away from any sudden air movements. Please note that after burning it is normal for a light oily residue to appear on the oil burner, for this reason we recommend protecting any furniture it is placed upon suitably. The residue can be easily wiped off the burner with a damp cloth. Please exercise caution when burning incense. Only backflow incense cones should be used with this product – standard incense cones will not create the desired effect. It is normal for cones to take up to 10 minutes after being lit to start creating the smoking/mist effect. We supply a selection of backflow incense cones in a variety of scents.
