Backflow incense flows down through a backflow burner and creates a mist around the product.  This item must be placed on a heatproof surface.  When backflow incense burns the mist it creates can leave a light residue on the burner and the surface the burner is placed on, this is from natural oils and resins within the incense and can be wiped clean with a damp cloth.  Never leave burning incense unattended.  Comes with a small foam mat that the burner can be placed on when in use, however this is not heat proof so as stated above, the burner must be placed on a heatproof surface before using.
