Catalytic lamps provide a warm glow in any room. The soft light is pleasing to the eye and creates a mood of romance. The oil used within the lamps is normally unscented. Scented oil is available on the market and possible to make by adding a few drops of essential oil to the mixture. Clear catalytic diffuser oil is made from isopropyl alcohol and distilled water. Make coloured oil by adding a few drops of food colouring.
