The glass bottle chimney protects the bottle candle flame from extinguishment, and fits both pewter and ceramic Bottle Candle designs. The glass bottle chimney turns any wine or champagne bottle into an attractive and mood-setting candle. Combined with the bottle candle, it makes a great gift for anyone who enjoys a relaxing romantic ambiance. Simply fill the bottle with enough Lamp Oil to submerge the wick, insert the wick / ceramic candle followed the glass chimney, and light. A bottle filled 75% of the way with oil can provide up to a full twenty-four hour period of light.
