Frosted oil lamp chimneys have a white frosted appearance on 3/4 of the chimney. Help reduce glare on electrified oil lamps with clear glass shades by using frosted oil lamp chimneys. Use low wattage standard bulbs with frosted oil lamp chimneys to reduce heat build up. Smaller shaped Torpedo or Candle shaped light bulbs work well with glass chimneys. Frosted oil lamp chimneys fit #2 oil or electric lamp burners.
