Selecting Lamp Chimneys

Oil Lamp Chimneys are used with or without a shade on antique lamps. Sometimes called glass globes or hurricanes these chimneys sit in a burner with tines or a chimney holder. The chimney is always put in burner first. The shade is then slipped over chimney.

Use Torpedo Shaped Light Bulbs inside chimneys. These bulbs are required as they consume less space which allows more air to circulate thereby reducing heat build up.

Chimneys are reminiscent of old glass: measurements are approximate, occasional slight imperfections and mold marks are normal and not defects. Shape may vary from picture.

Chimneys are measured bottom diameter by height.
  • Height is a matter of personal taste. Typically the oil lamp chimney extends up thru the middle of the lamp shade and rises 2″-4″ above the top of the shade.
  • Bottom diameter is measured outside edge to outside edge. This measurement is important as it must fit the holder or burner. Most burners have a narrow seat for chimney to rest on. Particular care should be taken if the lamp is used to burn oil making sure the oil lamp chimney bottom fits securely.
  • Measure the diameter of where a proper fitting chimney sits, once it is on the burner. This is best measured with calibers to get an accurate measurement. To test: cut a ring from paper the needed diameter. Slip down over burner to check fit.
  • Fit: The chimney should put slight pressure on the tines of the chimney holder or burner which in turn holds the oil lamp chimney in a stable position. This ensures a proper updraft enabling the burner to function correctly.

  • Height and shape of chimneys affect the general appearance of oil lamps.
  • Embossed, opal hobnail, and crimp top chimneys are typically used on lamps without a shade.
  • The simpler styles with straight tops are most often used on lamps with a shade.
