Rayo & Rochester Lamp Chimneys
Frosted Glass Lamp Chimneys have a common fitter size to fit many old lamps. Frosted glass softens light output. These 3/4 frosted glass chimneys fit many Rayo , Rochester and other electric or oil lamp burners requiring a 2-5/8" bottom chimney. 10" height is a commonly used size.
Reminiscent of vintage glass:
Size and thickness of glass may vary slightly due to manufacturing processes. When multiples are ordered we match size and thickness providing a balanced harmonious appearance.
Glass is thin. Thickness mimics that on many antique chimneys. Use care when placing in burner/holder. Do not force glass chimney into holder.
Height is a matter of personal taste. Typically lamp chimney rises 2″-4″ above top of lamp shade.
Bottom diameter is measured outside edge to outside edge. Most burners have a narrow seat for chimney to rest on.
If having trouble getting an accurate diameter. Test by cutting a ring to 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. Make sure chimney fits securely if using on an oil lamp.
