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.
Our glass chimneys are made of borosilicate glass. This unique glass is resistant to temperature changes making it ideal for lighting.
Glass is thin. Thickness mimics that on many antique chimneys. Use care when placing in burner/holder. Do not force glass chimney into holder.
Reminiscent of vintage glass, occasional minor variations in appearance, overall size and thickness of glass may occur.
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.
