Custom, hand-made "Little" chimney made from thick borosilicate glass, copy of the famous Macbeth 2 1/2 (26) chimney.  1.445" fitter. For the Bijou, Little Jewel, Little Prince, Little Royal, Young America.

Rare original chimneys were duplicated in shape to ensure the designed characteristics were retained. 

Our chimneys are made in the USA from borosilicate glass, thick, defect free, and can take the heat generated by  lamps without breaking.

Borosilicate glass is a type of glass (Pyrex) with the main glass-forming constituents silica and boron oxide. Borosilicate glasses are known for having very low coefficients of thermal expansion (~5 × 10−6 /°C at 20°C), making them resistant to thermal shock, more so than any other common glass.

 

Chimneys are selected to fit on the chimney "seat," the flat ledge between the INSIDE of the chimney fingers and the burner cone. A chimney is NOT chosen based on measurements from the outside of opposing chimney fingers - chimneys are chosen to fit the lamp, not to fit what can frequently be incorrectly adjusted chimney fingers.
