like burners, come in different sizes and shapes. The
flange-base chimneys were produced to fit the coronet burner. The straight
sided chimneys fit the prong burners. The diameter of the chimney depended
on the diameter of the burner it was to fit. Some chimneys had oval
or rectangular bases to be able to fit into oval or rectangular burners.
The chimney guided the smoke up and away from the lamp and reflected
the light from the wick into the room.
Some chimneys are for sale with the purchase of a lamp. $5
