Ledro replica I used as a burner.  The thin pencil of flame rose in a steady jet 20 cm high. A replica of the rather differently shaped vessel from Bow Hill, in Sussex, could also be used as burner.  When raised on supports, the flame was 32cm high and burned form 15 minutes. A replica of the vessel from Biskupin, in Poland, was also used as a burner.  The flame rose 30 cm high and burned for 25 minutes.
