HI ,
Your item is a spirit burner most probably early 20th century , lace makers lamps or (as they should be correctly referred to) Open Flame Oil Lamps in glass were commonly used as a simple lighting in the 17th and 18th century,they can be short or tall with and without handles , they can have a central hole for 1 wick usually held in place with a metal fitting , most of which have vanished over the years or the can be multi spouted ,up to 6 spouts have been recorded ,yes these were probably used by lace makers but none were ever filled with water , this function was fulfilled by very large reflecting globes very like large goldfish bowls on feet which were filled with water and an oil lamp was placed behind and the water filled bowl magnified the light .there is a very good book on the subject called The Open Flame-Lamp by Kieth Kelsall ISBN 0-9515120-1-3.
Cheers
Peter.
