Tiffany Silver Soldered Object - What the heck is it?

[raibos]

Hi. I know who made it but I don't know what it is. Tiffany Makers, silver soldered. About 5.5" dia x 3.5" tall. The top of the little font or tank is open and threaded on the inside. I'm guessing it had a burner on top? The little arms are for snuffers?
