This attractive German Jugendstil Art Nouveau copper and brass tea kettle dates to the early 1900s. It was made by the Gebruder Bing Company.
The kettle hangs from its original brass stand and has an alcohol burner at the base. The oval shape gooseneck kettle body has an organic repousse vines or branches decoration. The squared brass handle has a fixed coiled brass clutch in the center. Note the distinctive angled omega shape of the lid finial.
This type of kettle was called a spirit kettle, after the alcohol burners at the base of the holder. Although not marked that I can see, it is well documented as having been made by Gebruder Bing of Nuremberg Germany.
It holds about 3 cups and is 7-3/4" wide from shoulder to spout, 4-1/2 inches across the narrow side, and about 8 inches high to the top of the handle. The brass stand is a little over 14" high.
The burner is missing the wick cover and one post, and it is dented on one side. The base of the kettle has a few honest dings from use (see third to last picture, left side) but they're minor for a 100-plus year old teapot. If you plan to actually use the kettle, I would have the interior relined first. The lining has deteriorated where the hanging bolts attach, and it may contain lead.
