Unique piece of French history. In 1844, the pendulum siphon was born thanks to Adrien-Emile-François Gabet. The balance siphon was a coffeepot consisting of two containers placed side by side, one in glass for coffee and the other in ceramic for water. To obtain coffee from this new coffee pot, the water was transferred through a tube from one of the containers to the other, to weigh down and trigger a pendulum to automatically turn off the burner at the appropriate time.Bronze frame, large glass receiver. Body and foot in white porcelain. The glass in perfect condition. The spout leading to the faucet of the porcelain water hold has had a repair. Nice faucet with dragon head. Mid 19th century style. Measures close to 15 inches tall with a 9.5 x 4.5 inch porcelain base.
