The gasogene (or gazogene or seltzogene) is a late Victorian era device for producing carbonated water. It consists of two linked glass globes: the lower contained water or other drink to be made sparkling, the upper a mixture of tartaric acid and sodium bicarbonate that reacts to produce carbon dioxide. The produced gas pushes the liquid in the lower container up a tube and out of the device. The globes are surrounded by a wicker or wire protective mesh, as they have a tendency to explode.
The earliest occurrence of the word noted in the Oxford English Dictionary dates from 1853, quoting a reference in Practical Mechanic's Journal on "Gaillard and Dubois' 'Gazogene' or Aerated Water apparatus". "gazogene", Oxford English Dictionary .
