The Gasogene or Gazogene was a mid-19th century French device that varied in size from one quart to five gallons.  The device was used in for making carbonated water in the pharmacy. The lower globe contained water or other drink to carbonated, the upper a mixture of tartaric acid and sodium bicarbonate that reacts to produce carbon dioxide.  Both glass globes were surrounded by woven wicker mesh, as they had a tendency to explode.  The device is provided with a pewter spigot to dispense the contents.
