Title: A storm glass barometer. c. 1900.
Description: This storm glass barometer was made in Greenwich by Hudson & Son. Greenwich at the time helped to set the trend for British 18th-century instrument making. The storm glass barometer is a hermetically sealed glass bottle containing crystals of potassium nitrate and ammonium chloride in an alcoholic solution of camphor with some distilled water. It was claimed to be helpful to forecast changes in weather, although today the consensus is that this instrument is quite inaccurate.
