The Royal Navy's famous meteorologist, Admiral Fitzroy, who sailed with Charles Darwin aboard the Beagle, made extensive observations of weather using barometers and the stormglass. How the barometer works, and what it tells about the weather, are well documented, but not so for the stormglass.

It is believed that the stormglass responds to electromagnetic fluctuations caused by weather and by solar storms. The appearance of the crystals inside the glass foretells changes in the coming weather.

The sealed glass chamber that holds the crystals is encapsulated in a polished brass or chrome cylinder. While it can be displayed free standing, it is best mounted to a wall using the mounting bracket shown. This fine stormglass, made in Denmark, is available by itself or with the mounting bracket in either brass or polished stainless steel.
