STORMGLASS WEATHER FORECASTER
E.S. Sorensen

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.
This mysterious weather predictor has been used since 1750,
but how it works is still a mystery. 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
hermetically sealed glass chamber that holds the liquid (a mixture of distilled
water, potassium nitrate, ammonium chloride, alcohol and camphor), is encapsulated
in a polished brass or chrome cylinder.

This fine
stormglass, made in Denmark, is available
in either lacquered polished brass,
polished stainless steel, or matte stainless
steel. and comes with free ($27
value) matching hanging hook. SW 1 lb.
A wood plaque with brass stormglass
and brass plate showing details of operation
is also available SW 6 lb.
