Use this quality historical device, with its ever changing crystals, to forecast the weather.
The Storm Glass Barometer came into general use in the early 1700s by sailors who relied on it to predict fair or foreboding conditions at sea. It was further developed by Admiral Robert Fitzroy, captain of the HMS Beagle during its famous voyage with Charles Darwin. Fitzroy refined the chemical formulation and published observational guidelines on how the appearance of the liquid indicated changing weather conditions.
This special piece is hand-blown from glass in a stunning teardrop shape, and with its constantly evolving crystals, the Fitzroy's Teardrop Storm Glass make for an interesting and attractive room or desk ornament.

How Does It Work?
How this storm glass works is not fully understood. It is based on the principle that temperature and pressure affect solubility, sometimes resulting in clear liquid; other times causing precipitants to form.
It is said that the appearance of the liquid indicates the following weather conditions:Clear Liquid = Fair Weather
Murky Liquid = Rainy Weather
Crystals at the top = Thunderstorms
Large Flaky Crystals = Cloudy skies, snow in winter
Thread of Crystals = Windy weather
