Storm Glass with Wooden Base

The storm glass forecasts the weather from clear days through to stormy and windy weather. The appearance of the liquid purportedly predicts the weather. A storm glass can create beautiful crystal structures that will fascinate children and adults alike and mean the storm glass will look great on display.

The storm glass barometer came into general use in the early 1700s. Sailors attached this instrument to the mast of their ships and by interpretation of the constantly changing crystal formations, relied upon it to forecast good weather and foreboding conditions at sea. Admiral Robert Fitzroy as commander of the HMS Beagle participated in the Charles Darwin's expedition and conducted a detailed study of this instrument. He refined the chemical formulation and published observational guidelines as indicated below

• Clear liquid - bright and clear weather
• Cloudy liquid - sometimes with small stars and crystals at the top cloudy weather and often predicts pending thunderstorms and rain
• Small dots in the liquid - humid or foggy weather
• Large flaky crystals - cloudy Skies snow in winter
• Threads of crystals at the top - windy Weather
• Crystals at the bottom - frost may be coming

How the storm glass really works is a mystery but it is believed that the electromagnetic changes in weather patterns activate the crystals inside (sealed glass chamber filled with crystals when air pressure decreases)
