Storm Glass Cloud

$35.00

A Storm Glass is a type of weather forecasting device composed of a sealed glass container filled with liquid. The appearance of the liquid purportedly predicts the weather.

The liquid within the glass is a mixture of several ingredients most commonly distilled, ethanol, potassium nitrate, ammonium chloride and camphor. This specific mixture was developed by Admiral Robert Fitzroy and used on his voyage with Charles Darwin on his HMS Beagle. During the historic voyage. Fitzroy carefully documented how the storm glass would predict the weather: If the liquid in the glass is clear, the weather be bright and clear. If the liquid contains small stars on sunny winter days, then snow is coming!

This Storm Glass Cloud is not only functional - it also makes for a beautiful gift!
