The History of the Stormglass


    The original or true inventor of the Stormglass is still unknown. One of the first scientists who researched and developed the Stormglass in detail, was Admiral Fitzroy (1805 – 1865) who famously Captained Charles Darwin on his 1831 voyage in the H.M.S. Beagle -
    Fitzroy firmly believed, as did other scientists of the era, that the Stormglass could be used for weather prediction. Through his detailed studies and observations of the ever-changing crystal formations in the glass tube, he developed a system for weather prediction, making the following assertions:
If there are large flakes throughout the liquid, it will be overcast in temperate seasons or snowy in the winter.
If there are threads near the top, it will be warming or windy.
If the liquid contains small stars on sunny winter days, then snow is coming.
If there are crystals at the bottom, this indicates frost.
A cloudy glass with small stars indicates thunderstorms.
If the liquid in the glass is clear, the weather will be bright and clear.
    A comprehensive history of  the Stormglass is described by A. McConnell and P.Collins in the article:
