Nautical Collection Storm Glass
A storm glass was first used in the 1750s to predict weather changes. The instrument much like the Nautical Collection Storm Glass was used by seamen who mounted it on the mast of their ship. It was intended to be a storm-warning instrument so sailors could prepare themselves. Observations suggest that the changes in the crystalline structure are triggered by changes in temperature and electrostatic charges. Unfortunately the changes in crystals are too small indoors to use the instrument as a reliable forecaster. Still it is a mysterious and beautiful instrument that adds historic appeal to your home.This reproduction consists of a hand-blown hermetically sealed glass cylinder filled with camphor alcohol and water. Changes in the weather cause changes in the crystals. When the weather is fine the crystals settle at the bottom. When the weather is foul the crystals rise to the top. The famed Admiral Fitzroy devised a set of rules for predicting weather based on the appearance of the crystals. These rules are printed on the mounting below the glass.The storm glass measures 12.5 inches tall by five inches wide. The back is enclosed with a recessed hanger for easy flat hanging. Features a frame in a dark oak finish.
