Elegantly set for wall or table-top, display your FitzRoy storm glass with the information needed to interpret it! This screened plaque shows the figures originated by Admiral FitzRoy to 'read' the glass. Mounted on a wood base and accompanied by a laquered brass storm glass hook, your storm glass will really be beautifully showcased.

A storm glass is a type of weather-forecasting device, composed of a sealed glass container, filled with liquid, that allows the user to forecast the weather by observing the appearance of the liquid in the glass.

The liquid within the glass is a mixture of several ingredients, most commonly distilled water, 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 the HMS Beagle.

1. If there are large flakes throughout the liquid, it will be overcast in temperate seasons or snowy in the winter.
2. If there are threads near the top, it will be warming or windy.
3. If the liquid contains small stars on sunny winter days, then snow is coming.
   If there are crystals at the bottom, this indicates frost.
4. A cloudy glass with small stars indicates thunderstorms.
5. If the liquid in the glass is clear, the weather will be bright and clear.

The photograph to the left was taken prior to a winter storm that brought freezing rain and sleet to us. It was snowing just west of us and raining to our east. Take a look at a really big (1500x2450) image of the FitzRoy storm glass before an ice, sleet, and snow event. Further information on this type of storm glass is found in a set of articles by Sergey P. Fediaev entitled Observation Over Work of the Device "STORM GLASS" (translated from Russian by M. Dvoretskaya).

A displayed FitzRoy storm glass is shown in the photograph. Gift wrap orders: input salutation in the comment section at the end of the ordering process. View giftwrap paper choices.
