Fitzroy’s Storm Glass 28cm

Step back in time and discover the fascinating world of weather prediction with the FitzRoy's Storm Glass. This elegant scientific instrument is inspired by one of history's most intriguing forecasting tools, allowing users to observe changing crystal formations inside a sealed glass vessel. While modern meteorology has replaced storm glasses for accurate forecasting, they remain a captivating way to explore the science and history of weather.

Originally popular in the 19th century, storm glasses became famous through Vice Admiral Robert FitzRoy (1805–1865), a pioneering meteorologist and captain of HMS Beagle during Charles Darwin's famous voyage around the world. FitzRoy was one of the first people to develop systematic weather forecasting and encouraged the use of storm glasses aboard ships to help predict approaching weather conditions.

As atmospheric conditions change, the liquid inside the storm glass forms different crystal patterns. Traditionally, these formations were believed to indicate changing weather:

• Clear liquid – Bright, clear weather
• Cloudy liquid – Overcast skies or possible rain
• Small crystals – Humid or foggy conditions
• Large flakes or star-shaped crystals – Cold weather or snow (in suitable climates)
• Threads or crystals rising – Windy weather

Today, the FitzRoy's Storm Glass is valued as both a decorative conversation piece and an engaging educational resource that introduces learners to the history of meteorology, observation skills, and scientific curiosity.
