Storm Glass

  • €20.00

What is it?  
Predict the weather like Charles Darwin with Admiral Fitzroy's ingenious storm glass. The liquid inside the glass will indicate what the weather has in store. 

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 HMS Beagle. 

  • If the liquid in the glass is clear, the weather will be bright and clear.
  • If the liquid is cloudy, the weather will be cloudy as well, perhaps with precipitation.
  • If there are small dots in the liquid, humid or foggy weather can be expected.
  • A cloudy glass with small stars indicates thunderstorms.
  • If the liquid contains small stars on sunny winter days, then snow is coming.
  • If there are large flakes throughout the liquid, it will be overcast in temperate seasons or snowy in the winter.
  • If there are crystals at the bottom, this indicates frost.
  • If there are threads near the top, it will be windy.

    Glass, Beechwood, various chemicals & distilled water. Comes in a card box with instructions and is approx. 9.5 x 3 x 3 cm.
