Inca Weather Glass

An early 1800s century maritime product with a lot of history, but in a new modern Danish design.

Inca Weather Glass from DenmarkLanding Boat Supply carries the full line of Inca Weather Glasses.

For centuries, this camphor filled glass has been a faithful squire for explorers, adventurers, living men, sailors, men and beasts, and even today is an unsolved mystery, but it works: The Weather Glass predicts the weather.

With its clean simple design, it is a beautiful classic as each captain, sailor, fisherman, etc. should have in his home. Each glass has its own unpredictable life, which in its own way shows the weather forecast. A special and inexplicable interaction between the natural camphor in the jar and cover in creates its own magic. This makes each Weather Glass unique.

FitzRoy – Father of The Weather Glass

The first documented use of a storm glass on a ship was the HMS Beagle’s 1831-1836 circumnavigation. Robert FitzRoy, father of the British Meteorological Service, captained the ship, and famed naturalist Charles Darwin was the ecology expert onboard. FitzRoy later published the various crystal patterns that would develop within a storm glass according to different wind directions and weather conditions. During FitzRoy’s historical voyage on the Darwin expedition, he carefully documented how the storm glass would predict the weather:

  • 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 a sunny winter day, 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.
