What is a Fitzroy Storm Glass and how do I read it?


According to Fitzroy’s findings, this glass barometer forecasts the weather based on changes in the formation of crystals inside the column. If the liquid 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 should be expected. A cloudy glass with small stars may indicate thunderstorms. If the liquid contains small stars on sunny winter days, expect snow. If there are large flakes throughout the liquid, it should be overcast in temperate seasons or snowy in the winter. Crystals at the bottom indicate frost. Threads near the top mean that it will be windy.

Examples of readings you may get on your storm glass:
  1. Fern-like Crystals Are Building Up: Cold Stormy
  2. Fern-like Crystals Are Disappearing: Improving Weather
  3. Star Crystals Are Falling Down: Frost and Maybe Snow
  4. Star Crystals Are All Over: Rain
  5. Clear Liquid: Clear & Dry

IMPORTANT INFORMATION ABOUT THIS PRODUCT: When you receive your Storm Glass, it will be in a state of disruption from the shipping process. It is very important that you “reset” it after you receive it. To “reset” your Storm Glass, find a vessel large enough to place your storm glass in. Fill the vessel with VERY HOT water and completely submerge the storm glass in this hot bath until ALL OF THE CRYSTALS INSIDE THE CYLANDER COMPLETELY DISSAPEAR. If all of the crystals fail to disappear, replace water in vessel with more VERY HOT water. Please no not use boiling water.

After you have cleared the entire column, place the Storm Glass in a secure location where it will not be bumped or moved. Due to the sensitive nature of the crystals inside the Storm Glass, you will want to avoid moving it unnecessarily. After the resetting process, you will need to wait up to 1 week to start seeing accurate readings. Repeat this resetting process at least 2 times a year, whenever you move it, or when you notice a lack of change within the glass.
