The storm glass was invented in the mid-1700s and soon made its way into several ships across Europe.
Care should be taken when making the storm glass as some of its constituents could be considered hazardous;
The video below shows how to make a Storm Glass;
“The changes in the solution signify the following:
- Clear liquid: Bright weather.
- Crystals at bottom: Thick air, frost in winter.
- Dim liquid with small stars: Thunderstorms.
- Large flakes: Heavy air, overcast sky, snow in winter.
- Threads in the upper portion of liquid : Windy weather.
- Small dots: Damp weather, fog.
- Rising flakes which remain high: Wind in the upper air regions.
- Small stars: In winter on bright, sunny days, snow in one or two days.
- The higher the crystals rise in the glass tube in winter the colder it will be.”
Below are some frequently asked questions about STORM GLASS;
How does one make a storm glass?
How to Make the Storm Glass
- Dissolve the potassium nitrate and ammonium chloride in the water.
- Dissolve the camphor in the ethanol.
- Add the potassium nitrate and ammonium chloride solution to the camphor solution.
- Either place the mixture in a corked test tube or seal it within a glass.
What does my storm glass mean?
A storm glass is a sealed device made of clear glass that contains chemicals that are said to crystalize in such a way to predict the weather a couple of days in advance. One to three days later, the observed weather should mimic the prediction from a couple of days back.
Does a storm glass work indoors?
Storm glasses are not intended for outdoor use, so if you purchase one, keep it indoors. They should also not be placed in a window that receives direct sunlight, or somewhere that may experience sudden temperatures changes during the day.
How do you reset a storm glass?
It is very important that you “reset” your storm glass after you receive it. To ‘reset” your storm glass, carefully lay it on its side on a large towel. Use a blow dryer to gently warm the glass while rolling it back and forth on the towel. Move the blow dryer in a side-to-side pattern to avoid overheating.
How long does it take for a storm glass to work?
About 15 minutes
It takes about 15 minutes of slowly heating and tilting the storm glass for the crystals to completely dissolve.
Does a storm glass really work?
Tests show it to be no better than a 50/50 chance of being correct, essentially leaving the predictions up to chance. Our opinion is that storm glasses should not be relied upon as a legitimate weather instrument but more of a conversation piece for your office or coffee table.
What liquid is in a storm glass?
A storm glass, also called a weather glass or camphor glass, is a glass tube containing a mixture of ammonium chloride, potassium nitrate, camphor, water, and alcohol, making a normally clear liquid in which different types of white crystals periodically grow and dissolve.
How do you read a storm glass?
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.
Where is the best place to put a storm glass?
Place the storm glass in a stable area of your house, away from air drafts, open windows, or direct sunlight. I found the best place to put it, and at the same time keep it away from little hands, is in my curio cabinet.
Does a storm glass have to be outside?
It is recommended that you place a storm glass indoors, on a level surface. It’s best for it to be next to a window that gets no direct sunlight. You should also keep your storm glass out of reach from your children. If you place it outdoors, it could easily break due to high winds or storms.
Is the liquid in a storm glass dangerous?
Most of the chemicals used to produce the liquid inside of a storm glass are potentially hazardous. Inhalation of these chemicals could make you sick, and you should take care when handling any of the chemicals and prevent exposure to bare skin.
How does storm glass barometer work?
A water barometer or storm glass is used to predict stormy weather. It works because of changes in atmospheric pressure. When air pressure sinks lower than when the body was sealed with water, the water level in the spout rises above the level in the body.
