When I first started writing looking at storm glass reviews got me thinking. Crystals in a glass vase filled with liquid can predict the weather? Like you, maybe, I was pretty skeptical about this so-called storm glass at first. But as I started to do my research, I realized there’s more to this than just a gimmick – the science behind it is pretty interesting!
A storm glass, also known as a camphire glass or a chemical barometer, is a device for predicting the weather. It was invented by an unknown inventor in the 18th Century and wildly popularized by Admiral Robert FitzRoy, who used it on his voyages with the HMS Beagle. He later became the governor of New Zealand and the founder of the UK Met Office.
This guide will look at the top five storm glass reviews and help you choose the right one for your needs. We’ll also answer some of the most frequently asked questions about storm glasses.
Storm Glass Reviews
- This traditional weather station is both a work of art and an instrument at home in any fine study, library, office or upscale restaurant. The rich, wood framed classic weather station measures barometric pressure (liquid). The antique weather station displays an air of quality and accuracy one would expect with a fine, handcrafted weather instrument from Ambient Weather.
- The concept that 'decreasing atmospheric pressure predicts stormy weather' was postulated by Lucien Vidie -- and it's the basis for a weather prediction device called a storm glass or liquid barometer. It consists of a glass container with a sealed body, half filled with water.
- A narrow spout connects to the body below the water level and rises above the water level, where it is open to the atmosphere. When the air pressure is lower than it was at the time the body was sealed, the water level in the spout will rise above the water level in the body and when the air pressure is higher, the water level in the spout will drop below the water level in the body.
- Also includes a comfortmeter, which measures temperature and humidity, and a comfort zone indicator.
- Includes 1 year Ambient Weather Warranty

How does a storm glass work?
Weather predicting storm glass is a weather prediction device used for centuries. These devices are said to be able to forecast the weather by the way the liquids inside them change.
Storm glasses are made up of four different liquids of different densities, each responding to changes in pressure and temperature differently. As the weather changes, the liquids separate or combine to form various patterns.
For example, if the liquid in the storm glass is clear, it indicates fair weather conditions. If the fluid is cloudy, it is supposed to signal that a storm is coming. While no scientific evidence supports these claims, many believe storm glasses can be used as a primitive weather forecast.
Admiral FitzRoy Storm Glass Predictor liquid meanings;
- A clear liquid means bright and clear weather
- A cloudy liquid means cloudy weather with precipitation
- Small dots mean humid or foggy weather
- Stars in a cloudy glass mean thunderstorms
- Large flakes mean overcast or snowy weather
- Crystals at the bottom mean frost
- Threads near the top mean wind
- Threads on top meant wind
Whether or not they work, storm glasses make for fascinating pieces and can add a bit of intrigue to any room.
How does storm glass work in the 21st Century?
Fast forward to modern times, storm glass predictors are still available for purchase, although they once were more popular than they were. You can find them online and in some stores, but they are less common than other weather forecast tools like barometers.
While the technology behind storm glass predictors has not changed much since they were first invented, our understanding of how they work
Liquids inside the storm glass expand or contract as the temperature and pressure change. This reaction causes the separation or combining of crystals to form different patterns. While these patterns may be able to give us some clues about the weather, they are only sometimes accurate.
What To Consider When Purchasing A Weather Glass Predictor
Before you make your final section consider the following:
Size
Determine the size of storm glass you’re looking for. Most of the glass on the market is shaped like a cylinder and can range in size from 6 to 10 inches.
Style
Traditional storm glass comes in various styles, including nautical, coffee table, antique, and modern. You can also find glass that’s inscribed with words or quotes.
Location of Weather Predicting Storm Glass
This is the critical part of selecting the perfect storm glass. It needs to be placed in an area where it will not be disturbed and where it will be out of direct sunlight. Pick a location away from small kids who might break the glass and get hurt.
Price
The price of a storm glass can vary depending on the quality and brand. You can expect to pay anywhere from $20 to $100 for decent quality storm glass.
When selecting a weather glass predictor, size, style, location, and price are all important factors.
How do you make a simple storm glass?
Below are the steps involved, but buying a ready-made unit is highly recommended.
- In a small saucepan, dissolve the potassium nitrate and ammonium chloride in water.
- In a separate container, dissolve the camphor in ethanol.
- Add the potassium nitrate and ammonium chloride to the camphor solution.
- Pour the mixture into a corked test tube
A good source with visual steps for making a homemade chemical weather glass.
Where should a storm glass be placed?
A storm glass work indoors should be placed in a stable, level location away from direct sunlight, drafts, heat, or cold. The storm glass mustn’t be disturbed, as this can cause inaccurate readings.
A window sill is a popular location as long as it meets the above criteria.
Some people believe that storm glasses are more accurate when placed near the ocean, as the salty air is thought to affect the crystals.
Others believe that storm glasses work best when placed in an area with a consistent temperature, such as a basement.
There is no scientific evidence to support either of these claims. They can not be relied upon for weather predictions, and their chances of being correct are like flipping a coin.
The bottom line is that you should place your storm glass where it will not be disturbed and where it will be out of direct sunlight.
What do the different shapes in a storm glass mean?
The shape of the crystal growth in a storm glass weather predictor can give you some clues about the weather, but they are not always accurate.
The following shapes have been traditionally associated with specific weather conditions:
Needles: rain or snow is coming
Plates: fair weather is on the way
Threads: humid weather is coming
Flowers: a storm is coming
Hair: a windy day is coming
Again, there is no scientific evidence to support these outcomes.
The bottom line is that you should not rely solely on the shapes in a storm glass to predict the weather. Adding a home weather station will give you more weather data points such as barometric pressure, temperature, wind speed, and direction.
How do you activate storm glass?
When you first set up your storm glass weather predictor, allow at least two weeks for the glass to adjust to its new environment before making any predictions.
The weather predicting storm glass will go through a settling period as the chemicals inside the glass rearrange themselves. During this time, you may see some sediment at the bottom of the glass.
Once the storm glass has settled, you can observe the crystal’s changes to predict the weather.
Are storm glasses accurate? Storm glasses are not considered to be accurate predictors of the weather. They are more of a novelty item than a reliable source of weather information.
Conclusion
As I said at the onset of this article, the storm glass is more of a novelty item than an accurate weather predictor.
That being said, they are still fun to have and make for a great conversation piece. I can see the appeal of a storm glass for someone who loves the mystery of weather prediction and enjoys seeing the changes in the crystals.
If you are looking for an accurate weather prediction, I recommend adding a home weather station to your arsenal of weather tools. Home weather stations measure many different data points that can give you an accurate forecast.
Others believe that storm glasses work best when placed in an area with a consistent temperature, such as a basement.
There is no scientific evidence to support either of these claims. They can not be relied upon for weather predictions, and their chances of being correct are like flipping a coin.
The bottom line is that you should place your storm glass where it will not be disturbed and where it will be out of direct sunlight.
FAQs
How do you activate storm glass?
To activate a storm glass, you must first allow it to adjust to its new environment for at least two weeks. During this time, you may see some sediment at the bottom of the glass. The storm glass has settled; you can observe the crystal’s changes to predict the weather.
How long does it take a storm glass to work?
Storm glasses generally take about 3-5 days to start working but can sometimes take up to two weeks. The time it takes for your storm glass to adjust to its new environment and start showing changes in the weather will depend on a few factors, such as the temperature and humidity of the room, how often the glass is moved, and whether or not the seal is tight. Once your storm glass has adjusted, you should start to see changes.
How do I know if my storm glass is working?
After the adjustment period is over with no results in crystal changes, you can try this simple test. Put the storm glass in the refrigerator for about 2 hours. If crystals start to form, your storm glass is working, and you can begin using it to predict the weather!
What happens if a storm glass breaks?
If a storm glass container breaks, the liquid and crystals inside may spill out. It is best to clean it up immediately if this happens. The glass can be recycled or thrown away—a safety tip. Please keep away from flames or heating as it may release gas fumes. Wash hands or skin with soap and water and rinse thoroughly.
How do you clean a storm glass?
To clean a storm glass, rinse it with distilled water and let it air dry. You can also use a soft cloth to wipe away any dirt or fingerprints. Do not use soap or other cleaners as they may damage the glass.
Is storm glass toxic?
Storm glasses are not toxic, but it is best not to ingest them and wash your hands after contact to be on the safe side. The chemicals will cause skin irritation. Keep out of reach of kids.
Do storm glasses really work?
Some people think storm glasses can help them predict the weather, but there is no evidence that they are accurate. They’re more of a conversation starter than anything else.
