We should start off by pointing out that storm glass has been used as a clever and aesthetically-pleasing device that’s able to predict weather while maintaining an important decorative role as well. Historically, storm glass has been used by people around the world since the 18th century with various results. This is because a storm glass is only as effective as its build quality.
As you may be aware, the gadget relies on a specific chemical mixture that reacts to even the slightest changes in weather, thus changing its consistency in a way that signals how the weather will change. As such, the effectiveness of storm glass can differ from one model to another. Taking that into account, we put together a list of the ten best storm glass models the market has to offer at this point in time.

What To Look For In A Storm Glass
It goes without saying that most storm glass gadgets in existence operate on similar principles, thus the name. Even so, some are much more effective at predicting the weather than others, an effectiveness that can vary considerably from one model to another.
This can be observed in the mixture they contain and how fast it crystallizes or changes consistency over a specific period of time. While some do so immediately, others take hours to react, rendering the storm glass slightly ineffective. Over the next few minutes, we will try to learn more about what makes a storm glass effective and what particularities to consider when buying one.
How Does A Storm Glass Work?
A storm glass doesn’t usually incorporate any complex components or chemicals but a rather simple mixture that creates different transformations depending on a number of environmental factors. You can then interpret these transformations to deduce what change in temperature is most likely to occur. Speaking of which, the mixture commonly includes ethanol, distilled water, ammonium chloride, potassium nitrate, and camphor for the most part.
Even though there haven’t been too many tests done on the specifics of storm glasses, people have a very good understanding of how they work and what limitations they present. When certain changes occur in local humidity and temperature, the mixture develops various types of crystals that usually change shape of the course of 12-24 hours. We should also point out that sudden changes in atmospheric pressure will also result in the formation of these crystals.
How Accurate Are They?
It is important to remember that storm glasses aren’t supposed to replace weather stations or substitute them to any extent but rather to serve as a conversation piece or a cute decor item. Although perhaps not as legitimate as a professional weather station, a storm glass can still detect sudden changes in air pressure and humidity. On average, you can expect a storm glass to be a little over 50% efficient depending on how well it’s built and where you place it.
You also have to understand that storm glass predates modern weather stations by several centuries and that they were quite groundbreaking at the time. First used in 1850 by Captain Robert FitzRoy after his ship’s barometer broke down, this clever contraption showed to not only predict quick changes in weather but to do so with a decent enough accuracy to warrant its usage. Then again, you probably shouldn’t make plans according to the crystals in your storm glass if you can help it.
A storm glass works by predicting the weather up to 3 days in advance by using a special chemical mixture. This mixture contains ethanol, distilled water, ammonium chloride, potassium nitrate, and camphor. Of course, the mixture may change ever so slightly from one storm glass to another but their general purpose remains the same. You may also be required to first educate yourself on how to best interpret the crystal that forms inside the glass because the mixture changes form and consistency according to what type of weather it predicts to follow.
If you already possess a storm glass or if you’re thinking of buying one, then you should first find out how exactly you can use it to your advantage. As we said, the glass contains a mixture of chemicals that crystalize depending on subtle changes in atmospheric pressure and humidity. This process can cause the mixture to take multiple shapes, from crystal clear to small floating spots, each with its own interpretation and consistency.
In this respect, a cloudy crystalization with small stars means that the weather might change for the worst with high chances of thunderstorms. When the mixture is clear, the weather will most likely be sunny and fair. If the mixture changes to small isolated stars during winter there is a chance that it will snow in the following 1-2 days whereas large and isolated flakes represent cloudy weather with a high probability of snow. Now, if the mixture is cloudy, you will most likely experience rain soon, whereas small floating spots tell you that the weather will get foggy pretty soon.
Where To Place It
Although there’s a bit of a debate as to where storm glasses are most effective, it is certain that they need to be placed indoors in any case. The best thing to do is to place the glass somewhere inside the house where it doesn’t receive any direct sunlight during the day, else it might show false predictions on account of its constant exposure to heat. At the same time, try to keep the glass away from walls facing the outside or near heating/cooling ducts for obvious reasons.
