If you’re unsure what storm glass is, it is a small weather-predicting device known as a pinpoint weave or camphor weather glass. Born out of the 1800’s, the idea is to reflect the temperature around you, similar to how a barometer or thermometer works. As the temperature drops, crystals will form in the glass; over time, those crystals can grow into long blades that are incredible to see. However, it is not very accurate for actual weather prediction. Storm glass is more about a beautiful display while showing temperature fluctuations. Knowing how to get the best visuals from your storm glass will make ownership a much more enjoyable and predictable experience. This is why writing this short storm glass guide made sense so you, too, can have a great experience. 

Storm Glass Guide

1: Warm to Cold

If you keep your glass indoors, chances are the temperature is relatively consistent at somewhere between 65-75 degrees. At this temperature the storm glass will typically have flakes along the bottom with an otherwise clear liquid above. Cold air is what brings the storm glass to life so all you need to do is either stick it in the fridge for 15 minutes, or set it outside if the temperature is below 60 to see it pop.

2: The Window Sill Guide — Best for Accuracy!

The window sill is my favorite place to recommend placing the storm glass if you want it acclimated to the weather outside. Generally, a safe place to keep it is behind a window screen as it is protected from rain and won’t fall. You might have a better place to keep yours, so use your best judgment to find the best viewing experience for yourself. I know a lot of folks who like to keep theirs in the kitchen window above the sink, and they get some super cool looking crystal growth over time.

3: Change the Temps!

Keeping the storm glass in a cold environment will eventually fill it full with what appear to be crystals. If you’d like some space to see the clear liquid with suspended ‘snow flakes’ consider bringing it indoors to warm up. Then once it’s clear, put it back into a cold environment and watch as it pops after a few minutes.

My favorite state is when the storm glass is clear with flakes that resemble snow, suspended in the liquid as if time stopped. And I’m going to give you a few ideas to try out to get there too.

You can get this visual when the storm glass goes from a warm environment in the 65-70 range and drop it down to the 50s,40s,30s. At that point, crystals will start to form throughout the glass like the image below.
