Storm glass + suspension brass

For optimum use, place the Stormglass in a cool place, for example in a north-facing window or on a boat. As the name suggests, the Stormglass is best at predicting stormy weather within the next 24- to 48-hour period. The Stormglass does not completely replace the barometer, but it is a good supplement. Always remember to listen to the weather forecast! The Stormglass is a highly valued object for everyday use and is a popular gift; an example of genuine Danish craftsmanship. 1.
