Thunderglass with Cast Iron Holder

Product Description

Forget the weather app on your smartphone! This historically-inspired water barometer, also known as a "weather glass" or "thunderglass," shows one of the earliest known weather forecasting tools. The water level in the spout rises and falls with changes in atmospheric pressure. From the arrival of the first colonists in the early 1600s, fisherman, farmers and gardeners relied on this method for centuries to predict a coming storm.

A lovely combination of ingenuity and artfulness, this thunderglass comes with a cast iron filigree holder. Ink included, just add water for a striking display. This water barometer makes a unique gift item or a perfect accent for your colonial-inspired garden.

How to Use Your Thunderglass

Using methods originating from the 17th century, this thunderglass helps to monitor air pressure and predict rain. Fill the teardrop-shaped glass vessel with water and note its level in the spout. When there is high pressure, the water stays near the base of the spout and indicates good weather. As the air pressure drops, the water will rise in the tube, and will even drip out of the spout to warn you of an approaching storm.
