Historic “Storm Glass” Barometer

History

The Storm Glass, or Goethe Barometer, is regarded as the oldest
barometer in the world. Although Johan Wolfgang von Goethe is
sometimes credited with its invention, one was found in his bedroom
after his death, there is evidence that the Moors used similar
instruments during the 8

th

 century. Also called Thunder Glasses,

historians believe the early settlers sailed to the Americas using this
rudimentary barometer.

Using the Storm Glass

Each Storm Glass is hand blown and accurately forecasts changes in the
weather hours in advance. The Storm Glass should be filled with distilled
water which decreases the chance of streaks being left on the glass.
Using the enclosed tools filling the Storm Glass is a simple procedure.

1)  Fill a container will water
2)  Add food coloring to the water to make it easier to see in the Storm

Glass. Any color will do.

3)  Place the long injection tube onto the end of the syringe.
4)  Fill the syringe with the colored water.
5)  Insert the injection tube into the spout of the Storm Glass. The

tube should go completely down the spout and stop at the top of
the glass chamber. DO NOT INJECT THE COLORED WATER AT
THIS TIME.

6)  Hold the Storm Glass with one hand while holding the syringe with

the other. Turn the Storm Glass upside down.

7)  Slowly inject the colored water into the chamber of the Storm Glass

until it is about half full. See illustration above.

8)  Remove the injection tube from the main chamber & spout.
9)  Turn the Storm Glass back to its upright position and set it on a

flat surface
