18th Century Water Barometer

18th century blown glass water barometer. This scientific object, sometimes called the “Goethe barometer,” was once used to predict weather changes based on atmospheric pressure. Its teardrop design is accentuated by a finely crafted spout, the height of which indicates changes in climate. The principle of this barometer is simple: when the water level is low in the spout, it predicts clear, stable weather. If the water level rises, it predicts worsening weather, and when it reaches its maximum level, it predicts the arrival of storms or unstable weather. This fascinating instrument, both functional and decorative, is designed to capture the essence of the science and aesthetics of its time.
