What is a weather glass barometer?

A weather glass barometer is a meteorological instrument designed to measure atmospheric pressure to help forecast local weather changes. These pieces combine scientific utility with decorative cabinetry. They utilise enclosed mercury columns or mechanical aneroid capsules to register rising or falling pressure. The results appear on engraved silvered dials or porcelain scales mounted inside timber cases.

Where should I hang a wall barometer?

Hang your barometer on an interior wall away from direct sunlight, radiators, and exterior doors. Sudden temperature fluctuations can affect the internal mechanics. Stable indoor conditions ensure the timber case remains protected and the pressure readings stay as accurate as possible. Secure fixings are essential, particularly for heavier mahogany and carved oak models.

How do I read an aneroid barometer?

Tap the glass lightly before reading to release any friction in the mechanical linkage. The primary hand points to the current atmospheric pressure. Set the movable pointer directly over the primary hand. Observing whether the main hand moves above or below this marker later indicates if pressure is rising or falling.
