Weather Glass Instrument
A weather glass instrument anticipates atmospheric shifts, bringing together practical science and decorative cabinet-making.
Weather Glass Instrument
A weather glass instrument is a traditional device designed to measure barometric pressure and forecast meteorological changes within domestic and maritime spaces. When you search for a weather glass instrument, you encounter barometers, barographs, and stick barometers spanning Georgian, Victorian, and Edwardian periods.
Materials and Construction
Cabinet makers utilised dense hardwoods such as mahogany, oak, walnut, satinwood, and rosewood to house delicate internal mechanisms, often incorporating carved wood details, bone fittings, or mother-of-pearl inlay. Glass and brass components protect the dials, thermometers, and rotating drums.
Internal setups combine mercury columns, aneroid movements, or mechanical paper chart drawers with graduated scales. Cases reflect the prevailing aesthetic of their era, moving from Georgian architectural lines to elaborate Victorian Black Forest carving and streamlined Art Deco forms.

Object forms span standard wall barometers, mercury stick barometers, clock combinations, and paper drum chart barographs.
Quality and Craftsmanship
The sculptural ambition of the exterior case also dictates worth, from simple geometric oak designs to deeply hand-carved Black Forest foliage and intricate mother-of-pearl inlay. A cohesive pairing of a working barometer or barograph with a matching thermometer elevates the piece.

The Weather Glass Instrument Glossary
- Barometer
- An instrument measuring atmospheric pressure used to forecast weather. These devices appear in stick, wheel, and aneroid formats.
- Barograph
- A recording barometer that plots pressure changes onto a revolving paper chart over time. They are typically housed in glazed wooden cases with chart drawers.
- Stick Barometer
- A tall, narrow barometer containing an exposed vertical tube of mercury and a silvered scale. Georgian and Victorian versions often feature architectural pediments.
- Aneroid Barometer
- A barometer that measures pressure using a flexible metal capsule rather than liquid mercury. This design allowed for more compact and varied domestic wall housings.
- Black Forest Style
- A heavily carved wooden decorative style originating from the European mountain region. These frames frequently incorporate naturalistic foliage and animal carvings.
Weather Glass Instrument: Frequently Asked Questions
What is a weather glass instrument?
A weather glass instrument is a historical atmospheric monitor used indoors to track barometric pressure changes.
These devices range from tall wooden stick barometers to compact aneroid dials and clock combinations.
How do stick and wheel barometers differ?
Stick barometers use a long vertical tube displaying mercury against a sliding scale for direct readings.
Wheel or banjo barometers use a pulley and cord system to turn a dial pointer based on internal pressure changes.
Where should I place a barometer?
Barometers suit hallways, studies, or living rooms away from direct heat sources and open windows.
Wall-mounted versions require secure fixings to support the weight of hardwood cases and glass components.
How do I identify the period of a barometer?
Georgian instruments often feature clean mahogany stick designs with architectural pediments and silvered brass plates.
Victorian and Edwardian models lean towards heavier carved oak, walnut, rosewood, and elaborate Black Forest ornamentation.
