This Edwardian barograph from 1920 is made from warm brown oak, brass and glass, comprising a glazed display case housing an eight-chamber mechanism, a clockwork drum mechanism with a paper chart, and a brass recording arm. The oak case sits upon a stepped wooden base with short bracket feet and features moulded framing around the glass panels, an internal glass ink bottle, and a signed maker plaque on the base plate. Practical measurements are 20 cm high, 38 cm wide and 24 cm deep. In a contemporary home, this meteorological instrument suits a gentleman's library, study or office desk as a working scientific piece and decorative display item.

FAQs

A barograph is a recording barometer that continuously measures and records atmospheric pressure onto a paper chart wrapped around a clockwork-driven drum. Popularised in the late 19th and early 20th centuries, makers such as Negretti & Zambra were prominent British manufacturers of these meteorological instruments.

Antique barographs feature an aneroid capsule stack and brass mechanism housed inside a glazed wooden case, often constructed from oak, mahogany, or walnut, with bevelled glass panels.

Authentic Edwardian barographs feature makers marks or brass plaques from recognised manufacturers, hand-assembled brass clockwork movements, lacquered brass finishes, and period-correct glazed wooden cases with stepped bases.

A barograph functions as a decorative desk accessory or shelf accent, particularly when placed in a study, library, or entry hall alongside dark timber furniture and brass fittings.

Keep the instrument away from direct sunlight and heat sources to prevent the wooden case from warping, clean glass panels with a microfibre cloth, and use specialised brass polish sparingly to preserve original surface finishes.
