What is a stick barometer?

A stick barometer is a tall, narrow instrument that houses a vertical mercury tube. It shows direct atmospheric pressure changes through the exposed glass column. These pieces hung in hallways and libraries where occupants could check the weather before travelling.

How does a wheel barometer work?

A wheel barometer uses a float resting on the mercury inside a siphon tube. A silk thread and pulley connect this float to a needle on a circular dial. Changes in pressure turn the needle around the graduated face, making the reading easier to see from across the room.

Where were these barometers made?

Makers constructed these instruments in workshops across London and various British provincial towns. Many makers originated from Italian immigrant families who settled in Britain to practise instrument making. Their names appear engraved on the metal plates or painted on the dial faces.

What woods are used in the cases?

Cabinet-makers utilised dense tropical hardwoods such as mahogany and rosewood to construct stable housings for the delicate glass tubes. Boxwood often provided contrasting stringing and inlay details. These timbers protected the internal mechanics while offering a formal appearance suitable for period interiors.
