Antique Slate Mantel Clocks

Antique Slate Mantel Clocks are small clocks made from slate, designed to be placed on shelves or a mantelpiece.


Brief history and description

Slate mantel clocks were incredibly popular in France during the 18th and 19th centuries, and typically needed to be wound in order for them to function properly. Many antique slate mantel clocks featured elaborate decorations and figurines, especially mantel clocks that were manufactured in France during the 17th century.

By the 19th century, mantel clocks were slowly becoming mass-produced in America thanks to Eli Terri, a clockmaker from Connecticut. Terri's mantel clocks were typically key-wound and sometimes featured a swinging pendulum made of wood.
