Description

For sale, a Late Victorian Law of Reflection Demonstration Apparatus.

Comprised of a black painted semi circular cast iron base with white painted scale divided to one hundred and eighty degrees. The central strut carries a candle holder and has a brass support to the back which carries two plane mirrors which can be adjusted to varying degrees around the scale.

A simple yet effective demonstration piece for showing the Law of Reflection on surfaces.

With its black painted finish, the apparatus is likely to have been manufactured by the company of Max Kohl. Their catalogues of the Edwardian period provide similar examples but this is sadly unmarked so not directly attributable, the only mark present on this piece is the serial number of 9350.

Nevertheless, a large, complete and fine example of its type.

Circa 1900

FAQs

These instruments were educational tools used in schools and universities during the nineteenth century to visually demonstrate fundamental laws of physics, mechanics, and optics to students.

Authentic nineteenth-century demonstration apparatuses typically combined heavy cast iron bases, brass fittings, glass mirrors, and hand-painted or engraved calibration markings.

Authenticity is determined by the presence of period-appropriate casting techniques, hand-engraved or stamped numeric scales, genuine patina on brass and iron components, and period glass mirror plates.

This piece works effectively as a sculptural focal point on a bookshelf, a desk, or a mantelpiece, bringing a sense of intellectual curiosity and industrial texture to a room.

Dust gently with a soft, dry microfibre cloth and avoid using harsh chemical polishes or water on cast iron and aged brass surfaces to preserve the original finish and protective patina.
