Context

Country: Canada
State/Province: Unknown
Period: circa 1920
Canada: An example of a ceiling rosette of a type used in Canada. Part of a large and varied collection of over 7500 electrical items acquired and documented by Ontario Hydro in the1960s. The collection was thought to be the largest and most comprehensive of its kind in Canada and was donated to the National Museum of Science and Technology in 1992.
Function: An electrical wiring device used to provide a means of connecting electrical wires coming from the wiring system of a building into a single wire or cable and also to provide a decorative cover from which this wire can emerge.
Technical: An example of a porcelain ceiling rosette of the circa 1920. According to Mellanby (Ref. 2), no sooner had the rose been invented than it was also used to house a fuse, an exceedingly inconvenient arrangement. However this helped to draw attention to the need for a better material than wood, and china soon became the standard material. The familiar china screw-on cover was one of the earliest innovations due to the General Electric Co. During the 1990s, porcelain barriers were added between the poles. While the normal rose provided a reasonably efficient method of connecting a pendant. In most domestic installations its use was confined to the bedrooms and 'usual offices', the more ornamental fittings in sitting rooms being provided with metal ceiling plates which were considered to be better looking.
