Historical information
Gas lamps worked by heating something called a 'mantle' with a gas flame. The mantle then glowed brightly, lighting up the room. Lamps had either two chains, for a ceiling-mounted lamp or a tap for a wall-mounted burner to turn off the gas. These chains or taps could also adjust the flow of the gas and hence the brightness of the mantle.
Before Carl Auer von Welsbach invented the gas mantle in the 1890s, all gas lights in homes and street lights had simple gas jets that pointed upwards. In the home, these lights were covered with glass globes and had an overall ornate look making the lamp ascetically pleasing and protecting the flame from being blown out. However, this arrangement was extremely inefficient: To get as much light as possible, the gas had to be turned fully up, resulting in large sheets of flame rising towards a ceiling. Also, because the lamp had to be point upwards, the illumination was directed upwards, i.e. at the ceiling rather than where it was needed. So the usable light for a given amount of gas was minimal but the invention of the gas mantle eventually changed this. It enabled gas lights to have a small flame and to direct their light downwards.
Significance
The item is significant as it is part of a very ornate gas lamp wall bracket from the late 19th to early 20th century. Its provenance is currently unknown and at this time cannot be associated with a historical event, person or place and the item is assessed as a collective asset.
