Timișoara (UK: /ˌtɪmɪˈʃwɑːrə/, US: /ˌtiːmiː-/, Romanian: [timiˈʃo̯ara] ; see other names) is the capital city of Timiș County, Banat, and the main economic, social and cultural center in Western Romania. Located on the Bega River, Timișoara is considered the informal capital city of the historical Banat region. From 1848 to 1860 it was the capital of the Serbian Vojvodina and the Voivodeship of Serbia and Banat of Temeschwar. With 250,849 inhabitants at the 2021 census, Timișoara is the country's fifth most populous city. It is home to around 400,000 inhabitants in its metropolitan area, while the Timișoara–Arad metropolis concentrates more than 70% of the population of Timiș and Arad counties. Timișoara is a multicultural city, home to 21 ethnic groups and 18 religious denominations. Historically, the most numerous were the Swabian Germans, Jews and Hungarians, who still make up 6% of the population in Timișoara.

Conquered in 1716 by the Austrians from the Ottoman Turks, Timișoara developed in the following centuries behind the fortifications and in the urban nuclei located around them. During the second half of the 19th century, the fortress began to lose its usefulness, due to many developments in military technology. Former bastions and military spaces were demolished and replaced with new boulevards and neighborhoods. Timișoara was the first city in the Habsburg monarchy with street lighting (1760) and the first European city to be lit by electric street lamps in 1884. It opened the first public lending library in the Habsburg monarchy and built a municipal hospital 24 years ahead of Vienna. Also, in 1771 it published the first German newspaper in Southeast Europe (Temeswarer Nachrichten). In December 1989, Timișoara was the starting point of the Romanian Revolution.

An incandescent gas mantle, gas mantle or Welsbach mantle is a device for generating bright white light when heated by a flame. The name refers to its original heat source in gas lights which illuminated the streets of Europe and North America in the late 19th century. Mantle refers to the way it hangs like a cloak above the flame. Gas mantles are also used in some portable camping lanterns, pressure lanterns and some oil lamps.

Gas mantles are usually sold as a fabric bag which, because of impregnation with metal nitrates, burns away to leave a rigid but fragile mesh of metal oxides when heated during initial use; these metal oxides produce light from the heat of the flame whenever used. Thorium dioxide was commonly a major component; being radioactive, it has led to concerns about the safety of those involved in manufacturing mantles. Normal use, however, poses minimal health risk.

Kimberley (Khoekhoe: ǃ’Ās; Tswana: Kimbali) is the capital and largest city of the Northern Cape province of South Africa. It is located approximately 110 km east of the confluence of the Vaal and Orange Rivers. The city has considerable historical significance because of its diamond mining past and the siege during the Second Boer War. The British businessmen Cecil Rhodes and Barney Barnato made their fortunes in Kimberley, and Rhodes also established the De Beers diamond company in the early days of the mining town.

On 2 September 1882, Kimberley became the first city in the Southern Hemisphere and the second in the world after Philadelphia, in the United States, to install electric street lighting. The first stock exchange in Africa was built in Kimberley as early as 1881.
