Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.
Cobalt-based blue pigments (cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was later thought to be due to the known metal bismuth. Miners had long used the name kobold ore (German for goblin ore) for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the kobold.
Today, some cobalt is produced specifically from one of a number of metallic-lustered ores, such as cobaltite (CoAsS). The element is, however, more usually produced as a by-product of copper and nickel mining.

Wellington (Māori: Te Whanganui-a-Tara [tɛ ˈfaŋanʉi a taɾa]) is the capital city of New Zealand. It is located at the south-western tip of the North Island, between Cook Strait and the Remutaka Range. Wellington is the major population centre of the southern North Island, and is the administrative centre of the Wellington Region, which also includes the Kapiti Coast and the Wairarapa. It is the world's southernmost capital of a sovereign state. Wellington features a temperate maritime climate, and is the world's windiest city by average wind speed.The position of Wellington as capital of New Zealand is not defined in legislation, but established by convention. Its metropolitan area, considered the greatest extent of Wellington itself, comprises four local authorities: Wellington City, on the peninsula between Cook Strait and Wellington Harbour, contains the central business district; Porirua on Porirua Harbour to the north is notable for its large Māori and Pacific Island communities; Lower Hutt and Upper Hutt are largely suburban areas to the northeast, together known as the Hutt Valley. The Wellington urban area, which only includes urbanised areas within Wellington City, has a population of 215,100 residents as of June 2020. The urban areas of the four local authorities have a combined population of 429,700 residents as of June 2020; this is what is usually considered to be Wellington's de facto full size, and that figure may be extended if the Kapiti Coast is included.
As the nation's capital since 1865, the New Zealand Government and Parliament, the Supreme Court, and most of the public service are based in the city. Architectural sights include the Old Government Buildings—one of the largest wooden buildings in the world—as well as the iconic Beehive, the executive wing of Parliament Buildings.
