He had a great influence on mining and the steel production in Sweden. Life and work Rinman was born in Uppsala on 23 June(N.S) 1720. At the age of 20 he became an intern at the Royal Bureau of Mines. In the years 1746 and 1747 Rinman visited several European countries to improve his knowledge on mining and metallurgy. After his return he became inspector in several mines and metal works. His research on mining and metallurgy had a big influence on the Swedish industry.

Eskilstuna
Eskilstuna () is a city and the seat of Eskilstuna Municipality, Södermanland County, Sweden. The city of Eskilstuna had 67,359 inhabitants in 2015, with a total population of 100,092 inhabitants in Eskilstuna municipality (2014). Eskilstuna has a large Sweden Finn population. The town is located on the River Eskilstunaån, which connects Lake Hjälmaren and Lake Mälaren. History Eskilstuna's history dates back to medieval times when English monk Saint Eskil made "Tuna" his base and diocese of the South coast of Lake Mälaren. Saint Eskil was stoned to death by the pagan vikings of neighbouring town Strängnäs, east of Eskilstuna, trying to convert them to Christianity.

Cobalt Green
Cobalt green is an ambiguous term for either of two families of green inorganic pigments. Both are obtained by doping cobalt(II) oxide into colorless host oxides. Spinel-based cobalt green Doping Co(II) into Mg(II) and Zn(II) sites of Mg2TiO4 and Zn2TiO4, respectively gives one family of cobalt greens. These materials adopt the spinel structure.Völz, Hans G. ''et al.'' "Pigments, Inorganic" in ''Ullmann's Encyclopedia of Industrial Chemistry'', 2006 Wiley-VCH, Weinheim. . Rinman's green Rinman's green, also referred to as Rinmann's green, is obtained by doping cobalt(II) oxide into zinc oxide. Sven Rinman, a Swedish chemist, discovered this compound in 1780. Zinc oxide–derived pigments have been used in many industries and processes. It is rarely used because it is a weak chromophore and relatively expensive compared to chromium(III) oxide. The structure and color of compositions Zn1−xCoxO depends on the value of x. For x ≤ 0.3, the material adopts the Wurzite struc ...

Pigment
A pigment is a colored material that is completely or nearly insoluble in water. In contrast, dyes are typically soluble, at least at some stage in their use. Generally dyes are often organic compounds whereas pigments are often inorganic compounds. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli. Economic impact In 2006, around 7.4 million tons of inorganic, organic, and special pigments were marketed worldwide. Estimated at around US$14.86 billion in 2018 and will rise at over 4.9% CAGR from 2019 to 2026. The global demand for pigments was roughly US$20.5 billion in 2009. According to an April 2018 report by ''Bloomberg Businessweek'', the estimated value of the pigment industry globally is $30 billion. The value of titanium dioxide – used to enhance the white brightness of many products – was placed at $13.2 billion per year, while the color Ferrari red is valued at $300 million each year.
