Falu Red
Falun red or Falu red ( ; , ) is a red iron oxide pigment obtained as a byproduct of the Falun copper mine. It is traditionally used as a pigment in applied to exterior wood surfaces in Sweden, Finland, and Norway. ''Falu Rödfärg'' is a protected trademark, which may only be used for products containing red pigment sourced from the Falun Mine. ''Rödfärg'' ( Swedish), ''rödmylla'' (Finland Swedish) or ''punamulta'' ( Finnish) can refer to any flour paint containing either natural red ochre or industrial iron oxide pigments. History After centuries of copper mining in Falun, large piles of residual materials were deposited above ground near the mines. By the 16th century, mineralization of the mine's tailings and slag, added by smelters, began to produce a red-coloured sludge rich in copper, limonite, silicic acid, and zinc. When this sludge was heated for several hours and mixed with linseed oil and rye flour, it was found to create an excellent anti-weathering p ...

Kiruna Church
Kiruna Church (Swedish language, Swedish: ''Kiruna kyrka'') is a Church (building), church building in Kiruna, Sweden, and is one of Sweden's largest wooden buildings. The church was built between 1909 and 1912, designed by the architect Gustaf Wickman. The church exterior is built in a Gothic Revival style, while the altar is in Art Nouveau. History The church was built between 1909 and 1912, and consecrated by Bishop Olof Bergqvist on 8 December 1912. Since 1913, the church has been included in the Jukkasjärvi parish in the diocese of Luleå. Gustaf Wickman was the church's architect and the famous altarpiece is a work of Prince Eugen, Duke of Närke. Gustaf Wickman moved to Kiruna in 1899.

Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...

Shades Of Brown
Shades of brown can be produced by combining red, yellow, and black pigments, or by a combination of orange and black—illustrated in the color box. The RGB color model, that generates all colors on computer and television screens, makes brown by combining red and green light at different intensities. Brown color names are often imprecise, and some shades, such as beige, can refer to lighter rather than darker shades of yellow and red. Such colors are less saturated than colors perceived to be orange. Browns are usually described as light or dark, reddish, yellowish, or gray-brown. There are no standardized names for shades of brown; the same shade may have different names on different color lists, and sometimes one name (such as beige or puce) can refer to several very different colors. The X11 color list of web colors has seventeen different shades of brown, but the complete list of browns is much longer. Brown colors are typically desaturated shades of reds, oranges, an ...

Dalarna
Dalarna (; ), also referred to by the English exonyms Dalecarlia and the Dales, is a (historical province) in central Sweden. Dalarna adjoins Härjedalen, Hälsingland, Gästrikland, Västmanland and Värmland. It is also bordered by Norway in the west. The province's borders mostly coincide with the modern administrative Dalarna County (). The area is a holiday destination for Swedes from the south, who often travel there in the summer, drawn by its fishing lakes, campgrounds, and forests. Some Swedes own or rent a second home in Dalarna, where vegetable gardens and apple trees are commonplace. In mid-June, midsummer celebrations and dances are held in many of the small villages and in the larger cities. Dalarna is a region full of historical associations, and both its products and its people have strong local characteristics.

Iron Oxides
An iron oxide is a chemical compound composed of iron and oxygen. Several iron oxides are recognized. Often they are nonstoichiometric, non-stoichiometric. Ferric oxyhydroxides are a related class of compounds, perhaps the best known of which is rust. Iron oxides and oxyhydroxides are widespread in nature and play an important role in many geological and biological processes. They are used as iron ores, pigments, Catalysis, catalysts, and in thermite, and occur in hemoglobin. Iron oxides are inexpensive and durable pigments in paints, coatings and colored concretes. Colors commonly available are in the "earth tone, earthy" end of the yellow/orange/red/brown/black range. When used as a food coloring, it has E number E172. Stoichiometries Iron oxides feature as ferrous (Iron(II), Fe(II)) or Iron(III), ferric (Iron(III), Fe(III)) or both. They adopt Octahedral molecular geometry, octahedral or Tetrahedral molecular geometry, tetrahedral coordination geometry. Only a few oxide ...

Linseed Oil
Linseed oil, also known as flaxseed oil or flax oil (in its edible form), is a colorless to yellowish oil obtained from the dried, ripened seeds of the flax plant (''Linum usitatissimum''). The oil is obtained by pressing, sometimes followed by solvent extraction. Owing to its polymer-forming properties, linseed oil is often blended with combinations of other oils, resins or solvents as an impregnator, drying oil finish or varnish in wood finishing, as a pigment binder in oil paints, as a plasticizer and hardener in putty, and in the manufacture of linoleum. Linseed oil use has declined over the past several decades with increased availability of synthetic alkyd resins—which function similarly but resist yellowing.

Crofter
A croft is a traditional Scottish term for a fenced or enclosed area of land, usually small and arable, and usually, but not always, with a crofter's dwelling thereon. A crofter is one who has tenure and use of the land, typically as a tenant farmer, especially in rural areas. In Northern England, ''crofter'' was a term connected with tenant farming and rural employment. For example in the textiles industry; someone who bleached cloth prior to dyeing, laying it out in fields or 'crofts'. Etymology The word ''croft'' is West Germanic in etymology, derived from the Dutch term ''kroft'' or ''krocht'' and the Old English ''croft'' (itself of debated origin), meaning an enclosed field. Today, the term is used most frequently in Scotland, most crofts being in the Highlands and Islands area. Elsewhere the expression is generally archaic. In Scottish Gaelic, it is rendered (, plural ). Legislation in Scotland The Scottish croft is a small agricultural landholding of a typ ...

Farmer
A farmer is a person engaged in agriculture, raising living organisms for food or raw materials. The term usually applies to people who do some combination of raising field crops, orchards, vineyards, poultry, or other livestock. A farmer might own the farmland or might work as a laborer on land owned by others. In most developed economies, a "farmer" is usually a farm owner ( landowner), while employees of the farm are known as '' farm workers'' (or farmhands). However, in other older definitions a farmer was a person who promotes or improves the growth of plants, land, or crops or raises animals (as livestock or fish) by labor and attention. Over half a billion farmers are smallholders, most of whom are in developing countries and who economically support almost two billion people. Globally, women constitute more than 40% of agricultural employees. History Farming dates back as far as the Neolithic, being one of the defining characteristics of that era. By the Bronze ...

Calcination
Calcination is thermal treatment of a solid chemical compound (e.g. mixed carbonate ores) whereby the compound is raised to high temperature without melting under restricted supply of ambient oxygen (i.e. gaseous O2 fraction of air), generally for the purpose of removing impurities or volatile substances and/or to incur thermal decomposition. The root of the word calcination refers to its most prominent use, which is to remove carbon from limestone (calcium carbonate) through combustion to yield calcium oxide (quicklime). This calcination reaction is CaCO3(s) → CaO(s) + CO2(g). Calcium oxide is a crucial ingredient in modern cement, and is also used as a chemical flux in smelting. Industrial calcination generally emits carbon dioxide (). A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature processing (550–1150 °C, or 1000–2100 °F) within a controlled atmosphere.
