Silicate Mineral Paint
Silicate mineral paints or mineral colors are paint coats with mineral binding agents. Two relevant mineral binders play a role in the field of colors: Lime and silicate. Under influence of carbon dioxide, lime-based binders carbonate and water silicate-based binders solidify. Together they form calcium silicate hydrates. Lime paints (aside of Fresco-technique) are only moderately weather resistant, so people apply them primarily in monument preservation. Mineral colors are commonly understood to be silicate paints. These paints use potassium water glass as binder. They are also called water glass paints or Keimfarben (after the inventor). Mineral silicate paint coats are considered durable and weather resistant. Lifetimes exceeding a hundred years are possible. The city hall in Schwyz and "Gasthaus Weißer Adler" in Stein am Rhein (both in Switzerland) received their coats of mineral paint in 1891, and facades in Oslo from 1895 or in Traunstein, Germany from 1891.

Lime (material)
Lime is a calcium-containing inorganic material composed primarily of oxides and hydroxide, usually calcium oxide and/or calcium hydroxide. It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. The word ''lime'' originates with its earliest use as building mortar and has the sense of ''sticking or adhering''. These materials are still used in large quantities as building and engineering materials (including limestone products, cement, concrete, and mortar), as chemical feedstocks, and for sugar refining, among other uses. Lime industries and the use of many of the resulting products date from prehistoric times in both the Old World and the New World. Lime is used extensively for wastewater treatment with ferrous sulfate. The rocks and minerals from which these materials are derived, typ ...

Alte Pinakothek
The Alte Pinakothek (, ''Old Pinakothek'') is an art museum located in the Kunstareal area in Munich, Germany. It is one of the oldest galleries in the world and houses a significant collection of Old Master paintings. The name Alte (Old) Pinakothek refers to the time period covered by the collection—from the fourteenth to the eighteenth century. The Neue Pinakothek, re-built in 1981, covers nineteenth-century art, and Pinakothek der Moderne, opened in 2002, exhibits modern art. All three galleries are part of the Bavarian State Painting Collections, an organization of the Free state of Bavaria. The building King Ludwig I of Bavaria ordered Leo von Klenze to erect a new building for the gallery for the Wittelsbach collection in 1826. The Alte Pinakothek was the largest museum in the world and structurally and conceptually well advanced through the convenient accommodation of skylights for the cabinets. Even the Neo-Renaissance exterior of the Pinakothek clearly stands out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthen Plaster
Earthen plaster (adobe plaster, dagga) is a blend of clay, fine aggregate, and fiber. Other common additives include pigments, Lime (mineral), lime, casein, prickly pear cactus juice (''Opuntia''), manure, and linseed oil. Earthen plaster is usually applied to masonry, cob (material), cob, or Straw-bale construction, straw bale interiors or exteriors as a wall finish. It provides protection to the structural and insulating building components as well as texture and color. Physical composition All plasters and stuccos have several common features: they all contain a structural component, a binding element, and some form of fiber. Usually the term plaster refers to a wall covering made from earth, Lime (mineral), lime or gypsum, while stucco uses a cement or synthetic binding element. Clay: the binding agent Clay is a soil component consisting of extremely fine particles. Most clays consist of hydrous aluminum silicates, though there is a considerable amount of chemical varia ...

Callwey Verlag
The Callwey Verlag is a German publishing house with the main focus on structural engineering and architecture. History The publishing house was founded in 1884 in Munich by Georg D.W. Callwey. Callwey published books based on the subjects of planning and design around the house, lifestyle, living, design, architecture, landscape architecture, crafts and restoration. They offered an extensive book program on the subjects of building, housing, gardening and cooking, and various journals about the field of architecture and craft such as "Der Baumeister" (The Builder), "Garten und Landschaft" (Garden and Landscape), "Topos", "Die Mappe" (The Folder), "Stein" (Stone) and "Restauro". In addition, they offered digital products, events, awards, symposia, yearbooks and services of corporate publishing. Callwey Verlag gained national prominence when Ferdinand Avenarius took over 50% of the stakes in the magazine "Der Kunstwart", in 1894, which was at that time an important publication o ...

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siliceous
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula , most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as a synthetic product. Notable examples include fused quartz, fumed silica, silica gel, opal and aerogels. It is used in structural materials, microelectronics (as an electrical insulator), and as components in the food and pharmaceutical industries. Structure In the majority of silicates, the silicon atom shows tetrahedral coordination, with four oxygen atoms surrounding a central Si atomsee 3-D Unit Cell. Thus, SiO2 forms 3-dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms. In contrast, CO2 is a linear molecule. The starkly different structures of the dioxide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silicification
In geology, silicification is a petrification process in which silica-rich fluids seep into the voids of Earth materials, e.g., rocks, wood, bones, shells, and replace the original materials with silica (SiO2). Silica is a naturally existing and abundant compound found in organic and inorganic materials, including Earth's crust and mantle. There are a variety of silicification mechanisms. In silicification of wood, silica permeates into and occupies cracks and voids in wood such as vessels and cell walls. The original organic matter is retained throughout the process and will gradually decay through time. In the silicification of carbonates, silica replaces carbonates by the same volume. Replacement is accomplished through the dissolution of original rock minerals and the precipitation of silica. This leads to a removal of original materials out of the system. Depending on the structures and composition of the original rock, silica might replace only specific mineral components ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium
Potassium is the chemical element with the symbol K (from Neo-Latin ''kalium'') and atomic number19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives. In the periodic table, potassium is one of the alkali metals, all of which have a single valence electron in the outer electron shell, that is easily removed to create an ion with a positive charge – a cation, that combines with anions to form salts. Potassium in nature occurs only in ionic salts. Elemental potassium reacts vigorously with water, generating sufficient heat to ignite hydrogen emitted in the reaction, and burning with a lilac- colored flame. It is found dissolved in sea water (which is 0.04% potassium by weight), and occurs in many minerals such as orthoclase, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorants
A colourant/colour additive (British spelling) or colorant/color additive (American spelling) is a substance that is added or applied in order to change the colour of a material or surface. Colourants can be used for many purposes including printing, painting, and for colouring many types of materials such as foods and plastics. Colourants work by absorbing varying amounts of light at different wavelengths (or frequencies) of its spectrum, transmitting (if translucent) or reflecting the remaining light in straight lines or scattered. Most colourants can be classified as dyes or pigments, or containing some combination of these. Typical dyes are formulated as solutions, while pigments are made up of solid particles suspended and are generally suspended in a vehicle (e.g., linseed oil). The colour a colourant imparts to a substance is mediated by other ingredients it is mixed with such as binders and fillers are added, for example in paints and inks. In addition, some colourants impar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inorganic
In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemistry''. Inorganic compounds comprise most of the Earth's crust, although the compositions of the deep mantle remain active areas of investigation. Some simple carbon compounds are often considered inorganic. Examples include the allotropes of carbon (graphite, diamond, buckminsterfullerene, etc.), carbon monoxide, carbon dioxide, carbides, and the following salts of inorganic anions: carbonates, cyanides, cyanates, and thiocyanates. Many of these are normal parts of mostly organic systems, including organisms; describing a chemical as inorganic does not necessarily mean that it does not occur within living things. History Friedrich Wöhler's conversion of ammonium cyanate into urea in 1828 is often cited as the starting point of modern ...

Kingdom Of Bavaria
The Kingdom of Bavaria (german: Königreich Bayern; ; spelled ''Baiern'' until 1825) was a German state that succeeded the former Electorate of Bavaria in 1805 and continued to exist until 1918. With the unification of Germany into the German Empire in 1871, the kingdom became a federated state of the new empire and was second in size, power, and wealth only to the leading state, the Kingdom of Prussia. The polity's foundation dates back to the ascension of prince-elector Maximilian IV Joseph of the House of Wittelsbach as King of Bavaria in 1805. The crown would go on being held by the Wittelsbachs until the kingdom came to an end in 1918. Most of the border of modern Germany's Free State of Bavaria were established after 1814 with the Treaty of Paris, in which the Kingdom of Bavaria ceded Tyrol and Vorarlberg to the Austrian Empire while receiving Aschaffenburg and Würzburg. In 1918, Bavaria became a republic after the German Revolution, and the kingdom was thus succeeded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
