These developments are creating markets for antimicrobial copper and copper alloys in interior architecture. To meet the design needs for building surfaces, structures, fixtures, and components, antimicrobial copper-based products are available in a wide range of colors, finishes, and mechanical properties.
Copper belfry of St. Laurentius church, Bad Neuenahr-Ahrweiler Metals used for architectural purposes include lead, for water pipes, roofing, and windows; tin, formed into tinplate; zinc, copper and aluminium, in a range of applications including roofing and decoration; and iron, which has structural and other uses in the form of cast iron or wrought iron, or made into steel.
A copper disc (99.95% pure) made by continuous casting; etched to reveal crystallites Copper just above its melting point keeps its pink luster color when enough light outshines the orange incandescence color. Copper, silver, and gold are in group 11 of the periodic table; these three metals have one s-orbital electron on top of a filled d ...
The Statue of Liberty gets its famous green color from the natural patina formed on its copper surface. The green patina that forms naturally on copper and bronze, sometimes called verdigris , usually consists of varying mixtures of copper chlorides , sulfides , sulfates , and carbonates , depending upon environmental conditions such as sulfur ...
Lead and copper have played a significant role in architecture for thousands of years (see: copper in architecture). Lead was one of the first and easiest metals to smelt and with a low melting point, it could be easily formed to be watertight. As a by-product of silver smelting, in Roman times it was readily available and relatively cheap. [1]
The optical properties (color, intensity) of minerals such as azurite and malachite are characteristic of copper(II). Many coordination complexes of copper(II) exhibit similar colors. According to crystal field theory, the color results from low energy d-d transitions associated with the d 9 metal center. [12] [13]

Example of a copper alloy object: a Neo-Sumerian "Foundation Nail" of Gudea, circa 2100 BC, made in the lost-wax cast method, overall: 17.5 x 4.5 x 7.3 cm, probably from modern-day Iraq, now in the Cleveland Museum of Art (Cleveland, Ohio, USA) Copper alloys are metal alloys that have copper as their principal component.
