Names
The name Gotenrot refers to the Goths , an East Germanic people . In recent years it has been exported under the name Imperial Red or Rosso Imperiale . Other natural stones , for example from India, are also used on the world market with these names .
Rock description and mineral inventory
It is coarse-grained, dark red rock . It consists of 60% orthoclase , 30% quartz and 5% biotite . Plagioclase occurs in only small proportions. Due to its high proportion of potassium feldspar , it is classified as an alkali granite in geology . Since there are several red-colored Swedish commercially available granites, Gothic red can be distinguished by the elongated orthoclase minerals arranged up to 20 mm.
The rock hardly varies in color, only the upper rock layers, which are hardly exported, are lighter due to the beginning weathering processes.
use
Gotenrot was already exported with this name to Germany at the beginning of the 20th century, later to other European countries and overseas.
This natural stone is suitable in construction as a solid stone and for interior fittings, stone monuments and gravestones. Tranås is used in interior and exterior architecture as a decorative element and for stair and floor coverings and facades. It is also used in bathrooms as a washbasin and in kitchens as a worktop , in sculpture and in horticulture for paving and as masonry, especially regionally in Sweden.
Gotenrot facades are located on the main buildings of the Sparkasse Dortmund and Bank Trinkaus in Düsseldorf.
