Sodalith Blue
Die Nahaufnahme der jeweiligen Steinsorte gibt ein relativ getreues Abbild der Kristallstruktur und der Farbstellung (bei Bildplatten nur eingeschränkt) wieder. Bei genauen Farbabstimmungen bitte immer ein Originalmuster des Einrichtungshauses zu Grunde legen.
Petrography
Plutonic rock, stemming from melts with low silicic acid contents, which could not form quartz and no or only little feldspar, is called foyaite. Feldspar was substituted by the so-called foid-minerals (feldspar substitutes), like in this case, the deep blue sodalite. The blue color, from which this stone takes its name, is its rather typical characteristics. However, the color range ranges from white to yellow to red-brown in many different shades. The minerals sodalite and nepheline are chemically instable against acids and salts. This stone is not resistant against acid! Partial solution on the surface and crater forming may occur. Architects and clients have to be informed, especially, when it is a matter of usage in the kitchen or as a washstand in the bathroom. Possibly, rust forming may occur due to a high content of iron minerals.
Petrogenesis
Ursprung waren Kalkablagerungen am Boden eines Urmeeres, die wohl zum großen Teil aus Schalenresten von Organismen bestanden. Diese verfestigten sich rasch zu Kalkstein, der in späterer Zeit unter dem Druck auflagernder Schichten oder bei Gebirgsbildungsprozessen begann, unter Bedingungen der Metamorphose zu kristallinem Marmor zu werden.
