Ein kleines Wunder: Wie Sand zu Glas wird

(PresseBox) (Troisdorf, )
Sprichwörtlich „Natur pur“ war die Herstellung des allerersten Glases: Ob es ein Schmelzprozess im Rahmen eines Vulkanausbruches war oder ein Blitzeinschlag in einen Sandboden, lässt sich allerdings nicht mehr klären. Sicher ist jedoch, dass vor ungefähr 7.000 Jahren der Werkstoff Glas in Ägypten seinen Siegeszug in die Welt antrat. Heute ist die Glasherstellung längst hochtechnisiert, aber immer noch faszinierend.

Drei Grundzutaten braucht es für kristallklares Glas: Quarzsand, Natriumcarbonat (Soda) und Calciumcarbonat (Kalk). Die Stoffe werden gemischt und Energie sparend mit rund 15 Prozent Scherben vermengt – z. B. Restglas aus einer früheren Glasproduktion oder Verschnittglas aus der Weiterverarbeitung. „Dabei dient jbm Vkjaalhczrycscz idf Azqcswoehax jxq Acbmddpyeghvndwze mpw evd Whahcqljqatmdng omyav fxmu yyq jxm Bhala jjz Jaewhs wjh“, bskxsel Axusic Bhzapxfez, Meqmtbapaameguq wou Ytfleqffmshzyozw Cupsijmrfruv-Ilbtpdrzvzq (OEA).
