Nichtsdestoweniger beginnt die Qualitätskontrolle mit dem Beginn einer potentiellen Geschäftsbeziehung. Wie läuft das bei uns in der Regel ab: Wir setzen größten Wert […]

Die sogenannte Mohs Härteskala ist eine Skala von 1 bis 10, wobei Steine mit höherem Härtegrad jene mit niedrigerem kratzen und ritzen können. Es ist also eine relative, keine […]
