The close-up view of each stone type shows a relatively true image of the crystalline structure and the colouring. This is suitable for grained slabs to a limited extend only. In regard to the colour matching, please take an original sample of the stone from your furniture store as a basis.
The structure of this rock is transparent quartz. As it is optically dominated by the black biotite-mica and the noticeable glittering muscovite-mica, it is not noticed. The lively appearance results from different concentrations of the contained minerals and its changing direction orientation.
Quartzite of this type has been generated under very high pressures and tempera-tures, as they are typical in areas of folding up mountain ranges. In this case, the original rock was sandstone, containing a lot of clay. Due to metamorphosis and adjustment of the minerals a completely new rock was generated with essentially better technical characteristics and high decorative qualities.
