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.
Quartz is the main mineral. Differing from the sandstone, the quartz granules are intensively interlocked with each other, giving it a high strength, high hardness and low porosity. The light violet shade is due to slight contents of the iron oxide hematite.
The original rocks are sandstone. These have changed during the folding up period of a high mountain under high pressure and temperature into dense, possible to polish, extremely wear and acid resistant quartzite.
