Elegant Brown anticato
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 rock consists of an extremely fine grain from quartz, almost undetectable to the naked eye, and also some feldspar and dark rock fractures. The finely dispersed iron oxide limonite causes the brown shade. The fine layering is irregular and reminiscent of wood grain and at some locations is interrupted by quartz streaks. Also crossing layers appear fairly often, indicating irregular depositing conditions.
Silt stones can be described as extremely fine-grained sandstone. Just like sandstone, their origin is weathering of quartz-rich rock such as granite or gneiss. Rivers transported the eroded material to the sea where enormous layers were deposited in some locations. The structure was compacted by the pressure from the deposited sediments; in addition, cementing of the particles occurred by binding quartz.
