Francia Rosso

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.

Petrography

The limestone consists by over 90% of the mineral lime spar, which is impregnated with very fine distributed iron oxide (hematite). Only as an exception, pure white, almost transparent lime spar is deposited and this creates a significant contrast. 

Petrogenesis

Limestone is - despite participation of almost only one mineral - the most multiplex rock regarding colour and structure. In this case, the lime deposits occurred at the bottom of a primeval sea in Devonian; partially by chemical precipitation and partially shells of micro-organisms containing lime. Occasionally, also larger fossils can be detected.
