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.
Bardiglio is an old denomination for grey-coloured marble from the Carrara area. These are very fine-grained carbonate rocks with an average grain size of 0.5 mm. Enrichments of graphite (generated from organic carbon) cause the in intensity varying grey shade. In the light to dark-grey stria-clouded surfaces appear white veins free from graphite, as well as dark-grey to black structures.
The marble region around Carrara has been generated by metamorphosis of a limestone massif with inclusions of organic components (dead animal and plant remnants). Over the millions of years, the limestone has been re-crystallised to marble. The grey-colouring graphite inclusions have been generated from the organic components in finest and regionally different concentrations.
