MOHS is the standard scale of hardness for minerals 1-10, with 10 being the MOHS of diamond. We also use the broad terms Hard and Soft for simplicity. Read more here.
A fine-grained, white to light beige marble of the Jurassic period (Lias) with yellowish-brown-grey decoration.
Also available in standard tile formats.
Petrology:A very fine-grained white marble with striking arabesques which vary grey to brownish-yellowish in colour. These differences in colour and pattern occur depending on the quarry it was mined. The name Calacatta originates from the Italian language describing the texture for marble with large-scaly structures. This term has become established for a number of deposits and varieties.
Petrogenesis: The Apuani marble area of the region of Carrara-Massa-Pietrasanta was generated during the Jurassic formation by a metamorphosis process covering a large region. Limestone complexes with different contents of organic contents and different quantities of clay minerals were re-crystallised to marble under high pressure and temperatures caused by folding-up of the Apennin mountain range. The residual clay, participating in decorating the arabesques, can be coloured lightly reddish or yellowish-brownish due to hematite or limonite enrichment.
