Due to its fine crystalline structure, which is hardly coarser than that of the Statuario Venato, the Ordinario is easy to strike. Fine finishes are possible. The crystal structure and its homogeneity make the marble very easy to polish.

PROCESSING
Ordinario can be worked very well by hand using forged point chisels with hammerhead (point chisel, claw chisel, flat chisel, etc.) in combination with an iron scraper. Softer marble can also be worked with forged steel rasps, harder marble with carbide rasps and diamond files. Marble can also be polished by hand to a high lustre. In Italian sculpture workshops, marble is mainly worked with pneumatic tools, which can be used to shape it very precisely. Polishing can also be done by machine.
Sculptures made of Ordinario are particularly suitable for indoor installation. Depending on the nature of the Ordinario, it is also suitable for outdoor sculptures. If necessary, the stone should be treated with an impregnation.
FURTHER INFORMATION
Ordinario is a white-grey marble with graphite enrichments, which has been formed over millions of years through metamorphosis from organic inclusions that run through the rock in the form of grey veins, speckles and clouds. It has a grain size of approx. 0.5 mm. Marble is a metamorphic rock that is around 140 million years old.
Ordinario is a very common type of marble and, like Statuario Venato, is quarried in the Apuan Alps near Carrara. Marble was formed 140 million years ago by metamorphosis from limestone with organic inclusions (animal and plant remains). Pressure and high temperatures crystallised the limestone into marble in deeper layers of the earth's crust over millions of years.
Stone is a natural product. We endeavour to reproduce the appearance of our sculpture stones as accurately as possible in the illustrations so that the character of the stone can be recognised. Ultimately, each stone is unique and the appearance may differ from the illustration.
