The Pietra Serena of Firenzuola in a Nutshell

Extracted from the Urbano Calamini’s quarries, the Pietra Serena of Firenzuola is the material that embodies and enhances the expression of a great cultural and architectural heritage.
As a matter of fact, thanks to our processing and finishing methods, today the Pietra Serena of Firenzuola has gained a new aesthetic value. This natural sandstone has always been considered as a “local stone”, since it was very common in the local rural architectural landscape.
By using Scalpello, Subbia and Martellina the stonemasons accurately chiselled amazing works of art. The Pietra Serena of Firenzuola reached its maximum architectural value when it crossed local territorial boundaries and reached new and more advanced applicative concepts in the various fields, from architecture to art.
The reinterpretation of the fundamental qualities of the “Pietra Dura di Firenzuola”, place this material as a part of a renewal process. In fact, it has acquired a greater world value thanks to its innovative application and use both in the structural and decorative areas.

The Chemical Composition of the Pietra Serena

The Pietra Serena is a sandstone also known as sedimentary stone. This limestone formation was formed by the cementation of sand coming from different geologic ages, due to the corrosive action of local rivers, seas and lakes.
Calcium carbonate is the binder in the form of calcite, aragonite or, less commonly, iron oxide or silica. This natural stone is, in fact, one of the few stones to maintain a chromatic consistency given the purity of the material.
