Calamini Urbano srl
Pietra Serena Extraction and Processing
In the 1970s, the Urbano Calamini firm began its activity of extraction of the Pietra Serena of Firenzuola.
At that time, the extraction procedure was limited to the blocks present in the outcrops, where therefore the “uncovering” maneuvers were considerably easier. That Pietra Serena was sold as raw material without further processing. For years the Pietra Serena had been a typical material of the Tuscan area of Firenzuola. To support its processing, Urbano Calamini opened a small sawmill and a laboratory, where he began to work on his own stone blocks extracted from the “Ricavoli” and “Della Guardiola” quarries.
The company is located in Firenzuola, in the historic mining area of Pietra Serena. All the handling and storage activities of the blocks coming from the company owned quarries and other raw and semi-finished materials take place within a large yard. Production and processing activities are carried out in equipped covered areas and inside a workshop that also houses two workstations, designed for the processing of slabs at the blocks handling area. In the outdoor storage area for raw materials, there is also a single-blade frame for sawing and squaring the blocks. The structure is completed by a covered area that houses the administrative and management offices.
Stone Tile: Innovation
Over the years, upon Urbano Calamini’s sons entering the business, the firm had significant growth with a great differentiation in production to cope above all with the growing demand for products in Pietra Serena.
The extraction of the Pietra Serena of Firenzuola takes place within the company quarries and all the raw material is processed along the supply chain.
