Laboratory Pietra Serena
Optimization and innovation
Following a path focused on the enhancement of Firenzuola’s Pietra Serena and its applications, the company has optimized its internal organization over time, constantly improving its production techniques. The processing of raw materials takes place inside the large laboratory, in the areas equipped for the different types of production. The coordinated supply chain makes it possible to obtain a good variety of standardized products, as well as special customizations in accordance with the functional needs of the customer. The processes are performed with modern automatic machines, thanks to which it is possible to monitor and regulate all the operational phases, allowing the optimization of production in total respect of quality.
Pietra Serena is used for the construction of artefacts, for the restoration of historic centres and architectural elements. All this takes place in complete synergy with the architects responsible for the works, according to a production process that is carried out in line with the most up-to-date and efficient conservation techniques.

Sandstone processing
The manufacturing process takes place after the transport of the blocks inside the laboratory. Sawing is a process through which slabs of various thicknesses can be obtained. This operation is performed using frames with diamond blades.
Most of the slabs in Pietra Serena di Firenzuola are sold in this form, while the remainder is stored again, selected and coded, to then move on to the finishing phase, where the slabs are processed according to the client’s requests.

Thanks to the experience of its master stonemasons, Calamini is also able to carry out the craftsmanship of great value. The handcrafted artefacts are expertly cared for down to the smallest detail, to satisfy every single customer’s need.
The machinery used, which is essential for a good performance of the processing and finishing activities, include single and multi-blade frame saws and modern automatic machines. Finally, the equipment is completed with tools of the prestigious stonecutter tradition, essential for purely manual processing.
