The Brothers DEMARTINI Slate Srl was founded in 1954 by brothers Giovanni, Antonio, Auro and Giambattista. Since then it has always carried out slate mining and processing activities. Tradition, experience and modern production technologies applied to the processing of the "blackboard" make Fratelli DEMARTINI Ardesia Srl a leader in the sector. Its products are now marketed internationally. In Val Fontanabuona, (Genoa), slate is also called "the sleeping bread", and the expression gives an idea of its importance for the local economy. The extraction of slate began in Italy, as evidenced by texts and documents, in this valley in the twelfth century. The Fontanabuona slate was immediately better, also in terms of quality, compared to that of the neighboring valleys. The start of a systematic mining activity in Fontanabuona began in the second half of the last century. Currently, the annual transformation of the raw product extracted in the Fontanabuona is around 800,000 tons. The extraction of slate mostly takes place in underground quarries. The search for a quarry takes place through geological surveys and inspections, made on the basis of external and internal references. Despite the investigations and surveys, it may happen to find poor or modestly sized fields, such as not to compensate the investments used for the operation. The cultivation of the quarry is handled by highly specialized personnel who use very special equipment (such as the rock machine, designed by Ligurian quarrymen), with which he detaches the precious blocks from the vein that is placed between the layers of sandstone L ' slate (also known as stone Blackboard ) is a particular type of metamorphic rock allotigena, in Italy predominantly extracted from ancient times in quarries of the Fontanabuona Valley, in Liguria , the Cuneo, in Piedmont and in Vallecamonica, Lombardy. The result of the progressive sedimentation of a very fine silt due to the fragmentation of reliefs, and characterized by particular resistance to atmospheric agents, it is easily divisible into slabs. By virtue of its septility, it can be used in various artisan and industrial segments both in architecture and construction (for the construction of roofs, floors, steps of stairs) as well as in design and objects for everyday use. Slate is used to make pool tables and blackboards for school or home use. But equally important is its use also in the arts , particularly in the sculpture of type purely decorative , with a broad range of plastic results obtained .. Of note was - and still is - even the use of slate in the works wide-ranging architecture (and its massive use in medieval Genoa construction is a testament to this), such as the fine portals richly worked in relief. In painting, slate still has an almost unlimited use today, as a support for oil or tempera paintings. In the world, important quarries for the extraction of slate are located in Portugal, Wales and Vermont. A particular type of slate has also been found in areas of the Arctic. It is believed that this type of stone was also worked by the Inuit people, who used it to make rudimentary knives intended, among other things, for the skinning of animals.
