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. 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 is clear from texts and documents, in this valley in the 12th 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 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 cared for by highly specialized personnel who make use of 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'ardesia (detta anche pietra di Lavagna) è un particolare tipo di roccia metamorfica allotigena, in Italia estratta da tempi remoti prevalentemente in cave della Valle Fontanabuona, in Liguria, del cuneese, in Piemonte e in Valle Camonica, Lombardia. Frutto della sedimentazione progressiva di un limo finissimo dovuto alla frammentazione di rilievi, e caratterizzata da particolare resistenza agli agenti atmosferici, è facilmente divisibile in lastre. In virtù della propria settilità, può essere impiegata in vari segmenti artigianali ed industriali tanto dell'architettura e dell'edilizia (per la realizzazione di tetti, pavimentazioni, gradoni di scale) quanto del design e dell'oggettistica di uso quotidiano. L'ardesia viene usata per la fabbricazione di tavoli da biliardo e lavagne per uso scolastico o domestico. Ma ugualmente importante è il suo impiego anche in campo artistico, in particolare nella scultura di tipo prettamente decorativo, grazie alla vasta gamma di risultati plastici ottenibili.. Di rilievo è stato - ed è tuttora - l'impiego dell'ardesia anche in opere di architettura di ampio respiro (e il suo uso massiccio nell'edilizia della Genova medioevale ne è una testimonianza), come ad esempio i fini portali riccamente lavorati a rilievo. Nella pittura, l'ardesia ha tutt'oggi un impiego pressoché illimitato, come supporto per dipinti ad olio o a tempera. 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.
