The quarry is situated just below the crest of a mountain. Giant slabs delimited by natural fissures are extracted using blasting powder inserted into a series of holes bored into the rock. The giant slabs are then divided into smaller blocks, which are again sub-divided in the workshop using diamond saws, before being manually split into thin sheets by the tile makers (called giuelèe in the local dialect). The tile makers perform precise, rhythmic gestures born of an ancient tradition that encompasses much more than simple mechanical movements. They can predict the quality of the finished product by the sound that the stone emits as it is worked (the clearer and purer the sound, the less fractured the stone). Age-old techniques are still used to handcraft Pioda roofing tiles, which, although they limit the yield, guarantee the quality and exclusivity of the final product.
