3000 years have elapsed since oriental civilization left the first traces of rough bells, although we can rightfully ascribe this discovery to S. Paolino Bishop of Nola, around the Fifth century A.D. Nowadays, as before, the loam casting method remains conceptually the same although, thanks to modern machinery, it has been possible to relieve the man of manual hard work. The basic bell crafting process includes three stages: making an inner mould, a model and an outer clay mould. Once everything is buried in a suitable ground-hole, it will hold the melted bronze and only after a long natural cooling time the bell will be extracted for the cleaning operation. As specified, bells’ production requires the preparation of a clay mould which is engraved. Images, wordings and decorations are cast with the lost wax procedure. This step, artistic more than technical, will give the bell a personal and unique identity. The musical aspect, not less important, concerns the perfect harmonic tuning among many bells (concerts).  In fact every bell plays a specified note, just as a musical instrument, while the timbre is defined either by the quality of the alloy or by the shape of the silhouette. The fascination concerned with this work is certainly unique as it is a merge of technical, artistic and religious components common to the expressions of those distinguished men who marked the way of our civilization. Thought it is in the in the earth, mother of a millenary culture, that the secret of our art work is held.
