Church bells

The fidelity to the origins is, in the fusion of a bell, an unquestionable prerogative of the firm producing it. The process of working has remained unchanged and still entrusted to clever craftsmen, who carry out it as it was a rite..

  It lets us create single bells and perfect chimes for the tune and the armony in order of a sixteenth of tone. The first operation is the construction of a core made by clay bricks, that is covered by a layer of chalk, called false bell and which is its interior section. On its surface, very smooth, is applied the wax, on which are engraved the explanations, the inscriptions etc.
The surface is covered by a further layer of clay that is the coat or the jacket of the bell. Finally the cooking is carried out, called lost wax cooking, burning charlcoal inside the core; after melting the wax the negative inscriptions will remain stamped on the jacket, which can be lifted and put on the brick core after destroying the false bell.

In the hollow space formed will be poured melted bronze (tapping temperature 1150/1200 °C). The metal is filtered by special thin baked clay filters, that have been conceived to obtain jets of quality. Some of the most important requisites of the filters are the mechanical capacity to the vantage of security and the filtering honeycomb structure which offers a great filtering power.
According to the low of mechanics of fluids, the melted metal, pressed in small size lights of transit falls in a whirling motion favouring the separation of solid particles, which becouse of attraction will stick to the interior surface of the transit and will not clog up the original section.
The most suitable location to protect the metal clean from contaminations is at the entrance of the shape.


The tonality is already given in the phase of planning, in the drawing of the shape, and it is given by a mathematical ratio between the inner volume and the diameter of mouth, by revision and research. Merolla aims at the safeguard of all the ancient come to our days by the most beautiful instrument man has ever carried out.
