Lavorazione Campane

Gennaio 13, 2018 Written by

MARINELLI

Le fasi di lavorazione che portano alla nascita della campana richiedono un lavoro attento e paziente ma principalmente esperienza e passione.

Oggi nella fonderia Marinelli si usano le stesse tecniche ed i materiali dei maestri del Medioevo e del Rinascimento. La tecnologia non ha accelerato il ciclo di lavorazione che può variare da due a molti mesi. Nel 1700 la campana aveva finalmente assunto una forma ben definita, molto simile a quella odierna, tuttavia persisteva spesso la sproporzione fra diametro ed altezza percui continuava a conservare un aspetto affusolato. In seguito fu definita una scala campanaria che indicava proporzioni perfette tra spessore, peso, circonferenza ed altezza, rapportati al timbro sonoro richiesto. La campana può essere considerata un tronco di cono inserito in un cubo; il suo profilo viene disegnato dal compasso non essendovi linee diritte, come riporta anche Diderot nell’ ” Encyclopedie” e questo determina la buona riuscita della campana e del suono.

Preparazione del Modello

Sagoma in legno per campanaSi parte dalla preparazione di una sagoma in legno di noce che corrisponde al profilo della campana. Con essa si disegna una struttura cava di mattoni corrispondente all’interno della campana, L’ANIMA, sulla quale viene distribuito un primo strato di argilla. Sull’anima si sovrappongono alcuni strati di speciali argille fino ad ottenere la FALSA CAMPANA che avrà esattamente lo spessore voluto per la campana di bronzo. Su questa superficie, perfettamente levigata, si applicano fregi ed iscrizioni in cera che dedicano e decorano la campana.

L’ultima fase di formatura consiste nel preparare il MANTELLO ottenuto dalla sovrapposizione di strati di argilla. A modello ultimato viene sollevato il mantello per scoprire la falsa campana che verrà distrutta, il mantello sarà riposizionato sull’anima cosicchè all’interno del modello si sarà creata l’intercapedine nella quale verrà colato il bronzo.

A questo punto Il Modello è pronto per essere collocato nel fosso di colata, ai piedi del forno, per essere interrato. Il modello della campana è bloccato saldamente nella fossa di colata al fine di non subire spostamenti durante la fusione. Il bronzo (78 parti di rame e 22 di stagno) fonde in un grande forno a riverbero, alimentato a legna, alla temperatura di circa 1150°.

    This is not the very first time I came across a blog site that was well worth writing comments on. This distinct piece of writing
    is advantageous to me. I honestly live a lifetime
    of plenty of ways; that is to say that my work functions are distinct.
    I carry out Postpartum Massage Therapy. Furthermore, I buy and sell antiques.

    I'm studying Direct Admin. And, that's merely a handful of activities I carry out.
    At any rate, my idea is, each one of us approaches a topic from a completely unique mindset.
    Just about every single experience we have forms us and each
    of our viewpoint of ourselves and the community all
    around you and me. I presume trying to find some variety of larger sense
    of reality is just where almost everything many of us
    converse regarding leads to. That being said, how can men or
    women afterward communicate? Is it actually possible? I think
    that much of our very own additions to the Internet
    Commons transforms quite a few men and women, possibly.
    For that reason think about that, bloggers and individuals leaving comments.
    Your feedback may possibly benefit a different inividual.
    Or perhaps, remarks can easily accomplish the antipode.
    Plus, everyone, meaning, you, me, actually should
    preferably care to try to benefit other people to
    improve and in no way wither. Thank you for this unique post; I
    am logging this blog together with my additional high-quality weblogs I've come across that I sometimes
    troubled to opine on. Continue to never stop writing!

    Always keep articulating!
