Environment & sustainability<\/p>\n

Care in our craft.
\nAnd in our materials.<\/h1>\n

At our foundry in B\u00e4rau, we remelt suitable bronze offcuts and recondition moulding sand for reuse. We also aim to use energy and materials sparingly when melting and packing.<\/p>\n

How we reuse materials \u2193<\/a>Discover our foundry & craftsmanship \u2197<\/a><\/div>\n<\/div>\n

\n

Knowing our materials<\/p>\n

Bronze remains
\na valuable raw material.<\/h2>\n<\/div>\n

The composition of bronze is crucial to a bell\u2019s sound and quality.<\/p>\n<\/div>\n

\n
\n

01 \/ FROM OUR OWN PRODUCTION<\/p>\n

Back into the furnace<\/h3>\n

Casting and finishing produce pouring cups, channels and shavings. We collect suitable bronze offcuts from our own production and melt them down again. Their origin and alloy composition are known.<\/p>\n

The material stays in the foundry\u2019s production cycle and is used for more bells.<\/p>\n<\/article>\n

\n

02 \/ SPECIALIST REPROCESSING<\/p>\n

Recycling old bronze properly<\/h3>\n

Old bells and bronze of unknown composition are sent on for specialist reprocessing.<\/p>\n<\/article>\n<\/div>\n

Reusing moulding sand<\/p>\n

A new mould.
\nWith reconditioned sand.<\/h2>\n<\/div>\n
\n

Every bell needs its own sand mould. After casting, the mould is opened and the bell freed from the sand. The moulding sand is then reconditioned.<\/p>\n

Some sand is lost due to the high temperatures. This portion is replaced; the reusable sand is used again. Its composition and careful preparation also shape the surface of our Berger bells.<\/p>\n

\"Molten
A look inside the melting furnace at our foundry.<\/figcaption><\/figure>\n
\n

Using energy carefully<\/p>\n

Planning each
\nmelting operation.<\/h2>\n

An electric induction melting furnace was introduced at the Berger bell foundry in 1992. The amount of bronze required is calculated for each casting.<\/p>\n

Where the production schedule allows, several melts follow one another, making use of the heat already in the furnace.<\/p>\n<\/div>\n<\/section>\n

\n
\n

The right strap<\/p>\n

Choose carefully.
\nEnjoy it for years.<\/h2>\n<\/div>\n
\n

We mainly use vegetable-tanned leather for our bell straps. We do not use badger-hair trims or wild-animal furs.<\/p>\n

If you already have a suitable strap, bring it along when you visit us. Together, we can check whether its size and attachment are suitable for your cowbell or steel bell.<\/p>\n

\n
\n

Carefully packed<\/p>\n

Well protected
\non the way to you.<\/h2>\n

We use recycled cardboard and paper for packaging. They protect the bell in transit and can be separated for paper and cardboard recycling after unpacking.<\/p>\n<\/div>\n
