Ever wonder how those gigantic bells at the tops of cathedrals and town halls in Europe are made? A visit to the Bell Museum and Grassmayr Bell Foundry in the middle of Innsbruck, Austria, can help to answer that question.
In early times, when a town produced a bell it was a momentous occasion in which the whole community would participate.
Bells intended to be rung are usually made by casting bell metal of copper and bronze and are of a size appropriate for the pitch the bell is intended to produce.
Fine tuning of metal bells is achieved on a lathe where a precise amount of material is removed from the inside of the bell in order to produce a true tone with correct harmonics.
