I worked at Greenfild Village in Dearborn Michigan for awhile as a
silversmith and pewtersmith. We slush cast bells from pewter that
we would buy from C.R. Hill in Berkly MI. The mold was a two piece
steel mold. The clapper wire hanger would be inserted into the mold
then pour the pewter in and immediatly pour it out. The longer we
would wait to pour it out the higher the tone of the bell. The
walls of the bell would thicken and the inside of the bell become
smaller causing shorter sound waves when rung. The clappers them
selves were cast in a modified fishing sinker mold.
This metal was very soft and did make a delightful sound. Many bell
collectors from around the world own bells we made there. Mick
