Abstract
A protective coating is applied to a bell body composed of bronze by simply dip-coating the bell with an outer layer of zinc. The process is carried out by immersing the bell body in a hot aqueous solution containing sodium hydroxide and powdered free zinc. After the bell is removed from the coating solution it is rinsed and then polished. The coating protects the bell from environmental contaminants without changing the frequency or musical quality of the bell and therefore may be used equally with newly manufactured or refurbished bells.
