In the quest for making tarnish-resistant metal products, I am
reminded of my mother’s brass/bronze flatware called Dirilyte. It
was popular in the 50’s when she was married. We were forever
polishing it to remove the grey/black tarnish until the late 60’s
when she returned it to the factory to be coated with their “Bonded
Protection” process. It is some sort of thin, transparent coating.
Since then, no polishing has been necessary. We use the flatware,
wash in hot soapy water, put in the dishwasher, etc., without any
ill effect. My mother has always said that it is some sort of polymer
coating.
Soooooo, now for the 64 thousand dollar question - what is this
coating? How is it applied? Is it effective in protecting other
metals?
