Strings and sealing wax, and other fancy stuph

[David M. Porritt]

Well I finished High School Chemistry 50 years ago now but my recollection
is that iron or steel plated with tin won't rust.  However, if the tin is
scrapped off the iron it will rust worse than if it had not been plated
because of the ion left there.  Scrape some tin from a tin can and see how
quickly it rusts.  Zink on the other hand protects the iron even after it's
been scrapped off, again because of the effect of the ion left.  Can't use
that with cans for food though as the Zink would contaminate the food.  Yes,
that is 50 year old chemistry but I think those elements still have pretty
much the same properties!

I think I saw it in a Fletcher & Newman catalogue, I had, back in the 70's.

I just looked up their catalogue, on line, and they have a Roslau Red, that
is plated.

It doesn't mention the tropics, and that is where I thought I got the idea,
in their old catalogue.

 

If not to resist rust, why have the plated wire?

My understanding is that the tinned wire was mainly for 'tropicalizing'
pianos.

It would definitely be more rust resistant.

If there are "tropicalized" rust resistant wire out there, they haven't
shown up in any of the pianos in Hawaii. Most of the ones I am tuning have
rusty strings, some worse than others.
