Hi all,
I am currently studying Horology at Birmingham City University.
we've been restoring a carriage clock in this project, an whilst doing this I found that the platform had been silvered but was heavily tarnished.
My tutor told us to use cream of tartar in a toothpaste like consistency. Which worked great (see photos)
my question is.............. is there an alternative that you have used to great effect? and pros and cons to using these different substances.

Thanks in advance 20201029_140040.jpg 20201001_131249.jpg

Hi Sam and Welcome to the
For this type of silvering I haven't really found anything better than cream of tartar.
There is electro stripping that could work I havent used that on anything but solid silver articles.
For resilvering them there's a great recent video by Steffen Pahlow on the way I believe these platforms were silvered. Just Silver powder, salt, and cream of tartar.

It is in German but watching the process should at least give an idea.
