Hi all and even Bev,
Assume that you polish a metal, in my case five 9s Ag. Polishes have at
least two purposes. Grind the metal to get a certain level of brightness (we
polish to Ra 30 nanometers). And leave a thin coating that protects the
metal. Now, in our case, what is left is so thin, that you can't observe the
'coating'. Presumably because it's an organic compound of some sort, and
also because it's transparent for our eye's wavelength. Now comes the
question: has anyone out there ever investigated such a 'wax' and
determined the thickness, and if so, what kind of equipment was used?
That's why I more or less directed the q to Bev...
Inge
