  What we have here is a Ying and Yang, white and black, yes an no, north
and south, and live or die. You mentioned that it is not possible to accuratly
measure the incident angle of of reflection which prompted me to reply as I did.
Now you are back on the subject of measuring the ior values of non refractive
materials again. Let's pick one subject, discuss it, then move to the next in
turn so we both know what the heck we are replying to.

P.S. I checked a list a couple of hours ago that listed the ior values of over
170 different materials and not one of those listed was a common metal type.
All were related in some way to crystaline structures and materials. i.e.
quartz, glass, silicon carbide, salt, etc...
