Yes Ed,
 
As Ryan explained, thin-sections must be exactly 30 microns thick, not 29
or 31, and from edge to edge, not just here and there.
If you don't have the specialized and very expensive equipment you will
waste a lot of material and a great deal of time.
May I suggest buying those thin-sections ready made, by the world expert in
thin-sections?
 
And yes, I do have the largest selection.
Should this be considered an Ad? or public information? ;-)

Hi Ed,
Thin sections are a bunch of work and have to be withing pretty
strict parameters to let light through correctly. Although I've never
made one myself before, I have friends whom have had to make hundreds
for their masters/PhD projects and its pain, unless you like grinding,
glueing, grinding. When done correctly, and with polarized light, the
results (depending on the minerals) can be absolutely astounding
natural work of art.

Here's a link I came across on how to make one.

good luck!

If you don't feel you're up to the task of making them, you can send
rock/meteorite samples to be made for you, but of course its money,
and the wait can be pretty long (months) to get them back.
