The ones I analyzed all turned out to be oligoclase.  However I'd like 
to know how you can treat feldspar to give it that reddish color.  There 
was something odd-looking about all of it when I compared it to 
Ponderosa material, but I couldn't quite figure out why.

Let me know when you see the release!
