Hi Kent (and John, and list),
Yes, I do have a MS in press at Am Min (see attached proof) that talks about how to make grain mounts. That’s what John was referring to.
However, I don’t have much information on how to make oriented sections. It’s straightforward to make mounts of quartz that are perpendicular to c and tourmaline that are elongate parallel to c. Those instructions are pretty clear in the paper (I think).
But I didn’t have a simple method for what you’re talking about – Bxa, Bxo, OA, etc. So that’s not part of the paper.
I agree it would be helpful if someone could figure out how to do this. Without being too expensive.
Best,
Matt
Note: While I may send email outside of regular business hours, I do not expect the same from others.

John Brady tipped me off that you have some info on how to make oriented grain mounts. We don't get American Mineralogist anymore, but if there was a way to send some instructions or tips, I would be very appreciative.

Hi Kent,
Matt Kohn (mattkohn@boisestate.edu mailto:mattkohn@boisestate.edu) has an article in press in American Mineralogist that has good instructions of how to make some very good grain mounts that might meet your need. Matt will probably respond to your post, but if not you should contact him.
Good wishes,
John

All,
Quite a few of our oriented mineral grain mounts are either showing their age (e.g., cracked epoxy or maybe Canada balsam, broken glass slides, etc.) or otherwise low in quality (e.g., having lots of cracks or veins or inclusions and yielding cloudy interference figures, not well-centered figures, etc.). I could go through a few iterations of cutting up some stuff from our mineral specimens, guessing at or doing rough measurements to find the orientations for various figures (Bxa, OA, etc.), sending them off for thin-sections....but before I do that, perhaps I should ask if anyone makes these anymore? If so, I'll bet they are expensive.
