Granite thin section
Granite thin section
Messing around with my new 3.2 objective a little bit
Still taking pictures through my eyepiece, looks much better in person.
This thin section is actually very thick, it was one of the first ones I made in school and is absolutely not made well enough for research but thin sections always seem to be nice to look at!

Re: Granite thin section
looking good with your new scope! thanks for posting.
made me wonder how it would look with a regular compound microscope with inexpensive polarizing film adaption.

Nice image jb89!
As long as the analyzer is optically clear the quality should be good.geo_man wrote:made me wonder how it would look with a regular compound microscope with inexpensive polarizing film adaption.

Re: Granite thin section
Thanks!
In one of my field books there are instructions for making a DIY/portable polarizing microscope with a hand lens and polarizing film.
It's just generally not useful to use a polarizing scope on hand sample(for rocks, I have no idea about biology) so I have never bothered.

Re: Granite thin section
Curious, JB89, how long it takes to make a thin section? In hearing the process described, it sounded like an hour or two (or more, maybe a lot more) of work unless some sort of automated equipment was available.

PeteM,
My first one took many many hours, I broke a few slides and had to start all over more times than I'd like to admit.
With just the bare essentials it depends greatly on the general hardness of your sample, I had a jasper conglomerate that took me nearly 4 hours of hand griding.
A thin section machine and hot plate help quite a bit time wise, with them and some experience I think you could probably average close to 45 minutes per slide or less.

JB -- thank you for the insight.
