soil aggregates


Dear Histonetters,

A colleague is wanting to see inside soil aggregates of varying 
thicknesses, up to several hundred microns. I was able to make paraffin 
sections, 20 microns, by soaking the samples in paraffin for many 
hours.  No solvents allowed.  A researcher at NASA gets 1 micron sections 
from his dust particles in sulfur. We have no idea how he does it.
Thinner is better. Any suggestions out there? Do any bone grinders have any 
ideas? Do you know of anybody else we can ask?
Please include Dawit in your responses. Dawit, do you have anything to add?

Thank you very much.
Mary Lou
