Mr. Stefero,

I checked with a Civil Engineering Professor (at the University of Nebraska) about mesh size. According to him, the smallest mesh size used in his lab is #250. At this size water will not flow through the mesh unless forced (surface tension). The smallest size that he has seen is #325 which is used for sifting powdered cement as well as in the cosmetics industry. Now if you have ever opened a sack of powdered cement it becomes apparent that particles from a #1000 mesh (approx. 1 micron I believe) would become airborne at the slightest motion. He further stated that he thought it was mechanically impossible to grind anything down to that particle size (including clay) but that he couldn't unconditionally say that it could not be done. According to him, it would have to be some process that he had never seen. In other words, he confirms your suspicions about the #1000 mesh. It is extremely unlikely that milling to this size would work at a large scale according to what is presently known by this Professor.

As far as Dr. Johnson, Ray Smith, and Dr. Groves are concerned, Kim or Jerard would probably have the best inside information. I think Dr. Groves is working for CHIP if I remember correctly. Which brings up another question. Why haven't Kim and Jerard been posting lately? There must be a reason. I think it has something to do with not letting the cat out of the bag.
