I love the name "Elutriator. "

think of panning for gold. Peter describes the process well. The only stuff you will really want to keep is the coarse stuff. The stuff coated with silicates gets really slippery. I suppose in gold you just turn needy.

Interestingly, Schott Optical or Steuben ( I forget which) at one point was doing blood tests on employees who were grinding lead glasses. The testing revealed elevated lead levels in those employees. I don't know whether that was from breathing the mist around the machines or from skin absorption.
All the big grinders from Steuben went to the dump and were never put up for sale because of lead concerns.
Where are we going and why am I in this basket?
