Thanks for the link. I was just curious. Kind of academic since I can't just run to HD and buy some.

I'm not sure exactly where we are supposed to go out and find particles in the "0.100 to 0.150 mm" range (as suggested by Dr. Shimek on RC). Seems to me even this dolomite stuff is around 0.200mm? And I remember reading somewhere that he even thought 0.300mm was too large for the majority of the DSB. [img]images/smiles/icon_confused.gif[/img]
