No problem, rkeeb.  You have brought so much information to this site by your diligent search for information so that this thing with RheoMinerals pales in comparison to all you have contributed.  To be honest, I still think of RMI as the old Hectorite and the term RheoMinerals is almost foreign to my mind.  Thanks again, rkeeb, for everything you do here and on TOB.   Okiedo
