Fwd: Re: [ATM] CeO micron size -- figuring

["Matthew L. Brown" <mlbrown@everstrive.com>]

I use the WB CeO in the following manner:

   First I eat a tall jar of olives -- to get the jar.  After washing it 
carefully (I put it thru the dishwasher, then rinse after with hot water), 
I fill it 3/4 full with filtered tap water (an ordinary sink filter from 
the hardware store) and add about a tablespoon (15ml) of the CeO and shake 
vigorously.  I wait 5 minutes for it to settle mostly, and pour off the top 
half into another jar (more olives, yum).  I let that settle a week or so 
and pour off most of the water and use that for figuring.  The coarser 
stuff in the bottom of the original jar I use for initial polishing.  I get 
the occasional sleeks from the coarser stuff, but that (almost) always goes 
away during figuring.

I keep a 5 gallon (20L) bucket for rinse water.  That I let settle for a 
week or so and always dip the mirror into the top for rinsing between 
sessions.  Because I tend to do one figuring session per night, it gets an 
entire day to settle between sessions.

Oh, and once I determine that I'm on the final figuring path (e.g. all the 
zones and holes and hills are gone and I'm converging onto the final 
parabola) I switch to rouge, which goes slower and gives me a nicer final 
finish.
