Re: [ATM] Tile tool x diamond pellets

["Bob May" <bobmay@nethere.com>]

Diamond dust is about that, just like glass dust.  It is graded to size
(should be at least) and is used just like SiC and other grit for the
purposes of grinding stuff although it is a bit more expensive.
The finer grits are more useful for grinding if you are careful with keeping
the tool from binding to the mirror but otherwise, it is just something
fancy to grind with.
Better to use the more coarse grits with copper tools to do trepanning and
coring than on the surface of the mirror as it will embed itself into the
copper and be useful for a lot longer time.
I don't know if you can really seperate the diamonds out from the glass once
they get mixed as I'd suspect that they'd have about the same weight per
volume and thus will settle out at about the same rate, making the settling
process not actually seperate the two from each other.
