Re: [ATM] Tile tool x diamond pellets

[Guy Brandenburg <gfbrandenburg@yahoo.com>]

I have been given a little bag of something labeled
'Diamond Dust'. I don't have any idea what it really
is. I looked at it under a microscope, and it looks
like little bitty flakes, not
hexagonal-star-snowflakes, but little trapezoids and
stuff; they tended to be long. Perfectly clear and
transparent, whitish looking, sharp-ish corners. I
havent' tried grinding anything with them yet, so I
don't have any idea how hard they are.

Anybody want to venture a guess as to what they might
perhaps be?
