Is that a grid line in the corner? Yeah that's the pic I meant... thought it was just a linear artifact in the stone... either way... that does not look like a lapped ark. Like I said, that's what a stone looks like coming off of coarse abrasive powder... not ready for use yet. I'd have charnleys come off 60grit sic looking like that and they'd cut like coarse crystolon until the surface broke in.
New pic looks much better
And yeah trans ark is way under 3.0 sg... its 99.9% or so pure quartz.. which is like 2.7 sg if memory serves...
