I've got a fair sized corral of stones both natural and manufactured. To date, the only stone that was amazingly flat right out of the box oddly enough (since it's a natural stone) was a Tam O' Shanter from Coully. The pencil grid disappeared across the entire surface of that stone in less than 5 passes on the Shapton GDLP! I thought I was seeing things and didn't believe it. The re-grid for good measure proved I wasn't crazy.
So, in my experience, virtually any stone needs lapping prior to use including the Shapton Ceramic on Glass stones.
