Now I'm questioning if they are the same,
1. Color - smaller is clearly white, while the big one is really yellow. Age?
2. Slurry - small one produces what seemed more of a green ( I'm sure the sandpaper played a role as to the color but should have been the same)
3. Time to lap - the small one lapped real quick, seemed softer.

When it comes to Arkansas stones, color varies by quite a bit. Not all soft stones are white, they can also be yellow, green, pink, grey/blue, black etc. So there's nothing saying that either the stone or their slurry should be a similar color.

As far as time to lap, there are variables. Smaller stone has less surface area to displace force, so it's easy to exert greater pressure per square inch on it. If the small one happened to be closer to dead flat than the larger of course it would take less time. And 3-4 hours with sandpaper on a rock pretty much screams Arkansas stone to me, I've yet to find a natural hone that matches them in hardness.
