Use sliding and rotating 8-like motions on slurry and you will have no such problem.

BTW when you are lapping jnats on hard ceramic or cast iron plate you wouldn't have troubles with wearing of the lapping plate so you don't need to use 3 plates or stones.


I have used silicon carbide slurry on glass/ceramics/etc lapping plate a lot of times always checking flatness with toolmaker's straightedge and I have never came accross any issues with flatness.
