Corian Lap Problem?

I’m having scratches using a Corian Lap on a Jersey Instruments 8; 3000 to —>8000 polish reveals scratches - cleaned 3000 lap - charged with 5000 using olive oil —>then olive oil on wax & still getting scratches then after lengthy polish until when it stops cutting - charge 5000 and go back to start over with scratches - (cleaned & peeled wax with razor) - repeated this with same results.

Material is a mystery stone - Quartz?

Any feedback with tips on Corian laps would be appreciated?

I found a solution in Tom Herbst encyclopedia and have been polishing this mystery stone with sweet success - mixed 1 part olive oil with 4 parts alcohol and 1 ct. diamond dust - shake and spray works!!
