Try a very, very light sanding with 120 grid paper -- just sort of rubbing
to get a few scratches on the surface. Then douse with the cheap rubbing
alcohol from the market. Keep it wet for about 5 minutes. Let it dry,
perhaps
with light heating from below (electric blanket?).

Repeat a few times and you will have pieces with the largest dimension about
10mm.
