My Escher arrived today, and I've lapped it. Yet to try it out.
I was worried at first because water was beading up on the surface. I had asked the seller if it was oil-free but he didn't reply.
Luckily once I started lapping the water started to cover the surface. Do Eschers need soaking? Or maybe it was just glazed?
