Bowed Nero Assoluto

Hi Guys,

Any one like to comment on how 3Cm Slabs (http://www.VerdeUbatuba.com) of Nero Assoluto could be bowed

I wondered how the 1/8" bevel top & bottom gradually turned into a 1/4" bevel on the bottom (with no bevel on top) on the overhang side of an island (http://maplered.com) that came off the CNC.

The slab had a bow of 3/16" side to side but was reasonably flat length ways.

How can 3CM Stone (http://g603.net) bow like this? it can't possibly be polished this way at the plant and (http://maplered.com) must have bowed in shipping or by being subjected to a combination of moisture and (http://maplered.com) heat, or something!

Any ideas gentlemen?
