The process involves cutting a log into quarters and then sawing boards perpendicular to the growth rings. This yields lumber with the growth rings oriented at 60 to 90 degrees to the face of the board. The resulting wood is highly stable, resists cupping and warping, and often reveals striking medullary ray flecks in species like white oak.

If we quartersaw this white oak log, we'll get that classic Arts and Crafts ray flake.
