Frictional anisotropy is observed with crystallographic planes and sliding orientations of ice. Availing this phenomenon, a high speed skating rink was made by use of a large-single crystal ice and its lowest frictional plane. Moreover, new rinks will be made using anisotropy in plastic deformation of ice. The lower friction of curling rinks and oriented snow grains at surface came in sight. These high speed rinks were derived from the basis adhesion theory, and self-inconsistency in frictional melting theory as classical frictional mechanism was revealed.
