<p>Apparatus and methods for shaping a surface of a material are described. An example method comprises providing one or more shaping elements, softening the material, and urging the one or more shaping elements against the material so as to form one or more grooves in the material. The configuration of shaping elements can be adjusted to provide a desired pattern of grooves in the surface. The method can be applied to inorganic crystals in a high temperature plastic state, avoiding the problems associated with conventional sawing techniques.</p> |
