<p>The object has an upper surface with a grinded facet (1), which is in the form of plants or animals e.g. mouse, where the facet has concave or convex curved areas (5, 6). The facet with the curved areas is a part of a surface that occurs with a variable curve by a parallel movement of even form ends (3) longitudinal to a guiding curve (2). The surface is formed under simultaneous rotation of the ends around an axis runs in a direction of the curve, where the object is made of glass.</p> |
