Abstract
Carving of perspective designs in transparent objects with ultrasonic abrasive slurry machining is obtained by using at least two tools each having a different configuration at the working surface and sequentially carving each tool in the object on a surface thereof in partially overlapping relation to each other at different depths. Means are provided wherein the object is sequentially advanced from tool to tool to be multiply carved with each carving being of a different depth than the prior carving to obliterate same and to present to the viewer a perspective carving when viewed from the opposite surface than the surface carved.
