The equipment and technique for the production of optical surfaces on proustite with flatnesses approximately Lambda10 He and residual scratches approximately 5 nanometers peak-to-valley are described. The relative merits of soft metal and wax laps are examined. It is concluded that proustite and other similar soft crystals can be worked quickly and accurately by these techniques. Author
