Teflon layer from facet to facet is eliminated by rubbing with a ground-glass (e.g., fused silica) conditioning plate. No abrasive is used for this operation; it is the roughness of the flat ground-glass plate that abrades the Teflon. A photograph of a Teflon lap and its setup with a workpiece in the holder is shown in fig. 2. This process
