title: Porosity in gold cast against an electroformed gold matrix in an inlay technique.
abstract: The information obtained from the metallographic procedure used in this paper, as compared with techniques of the past, indicates that certain subgroups such as pinhole porosity, microporosity and subsurface porosity require re-evaluation.
