Soil concretions were impregnated with two types of plastic resins to compare the quality of polish and surface relief, after mounting and polishing, for electron microprobe analysis. Soft or hard porous concretions impregnated with “Castaglas,” a cold‐setting epoxy resin, resulted in loss of surface material due to plucking during polishing. Impregnating the same type concretions, under vacuum, with a temperature‐dependent methacrolate resin, resulted in little or no loss by plucking, and good to excellent polished surfaces.
