.... If minor amounts of heat will alter the microstructure, the lowest exotherm cold-mounting resins must be employed. Compression molding mounting will damage thin, fragile, or friable specimens. Shrinkage stresses can be high enough to pull a protective plating from the sample. Another factor to consider...

... to mounting a sample for sectioning. Less material on the section face results in a shorter sectioning time. Encapsulated (also called “potted”) sample sections are done with the sample encased in some type of material, usually a two-part cold-casting epoxy. The sample is placed in a mold and the mixed...
