Cold mounting or embedding is when a resin is mixed with a hardener (or accelerator) to provide the mounting compound, and then the polymerization process take place to form the block. In some cases, this process gives-off heat. However this heat generation can be controlled by the use of ice or cool air blow setting. Cold mounting compounds are preferred for specimens that are sensitive to the heat or pressure, which applies during the hot mounting process. There are three types of cold mounting:

Epoxy Systems - Epoxies have the lowest shrinkage of all cold mounting resins. The curing time is relatively long, but the adhesion to most materials is excellent. They are also used for vacuum impregnation. The hardened epoxy is duroplastic and not affected by moderate heat or chemicals.
