Application of a mixture of glycol polyethylenes for the preparation of microcorrosion casts--an observation.

Preparation of microcorrosion casts that can be used for observation in SEM is a laborious, time-consuming procedure. The authors paid particular attention to the process of dissection of the microcorrosion casts. This prompted the authors to reconstruct the plastic mass, produced by the firm Gurr (Great Britain) in the 1970s, which was used by them in previous research to immerse the cast in order to minimise the damage. By using easily obtainable polyethylene glycols, characterised by different physical and chemical features, in order to obtain smooth surface of the section, a low-toxic mixture was composed, which protected the microcorrosion casts sufficiently and did not interfere with the physical and chemical properties of the cast.
