The of use this material goes back to the days when fractography was done by TEM because SEM was not commercially available, There is, therefore, some very old literature on how to use the material, but since most of it is art, anyway, most current authors assume that the reader is generally familiar with the technique.

There are actually two purposes in using this material. Even for relatively small samples, it may be necessary to remove corrosion products in a nondestructive manner. In my opinion the best way to do this is to use acetone-softened cellulose acetate, which will remove the corrosion product but leave what is left of the metal.
