Recrystallization was identified by the reformation of white crystals within a few seconds of cooling. Once cool, the two sheets were separated, and the two layers of the mixture obtained were floated on to a water surface. The benzoic acid dissolved in the water and the remaining wax specimens were picked up on TEM grids. This procedure resulted in paraffin crystals supported on the carbon film of the TEM grid, giving chains lying flat on the TEM grid support film surface.
