A film showing the crystallisation of gold layers.
This 1950’s film was made by the Metal Physics Group of Tube Investments Research Laboratories, Hinxton Hall, Cambridge. It shows the growth of gold layers formed inside an electron microscope. The demonstration uses both a thin carbon substrate and a thin flake of molybdenite alternately to grow the gold layers, and at times shows a 20x increase in actual growth rate to get a more visual effect.
During two sequences, recrystallization occurs during growth and black and white islands are shown in different orientations (double positioning).
