SIM – Plate 29b
Plate 29, Fig. 55, 1% Gold chloride and 1% Iron sulphate, equal quantities mixed: This picture is vividly coloured. In the lower part we notice various delicately formed wavy lines in rhythmical arrangement. The colours, due to the activity of gold, are carried right up to the top and only a narrow band bears witness to the presence of Iron sulphate. Still, we would not classify this experiment as of outstanding value.
