SIM – Plate 25
Plate 25, Fig. 46, 1% Gold chloride and 1% Silver nitrate, equal quantities: the result is a pleasing picture, clear in colour, not especially rich in forms. The borderline, describing a wide curve, is intersected with tiny waves of purple-mauve. Underneath spreads a broad light yellow band. Most of the gold activity is visible’ in the more richly coloured lower part.
