Gold chloride solution % 0.2
Gold Chloride is commonly used in silver staining methods as a toner. After treatment with gold chloride (AuCl3) silver impregnated substances such as reticulum fibers change from brown-black to purple-black.
Toning oxidizes silver ions and the gold chloride is reduced to metallic gold. Metallic gold is more stable than metallic silver and toned sections have a better contrast than untoned sections.
