Photographers' Formulary Gold Chloride (Solid, 10g)

This is 10g of solid Gold Chloride from Photographers' Formulary. It is traditionally used as the main component within gold toning baths, and lends a distinctive tonality to finished black and white prints, ranging from warm browns to purples, but most commonly a vivid blue. Gold chloride also adds durability and helps to protect the silver content within a print from degenerating.
