My name is Robare M. Novou. I'm a sign artist / gilder. I have be researching liquid gilding (gold chloride) for the past 20 years.
I have sucsessfully and safely produced gold chloride from solid gold, on my work bench here in my shop without the fear of breathing dangerous fumes and without the aid of exhaust vents. This is a simple setup..involving 3 flasks and a small amount of chemicals and a few grams of 999.9 gold.
I have written a book detailing formulas and procedures for producing gold chloride for application in gilding.
From what I have read and seen this may be the answer that some of you are seeking for successfully toning photographs with gold chloride. And might I add, at substancial $avings.
