I am wanting to gold tone Vandyke prints. I can buy Moersch gold toner (1 litre ) for £78 ( $105). I am a little confused about how to make it yourself, at least i'm confused about buying gold chloride. Googling it, I can buy Gold (III) chloride 500mg for £127 ( $171). My question is: Is it the gold chloride I need in powder form (AuCl3) and at that price, is it significantly more economical to make it myself rather than buy the ready made Moersch formula? Cheers.
