[QUOTE=Loris Medici;827735]Dante I'm not sure if ready-made (designed for S/G printing) gold-thiourea toner is OK. I have always used the toner mentioned here:
There are formulas for gold, platinum, palladium and selenium toners in my article on kallitype at unblinkingeye.com. These toners will work with Vandyke just as well as with kallitype. With gold, platinum and palladium you tone before fixing, but selenium toning should be done after fixing.
