For those interested in printing with the iron processes I have a new article at http://unblinkingeye.com/Articles/GTV/gtv.html
People have been making gold toned vandykes and kallitypes for a long time but my article describes specific working procedures designed to optimize Dmax (or refletive shadow density) and to tone to completion in order to replace as much of the silver image as possible with gold metal. If worked correctly this printing method should give prints that are comprised to a very high percentage of gold metal, giving them high image permanence.
