Exposed plate held over heated vat of Mercury, the vapors of which converted the silver that had been exposed to soluble form that could be washed away. The remaining silver remains, black in tone, on the plate.

However, solution applied to paper, as opposed to metallic plate.
Primary advantage of this:Produced a paper negative, from which reproductions could more easily be
made.
