MY CLADDING PROCESS,
My plates are commercially made .999 fine silver diffusion bonded (clad) to copper.
The silver thickness is 0.001 clad to 0.019 copper for a total thickness of 0.020. By 19th century standards these would have a "20" hallmark. Twice as much silver as the more common "40" plate.
they come with a mill finish which I bring to a mirror finish by hand. The silver is half hard. Initial polishing removes about 1/3 of the silver. There’s still plenty left for several tries.
I sell plates to a few modern daguerreians.
Current Pricing. – Quarter Plate $45.00, 4 X 5 $55.00, Half-Plate $65.00.
My stock is delivered to me in 4.25 widths which is the widest material that can be supplied by my manufacturer so I’m not able to offer 5 X 7 or full plate sizes.
