I'm trying to reproduce the hammered copper hardware used by Gustav
Stickley. Any advice ?
As a rough guide, here's just one web picture of the style:
I know the finish I'm after. I think it's probably lighter than
Stickley is today, but I have some traditional copperware from
Nagasaki (it's a traditional local craft there) that's exactly what I
want. Sharp-edged indents for the hammer effect, and a very bright
abraded edge to the top of these, all on a darker ground.
I'm currently working 20 gauge sheet. I can hammer this easily enough,
but I just can;t get the whole sheet to take sharp edges. Is this too
thin ? It seems (this is crazy, but it's what it appears to be doing)
as if annealing the sheet to work it further "relaxes" the edges and I
find myself with rounded snake-like patterns between the indents.
Secondly, what should I use as a patination ? I'd be interested in
anything that other makers of such Stickley repros (I know you're out
there) are using.
Using the techiques from "Colouring, Bronzing & Patination of Metals"
I'm thinking of either 3.35 or 3.70 Both of these are copper
sulphate / ferrous sulphate mixtures, one an acidic solution with
acetic acid and the other with zinc sulphate and potassium
permanganate as an oxidiser. Is it worth trying the nickel sulphate
or the rokusho recipes ? I'm certainly too wary of antimony
trichloride as an ingredient !
