Rokusho is a traditional solution for coloring alloys. It can
produce a broad range of effects. Much of the beautiful patinas you
see on Japanese hollowware and sword furniture is from this
product. Here is what we know:
We will sell it in three sizes:
The shelf life dry seems to be years. Mixed up I am not sure as of
yet. The following is a rough draft of the basic instructions. We are
still playing with it. Nothing is written in stone
One liter filtered water
Substitute: Stainless steel and /or Pyrex container with copper scrap
in the bottom.
Diakon Radish, grated to a paste
Optional Additions to Rokusho:
3g cubric sulfate(?)
One Akaume Zuke Pickled Plum(oriental grocery)(Better reds?)
Heat the solution to a simmering boil.
Rub the diakon radish paste on the surface and leave it there. It is
reputed to protect sterling from discoloration and to improve the
evenness of the patina.
Submerge the piece in the hot solution. This can take from 10
minutes to an hour. Remove the piece occasionally and check for
color. Never let it dry. Remove, rinse and pat dry.
This patina is traditionally fragile and should be sealed. Paste wax
and Renaissance Wax are excellent.
As far as we know we can ship it anywhere. It is essentially
pigmant. It is a dark green, moist powder and smells like a urinal.
The primary components are copper carbonate and calcium carbonate. I
have a dozen home made formulas and none contain these products.
So, that is the story. I am placing our first order for stock in the
next day or so.
