    Sorry I am late in answering. I am not Steve Walker, but I took an
    excellent workshop from him at Peter's Valley on Mokume and Married
    Metals two years ago. Steve likes to use heat to make his patina - no
    chemicals. The bright reds are from copper. Steve taught us to clean
    the metal completely and put it into a clean toaster oven that was
    preheated to 400 degrees F. Watch it carefully and pull it out when
    you hit the shades you want. All sorts of other colors can also be
    obtained depending on the heat, time in the oven, and alloy. The
    toaster oven produces a more even heat than a torch and is cheap ($20
    or so at Target) Yes, the heat patina will not last forever, but take
    your pictures while the colors are at a peak and enjoy them for a
    while thereafter. Chemically created patina (such as salt and LOS) is
    not permanent either. (except for grey and black)
