    Back  again Anyone interested in ferric chloride etching should
    search "Keith Howard" and words like "non-toxic etching". Keith is a
    printmakers who seems to know a lot about ferric chloride. One idea I
    got from him is to use a liquid acrylic floor wax as a "hard ground".
    He suggests adding india ink (I've added acrylic paint) so you can
    see it against the scratched metal. It's good for doing 'intaglio'
    type etching - i.e. fine lines. But you can also paint it on with a
    brush. One thing that seems somewhat critical for success with this
    is to sheet on the wax and let the metal sit vertically (so most wax
    drips off leaving a fine layer of wax) and scratch through the wax
    with a scriber after about 20 minutes. If it gets too dry the edges
    seem to lift off - so the 20 minutes seems important. 

    Someone mentioned not using Sharpie pens. I agree. I use Staedtler
    Lumocolour permanent markers  in the transparent colours (red, blue
    etc - NOT black). 

    By the way, I am scheduled to teach a married metal and etching
    course at Metalwerx in Boston this summer, if anyone would like to
    learn more.  I also have notes on my website on etching with ferric
    chloride. It's a technique I love. Once you try it, you get hooked.
    It's also a great technique to teach to beginners as the results are 
    always impressive.
