Last autumn I made a batch of homemade walnut ink (http://markgodofthunder.blogspot.com...lnut-ink.html)
, but I was somewhat frustrated with my inability to find any information on the Internet regarding how lightfast it is. Many sources said that it was lightfast; some said that it exhibited a small amount of fading over time, but the fading enhanced the color and look of it; other sources simply referred to it as fugitive.
So I decided to run my own simple test. I painted smears of the ink on some printer paper, blocked off areas of the smears, and sat the paper on my car dashboard. It remained on my dashboard, exposed to the sunlight, from November 6, 2007 until March 26, 2008. Then I took if off the dash and photographed it.
Iím pretty satisfied with it. It exhibited a little fading in the exposed spots, but itís actually very hard to tell. If I hadnít marked off the exposed areas with a pencil, I donít think Iíd be able to tell the exposed areas from the covered areas.
4 months and 20 days might not be long enough to be sure, but I think that itís pretty good evidence that it wonít fade an awful lot. I feel better about using it now.
Iíve done some sketches and drawings with it, and Iím pretty happy with how they look (I posted a few here last Fall, but nothing recently until now.) Here are a few.
Iíd love to hear any comments on the drawings belowóharsh criticisms are very welcome!
(Iíll try to post pics below)
