You may recall that I started a series of Lightfastness Tests back in early March. Samples were taped to the windows in my southern exposure studio on March 10. It is now exactly one month later, and I took them down and photographed the results of one month's exposure through double pane window glass. Given that it's taken even the most fugitive oil paints six months to show signs of change when I've tested oil paints, I was quite suprised that after only 30 days, nearly all of these ink samples had faded or shifted (some more than others). Below are some larger images of the test results. You can click on these to see them even bigger:
You can click all of the images here to get large views of the samples and form your own opinions. The biggest surprise for me was the Baystate Blue. Out of the 13 inks I tested in this round, I consider that and the Diamine Red Dragon to be the Biggest Losers. After checking at the two week mark, I figured the Baystate Blue would just lose the intensity of the color, but even the more muted blue left behind is starting to fade. The Kung Te-Cheng was the clear winner in the Lightfastness category.
Some of the inks are presenting only the slightest shift in color at this point, or slight fading. Inks that I feel are holding up pretty well include:
Noodler's Kung Te-Cheng (the winner!)
J. Herbin Rouge Hematite (huge surprise that it's holding up this well, but it is lightening slightly)
Noodler's Nightshade (turning a bit more red)
Noodler's Sequoia (graying slightly)
Noodler's Navy (fading just a hair)
Some colors are exhibiting strong shifts in color, or fading in only certain components of their mix.
Noodler's Kiowa Pecan is losing the red coponent and becoming more yellow
Noodler's Walnut is also losing red and becoming more yellowish brown
Noodler's Whaleman's Sepia is losing the bluer elements, and the ink is shifting to red/pink.
Private Reserve Avocado is fading
Private Reserve Velvet Black is shifting color
Private Reserve Chocolat is losing a little intensity
Enlarge the images above and form your own conclusions. I'll probably photograph them again at the three month mark. If you'd like to see what this looked like before I put it in the window,
here is a link to my previous post.
I have about 20--25 more ink samples to put up in the window today, so stay tuned for results on different inks in another month.
