Lightfastness Tests -- Faber Castell Polychromos Pastels

Faber Castell Polychromos Pastels have been a go-to pastel for artists because they are individually rated for lightfastness, and provide a wide range of colors among the harder brands of soft pastels. Having a lightfastness rating does not mean that a color will never fade; it just means that the company is telling you the degree to which the color is lightfast, compared with other colors.

For these tests, I assumed that the earth colors and grays are about as lightfast as you can get, so I didn't test the entire line of Polychromos. Instead, I pulled out 74 colors from the full set that I thought would be most inclined to fade or shift color. The samples have been in my south-facing studio window in the northeastern US for at least a few hours a day for the past five years. The

Lightfastness Tests -- Charvin Water Soluble Pastel Painting Sticks

In January, 2015, I made swatches of the 48 colors in the Charvin Water Soluble Pastel Painting Sticks set, and cut the strips down the center. I put half of each strip by a south-facing window of my studio, and the other half wrapped up in a dark closet. In another month, it will have been five years since I started the test. By art longevity standards, five years is not a long time.

In case you're not sure which pastels I'm referring to, above is a photo of the set. Here is a link to them on the Jerrys website. They claim to be pure pigment and lightfast. They are certainly well priced! As you can see in the image below, the colors are rated by the manufacturer, some as "**** Excellent" and some as "***Good". But if you know me, you know I often need to prove things for

Hudson River and Palisades Pastel Sketch

This pastel sketch is about 7x9", in my Stillman & Birn Alpha book. It was done on a page with a prepared border, but for the first time, I encountered something that I think looks a whole lot better without the border. I coated the inside part of the two-page spread with Golden Acrylic Ground for Pastels.

The sketch is based on these four sketches that I did on location plus photos I took there, as preparatory work for a large commissioned oil painting. When I was finished with the sketch, I was so glad that the pieces of glassine were already cut and tucked neatly into the book pocket! (Click here and then scroll down that page, to see the glassine pocket and instructions on making one.) That made it super easy to position them over the pages, glue down the edges with a glue stick, and close the book!

Here's what the sketch looks like with the full pages showing, including the border. You can see how the glassine covers get pulled aside to view the sketch. I had to glue the glassine down onto the side borders, so those became partially obscured .

Although I've done loads of pastel work, I don't think I've ever done it across a two page spread before. It was definitely a challenge getting those chunky sticks into the center, but it's a nice change of pace in leafing through the book. I was glad I gave it a try. I might try one on the plain paper too, without painting it first with the Pastel Ground.
