Have you lightfast tested any other of the Derwent pencils? I'm curious especially about the Derwent watercolor pencils.

Katherine

I use Derwent Drawing mostly for drawing people as I find the colour range works well with a quasi-classic drawing approach.

Very difficult to find in open stock though!

Julie Oakley

What's the problem with graphitints?

Roz

Pearl, if you click on "Derwent" in the categories list you will find a test and review about Graphitints which are watercolor pencils of a sort. They are very fugitive as are the Derwent Inktense (they are so fugitive you don't want to get near them!).

As for the regular Derwent watersoluble colored pencil line I have not tested that. I did use it a fair bit with other lines, in the late 90s early 0s but I don't like the wash out when working with it. I prefer Faber Castell Albrecht Durer Aquarelles. I only use both for sketching so I haven't done a lightfast test. I should probably do one on the FCADAs because I have some projects in mind for finished art.

I'll keep you posted.

Roz

Katherine the Derwent Drawing are perfect for life drawing situations because of their color range as you mention.

I'm disappointed to hear it is no easier to find open stock of these pencils in the UK than it is here!

What is the purpose of sending little self-contained tubs of preselected colors to vendors? It doesn't make any sense to me. How do they know what colors people really want?

Sigh.

Roz

Julie, click on "Derwent" in my categories list and scroll down to the third post Oct. 9 (my first blog post actually). It reviews Graphitints, and shows a shocking lightfast test.

These pencils are very fugitive. So fugitive in fact that I gave them to friends (who knew the score) in life drawing rather than give them to my 6-year-old-niece. She deserves better art materials.

I don't even recommend them for journal work based on friend's experiences.

The posts above include some rather harsh comments about lightfastness in certain ranges of Derwent pencils. If the issue is considered in more detail then conclusions can be more positive.

Derwent now publish Blue Wool lightfastness ratings for all their pencil ranges. See http://www.pencils.co.uk/products/derwent.aspx click on any type of pencil listed at left of page, then at the bottom of the main body of the page for that type of pencil click on "Colour Chart and Lightfastness Ratings".

The published charts show that the types of pencil criticised above do indeed contain fugitive colours (Blue Wool 2 or 3 for example), but also many lightfast colours (Blue Wool 5 to 8 say).
Selecting only the most lighfast colours is therefore an easy task. Rejecting an entire range of pencils because it contains some fugitive colours is unjustified. The fugitive colours are manufactured because some customers value those hues - but not for wall hanging display!

Each step in the Blue Wool scale doubles (or halves) the light exposure time to a given degree of fading. So comparing a BW3 pencil with a BW7 pencil, the BW7 pencil will last 2x2x2x2 = 16 times longer for the same fading.
All the Derwent "Drawing" pencils are BW7 or BW8 - as confirmed by the test result (sigh of relief) at the top of this page.

Roz Stendahl

Andy, I'm sorry you feel that reporting on my lightfastness tests was harsh. I can only report on what happened. If you read the other posts relating to the Derwent lines with which I have problems (Graphitints and Inktense) you will see that the ENTIRE RANGE of pencils in those lines faded.

That's not a matter of one or two colors not making the grade.

I want to love Derwents, as they are the pencil of my childhood, and in Derwent Drawing, at least I can be confident that the pencils colors won't fade, hence this article.

I hope you will see from these related posts that I am being fair. If I were being harsh I would simply dismiss Derwents because two of the company's lines failed so badly.

Instead I prefer to look at every line and see what happens. And report on that so that people can be made aware.

I appreciate you sending a colour chart lightfast ratings link for Derwent so that people can go and look up individual pencils across their lines.

Sadly, not all colored pencil consumers are savvy to the fact that some pencils might be in a line, suitable for art that is not made to last—such as some illustrations which are made for the moment, digitized, and the originals not saved. The company doesn't announce this on their boxes of pencils so people new to colored pencils or who don't work in the profession, won't understand this and will be disappointed when their work, which they were making to hang on the wall, fades.

That's the purpose of posts like this—to provide information to artists who might be new to all this or new to the medium. Advertising copy can be misleading, or simply leave out details that new adopters might need to make a reasonable choice with their limited art dollars. As an instructor in colored pencils it's my job to point these things out to people.

I'm glad that Derwent now publishes the lightfastness ratings for their pencil ranges (I seem to remember someone else wrote in about this link on another post), but I would be even happier if Derwent (and all colored pencil companies for that matter) published this information on their packaging all the time—as soon as they launched a product. (I know that some colored pencil companies do this.)

I would like to see ratings right on the pencils themselves (like tubes of watercolor paint show) so that users of colored pencils don't have to look at charts at all, but can simply look at the pencil barrel they hold in their hands and make an instantaneous decision.

I hope people will consult the list on their website until that happens.

Also in the meantime, it's hard to see how "conclusions can be more positive" about a pencil line when ALL the colors in that line fade and all the advertising promotional material for that line (like Graphitints for example) talks about making art for wall hanging. Ultimately the companies are responsible for what they put out into the world, and the advertising they use to promote it. I know my posts on Derwents have been fair and accurate with a clearly defined scope.

If you read my posts again carefully, you will see that I am not rejecting an entire line because "it contains some fugitive colors." I am rejecting the lines I reject because ALL of the colors failed. That's not subtle.

I am still a happy user of Derwent Drawing. And I'll continue to purchase and test any other lines the company produces in the future, always with the hope of finding a quality line with lightfast qualities.

Again, thank you for providing the link to their lightfastness charts.

Andy Newton

Roz - Your June 10 2010 comments above make complete sense.

Sharing any more information that we can glean about pencil permanence must be helpful. As you say, the advertisements and pencil tin packaging often does not help us much.
So here is one more link and recent experience to share:

In May 2010 I bought a Derwent Artists "Burnt Carmine" pencil from open stock. Its texture was so different from other Derwent Artists colours that I asked if this was correct at the Derwent enquiry page here:

http://www.pencils.co.uk/enquiries_form.aspx

(I set the "Area of interest" field to be "Products".)

Would there be any response? Web based enquiry forms often lead to nothing more than one automated reply.... but in this case, two days later by email...

--------------------------------
Hello Andrew,
It certainly sounds like you have acquired a rogue pencil. We take our quality very seriously here at Derwent, so if you wouldn't mind, could you send the pencil back to us so that our lab can test it to find out what problem has occurred in the production process, and I will send you out a replacement.
--------------------------------

All sorted in a few days, and top marks awarded to Sarah Taylor, Product Manager, Cumberland Pencil Company!

So given this example of care over product quality and good customer communication, what about your lightfast results that were so different from the published Blue Wool levels? (Sixteen of the Graphitints are rated BW7 or BW8 should be virtually bulletproof.)

An enquiry to Derwent would certainly be worth doing, with a link to your well documented test at http://rozwoundup.typepad.com/roz_wound_up/2008/10/derwent-graphit.html

Roz Stendahl

Andy, I am thrilled to hear how responsive Derwent was to your enquiry about your "rogue" pencil! Thank you for your excellent suggestion and the link to their enquiries form.

Annna

I think that most water soluble pencils have at least some issues with light fastness. For example F.C's Albrecht Durer pencils are based on the same pigments with the same colour range as their Polychromos pencils and although many A.D. pencils are light fast, they generally have lower light fastness than the polychromos in a lot of pencils, especially the red/violet shades. A Faber Castell rep said they don't yet know why this is the case, but the watersoluble binder affects the lightfastness. Faber Castell have a one-, two- or three-star lightfastness rating system and these are printed at the end of the pencil, very useful.

Roz Stendahl

Anna, I used F.C. Albrecht Dürer line for watersoluble colored pencils too and while there are issues with any of these it holds up in ways that the Graphitints and Inktense don't. Again, if there is clear labeling and up front advertising then people won't be disappointed.
