            <div align="left">Part of my absence in July has been my attention to many projects
            at work.  Plans for a series of lectures and a demonstration in October at the <a href="http://www.scad.edu">Savannah
            College of Art and Design </a>have taken up large parts of my workday. Another exciting
            opportunity to contribute to the art world has developed over the last month.<br /><br />
            Mark Gottsegen has become more involved in his venture to provide lectures and educational
            opportunity for the art community through his organization <a href="http://www.amien.org">AMIEN</a>;
            he asked me to take over his previous position as Chair of the American Society for
            Testing and Materials for Artists’ Materials (<a href="http://www.astm.org">ASTM</a>).<br /><br />
            This will be a great personal challenge for me. In recent years, participation by
            manufacturer members has been slipping. While this may be a part of a natural cycle
            of interest in ASTM as the Artists’ Materials group moves from creating standards
            for some of the high visibility, large volume art materials to the smaller-revenue
            generators in a manufacturer’s product line. Regardless, a lot of work will need to
            be done to bring back some of the old familiar participants and attract a new generation
            of enthusiastic manufacturers. Exciting new products are coming into the marketplace,
            and both the consumer and manufacturer stand to benefit from participation in ASTM.<br /><br />
            Education of the public is lacking. Many artists I contact do not know the work of
            ASTM. Others see it as “that group that does the health and safety thing.”  This
            “health and safety thing” is more commonly referred to in ASTM parlance as D4236. 
            This standard was a major undertaking by both ASTM and the Congress of the United
            States when they decided that art materials needed to have some point of official
            contact so that— if by some reason an art material was ingested or came into accidental
            contact with sensitive parts of the human body—a source of authority on the composition
            of the product could communicate with health care professionals to provide vital information
            on the composition and toxicity of the material in question. Other standards familiar
            to artists relate to the lightfastness of art materials. ASTM has provided manufacturers
            with a forum to come together to evaluate the durability of pigments. While many pigments
            remain unchanged when exposed to light over long periods of time, other pigments fade
            and pose problems for the artist. ASTM provided the means to test and evaluate the
            major pigments used for making art materials, and ASTM came up with a rating system
            that’s easy for an artist to understand.<br /><br />
            My task, and the task of those who wish to help, will be to educate artists as to
            the importance of ASTM and how their involvement as smart consumers can influence
            the art materials industry. If the public desired new standards, ASTM could provide
            them.  This would forge a partnership—between the consumer who wants quality
            art materials and the manufacturer who could provide them.  In my time as an
            observer of the art materials industry, I’ve impressed overall with the genuine care
            and concern that manufacturers have toward their customers. I believe they want to
            sell good materials because it makes good business sense, and it’s the right thing
            to do.  Many manufacturers are artists as well; they accordingly feel a sense
            of responsibility to produce good quality art materials.

                     had the wonderful opportunity to attend the IAPS meeting in Albuquerque, NM, last
                     week and delivered a lecture on lightfastness testing of pastels. The audience was
                     fantastic! Lots of great questions were posed on the issues involved. I believe that
                     pastel artists have become accustomed to the notion that some pastels fade when exposed
                     to light. My presentation on lightfastness problems concerned the audience but did
                     not shock them as it did when presented several years ago by one of my colleagues.<br /><br />
                     The key to getting manufacturers to create reliable pastels will come when the American
                     Society of Testing and Materials (ASTM) establishes a pastel standard. This standard
                     will map out the protocol for conducting lightfastness testing, enabling manufacturers
                     to test and evaluate pastels they make so if several color mixtures don't meet adequate
                     lightfastness ratings, they can reformulate the pastels.<br /><br />
                     That standard is a year or two away from completion—if no serious impediments come
                     in the way of the current writing and preliminary testing process. The one refreshing
                     aspect to this pastel standard will be that finished pastel products, not just the
                     pigments themselves will be evaluated. This is important because some pigments can
                     perform well without any additives, but when mixed with other components, the combination
                     of materials will result in an unstable product in terms of lightfastness. The opposite
                     can be true as well. Unstable pigments may perform well when mixed with other pastel
                     ingredients and prove to be highly lightfast.<br /><br />
                     Pastel artists don't have to be held captive when it comes to knowing what colors
                     are good performers and those that fade fairly quickly when exposed to light. A protocol
                     that provides a very good indicator of how materials will behave if exposed to light,
                     is available for anyone to use. The method is fairly simple. Artists can prepare a
                     suitable sample card that exposes a portion of the pastel to light while leaving a
                     portion masked from any exposure. For a how-to on testing your own pastels for lightfastness, <a href="http://www.artistsmagazine.com/tam_qnaarchive.asp?id=2997">click
