This seminar will deal with dry media, which I define as those media with which a drawing or painting may be made without a chemical vehicle. A binder is present primarily to hold the medium in the shape of a drawing tool. Drawings or paintings made with dry media depend upon roughness of the support or ground to file pigment off the drawing tool. The pigment lies on the surface, adhering by mechanical or physical forces. The degree of adhesion depends upon the nature of the support, pigment particle size, and the pressure applied to make the stroke. Therefore dry media are easily smudged and abraded. Though mechanically they are fragile, they are in many ways more stable than media using liquid vehicles since they are not subject to the same chemical alterations. I will talk about these aspects with respect to metal point, pencil, charcoal, chalk and pastel. My discussion of the first four will be brief, covering only history and technology and a few points on conservation. I shall spend the most time with pastel since it poses more problems for conservators and the other media share similar defects.
