Book conservators are generally familiar with producing their own boards for use in conservation-quality rebinding. Laminating quality matboard has been a common method of producing boards of better composition than commercially available boards. However, these boards lack the weight, "feel", and desirable working characteristics that are associated with traditional pasteboards. The following procedure, using a combination of common materials, was developed to easily produce boards of known quality that duplicate the weight, workability, and "feel" of traditional pasteboards.
Whatman #1 Chromatography Paper - This paper is used as the outer surface of the pasteboard, and provides a clean workable surface. Any fine quality waterleaf sheet of paper could probably be substituted.
Cotton Linters - Cotton linters form the core of the pasteboard. It is easily available, fairly inexpensive, and seems to yield a very flat board when dried. It is possible to substitute blotter, but blotter often yields boards that are warped and must be flattened after the initial drying. I have also tried Abaca linters, which produced a rougher surfaced board that was very tough and solid.
Flour Paste - Unbleached wheat flour was cooked, four parts water to one part flour, until thickened and tacky. The paste should be strained before use and mixed with enough water to reach a heavy cream consistency. Standard wheat-starch paste can be substituted if desired, but it is possible that the gluten and other proteins in flour may yield a harder, less flexible, board.

Paper delivered at the Book and Paper specialty group session, AIC 24th Annual Meeting, June 10-16, 1996, Norfolk Virginia.
Papers for the specialty group session are selected by committee, based on abstracts and there has been no further peer review. Papers are received by the compiler in the Fall following the meeting and the author is welcome to make revisions, minor or major.
