ABSTRACT
The gum 'dimroom' can be as simple or as complex as one's budget allows. There are one or two chemicals in the gum dimroom that are hazardous: dichromate, for one, and formalin or glutaraldehyde if sizing the classic way. This chapter describes essentials for the gum dimroom. Hahnemhle released an incredible alternative process paper. It is a paper to choose for our alternative process dimroom if wanting one paper to 'do it all'. Hahnemhle is also the manufacturer of other fine art papers: Lanaquarelle Watercolor, Cezanne, and Leonardo. Arches Platine is another great paper that works well with many of the paper-picky processes. Bergger Cot 320 is another good paper very similar to Arches Platine. There are other choices that gummists have used, some of these in the form of watercolor pads which are conveniently cut to size already, namely, Arches Aquarelle, Bockingford, Atlantis Silversafe, Saunders Waterford and Lana Aquarelle.
