Rabbit Skin Glue is made from rabbit skin, bone, and tissue. A variety of artists have found a need for this product, whether utilizing it in canvas sizing or preparing a traditional gesso with it. In fact, rabbit skin glue has been used for centuries as a traditional organic sizing material to prepare canvas for oil priming. However, conservation scientists have cautioned painters that rabbit skin glue absorbs atmospheric moisture on damp days and swells while it gives off moisture on dry days and shrinks.
Gilders also use rabbit skin glue to prepare bole.
Rabbit skin glue can be mixed with titanium white and precipitated chalk to create a dry gesso which is an ideal surface for encaustic and egg tempera paintings.
