Note: If you're a vegan or vegetarian this listing is probably not for you as it involves using animal parts, so read no further!
If you're not a vegan or vegetarian this ancient material can be used for the centuries old method of sizing or applying gesso with ingredients available at that time to a canvas or panel as a ground for oil painting. Before they had PVA or acrylic glues and mediums, glues were made from animal parts; parts of the animal after it was butchered for meat, that would not be consumed. That way more of the animal was used, and since it was going to be used for food anyway there was no "killing for art" involved!
The supplier sells this as an ingredient in the making of "true" or traditional gesso, a ground for oil painting on wood panels or canvas. The supplier of French chalk (see above link for our French chalk) says it is another ingredient for making traditional gesso. They also say rabbit skin glue (RSG) and French chalk are ideal ingredients for making a ground ("bole") used in water gilding. For further info on using RSG in gilding, use this search: { https://www.google.com/search?ei=4VUSXY6wF4mV8APRk7CABg&q=gilding+with+traditional+bole&oq=gilding+with+traditional+bole&gs_l=psy-ab.12...28608.29547..33173...0.0..0.1123.4441.6-3j2......0....1..gws-wiz.......0i71.Djf77pqYi6U }
The CAMEO art materials database says this about RSG { http://cameo.mfa.org/wiki/Rabbitskin_glue } :
"A strong, water-soluble adhesive obtained from the hydrolyzed products of the skin of rabbits. Rabbitskin glue consists primarily of gelatin and other protein residues of collagen, keratin, or elastin. These agglutinating materials are broken down in boiling water; the cooled solution yields the jelly-like glue which is cast into flat sheets. Rabbitskin glue is a dark brown and tends to be more flexible than bone or hide glue. For many years, rabbitskin glue was the preferred adhesive for gilders."
If you google "rabbit skin glue gesso" you'll get several results. Three videos, and assorted articles. Looking them over, you'll see that making RSG gesso is not a trivial undertaking. It requires a fair amount of mixing, heating, general alchemy, and takes several days before it's done.
I'd suggest watching one or all three of the videos. They gives you a good general idea of what it's all about. Watch the Clive5art video first.
After that, you can get very detailed instructions from the site just below. It's one of the best articles, which gives lots of details and clear, step-by-step instructions. It's oriented for making gesso for oil painting on a wood panel:
{ https://www.artistsnetwork.com/art-techniques/homemade-gesso-recipe-for-a-true-gesso-panel/ } :
It's from the Artists Network. Here's what they say about the amount of work involved:
"Four to six days from start to finish are required to create a true gesso panel using a homemade gesso recipe. Only one (or two) of these days is a full day. The other days involve anywhere from a few minutes to an hour of work."
The article lists the equipment and ingredients you'll need. Ingredients: Dried RSG granules, white chalk (calcium carbonate) or gypsum (calcium sulfate dihydrate), water, and (optional) titanium dioxide.
Equipment: A diet or postal scale for measuring, One quart measuring cup, Burner, Double boiler, Extra pot, Large spoon, Mesh strainer, 1- to 2-inch flat bristle brush.
Wikipedia { https://en.wikipedia.org/wiki/Rabbit-skin_glue } has an article on RSG oriented for use as sizing for oil painting on a canvas:
"Rabbit-skin glue is a sizing that also acts as an adhesive. It is essentially refined rabbit collagen, and was originally used as an ingredient in traditional gesso.
In traditional oil painting as practiced by the Renaissance painter, rabbit skin glue was used to seal the canvas. This is necessary because the linseed oil that forms the base of most oil paint contains linolenic acid that will destroy the canvas fibers over time. Renaissance artists also knew that pure size (hide glue) became brittle once dry, and would mix it with oil and chalk to make a "half-ground" for canvases. Pure hide glue was usually applied only to rigid supports like panels. Though this does help to seal the canvas or panel, artists still applied a layer of "oil ground" which was often lead based paint in order to provide a binding layer for the final oil paint to adhere to. The primary purpose of Rabbit-skin glue was to protect and seal the canvas."
The article also includes info on using it as sizing for canvas:
"Sizing
When used in painting as a sizing, it is spread thoroughly over a canvas that has been placed on the stretcher. When the glue dries, it tightens the canvas. After this has been allowed to dry, an oil-based primer is then applied. A canvas sized with rabbit-skin glue can be made tighter than with other alternatives—such as an acrylic-based gesso—because of the shrinkage. This type of canvas is also valuable because it can be sanded to a flatter texture, which allows the painter to achieve a finer level of detail than can be achieved with a typical acrylic gesso ground.
This rabbit-skin glue ground is only appropriate for use under oil paint. Acrylic-based media will flake off a canvas prepared with rabbit-skin glue and are therefore not appropriate."-
