From Formulas for Painters by Bernard Stanford Massey, recently discovered at the art supply store:
Medium No. 12
Canada balsam and sun thickened linseed oil
Purpose: Fragrant, viscous like Venice turpentine, water clear - and very expensive - Canada balsam is worth every penny, for it is unequaled in clarity and drying time.
Directions for manufacture: combine and warm the ingredients either in hot sunshine or over a double broiler, and stir them until they mix completely.
Ingredients Parts Canada balsam 4 Sun thickened linseed oil 1 Turpentine 2
Directions for use: Extolled by Laurie for its molecular properties and said to resemble closely the legendary, but unavailable, olio d'Abezzo or Strasbourg turpentine, Canada balsam with oil may be mixed on the palette with tube oil paint for glazing or for painting the last thin coats over oil. For use as a final picture varnish, dilute with Medium No. 12 further with turpentine to permit a very thin application. A this coat of this medium dries withing 30 minutes. Orgegon balsam, although extremely dark, performs quilte like Canada Balsam, yet costs much less.
Paint No. 34
Casein and lime
Purpose: Perhaps the toughest - and certainly the freshest - casein is that formulated in the ancient manner with lime. This casein serves to make a ground or a size, as well.
Directions for manufacture: From a delicatessen, you can buy dry curd cheese, which is cottage cheese without cream or flavoring. make the lime putty according to the directions given in Size No. 11; add the thick putty to the cheese, and stir them together. Leave them for a few hours - the cheese lumps will dissolve completely. Select lime-proof dry pigments and work them up with water into a paste. These may then be combined with casein solution, or kept separate for future use.
Ingredients Parts Dry curd cheese 5 Lime putty 1
Directions for use: Size and then ground mounted cardboard or a panel; use Size No. 4, or the above casein solution, thinned with water. Rigid supports are advisable for this paint, which becomes very hard. You may also use casein-lime as a thin underpaint for oils or paint directly in this material to keep a dull finish.
