It is natural to have preferences between types of media. Some characteristics match our aesthetic sensibilities and since we are creatures of honor and conviction, we find it hard to switch allegiances,but the cure might be easier than we imagine.

an expression from the depression era, "Make it do, wear it out, use it up, do without".

I received a gift that sparked a memory. I received a book "Formulas for Painters (200 formulas...) by Robert Massey. Leafing through the book I saw warm home made hide glue used as a medium with pigment mixed in to make paint. Upon hardening it is varnished with a dilute solution of formaldehyde to make it behave as a conventional paint layer and provide a fungicidal assist for the glue. It seems an extreme case of making it difficult on yourself, but there was a reason for this mixture. One instance was Franz Klein. He immigrated to America at just the wrong moment. The Depression caused the creation of the Works Progress Administration to offer small subsistance level jobs to artists to help them survive until the recovery. One limitation was "no recent immigrants". Franz Kline was not eligible, and in typical artist fashion, he made do. He collected discarded telephone books to paint on the paper pages right over the print. For paint he mixed glue and soot from kerosene lamps, limiting himself to small black & white examples on recycled newsprint. He could not afford even the basest dry pigment. He used thelittle paintings as preliminaries later producing large canvases as the economy recovered and people bought his paintings. He had used a very ancient medium to work and eventually give rise to some of the most impressive graphic images in all of abstract expressionism

Homework

class #11

Homework # 11 "mixed media" as the only requirement in making an image You need not invest in expensive paints, but try to produce the most useful combinations for this assignment.

WHEAT PASTE RECIPE

ingredients:
Flour (bleached pastry wheat flour) 1 part by volume
water 10 parts by volume
Alum 1/2 tsp to each pint of paste

To the flour add enough water to make a slurry. Shake in a sealed jar until all the lumps disintegrate, may be left to stand for an hour. Place slurry in a double boiler, boil remaining water and slowly add to paste stirring until paste thickens. Add alum, then add a few drops of thymol dissolved in alcohol to prevent mold & mildew [formaldehyde was used formerly, however thymol is less dangerous to use. [1/8 tsp of thymol crystals dissolved in a pint of denatured ethyl alcohol may be applied a few drops at a time with an eye dropper to paint or glue solutions to prevent mold & mildew.

Mounting paper one on another. - Directions for use: brush a thin coat on the back of the paper to be mounted, tip on to the receiving paper surface [prestretched or place under stretched damp brown wrapping paper to dry thoroughly before removing. Or place in a vacuum table to flatten without wrinkling.

Matting work on paper under glass: wheat paste is best for securing art to backing under a rag mat, using mulberry or rice paper Ts. The weak link is the rice paper. If the matted painting falls off the wall or is dropped the T tears and not the art paper.

RICE FLOUR RECIPE

Another version of this uses rice starch or rice flour (from asian foods section in grocery) as a substitute for pastry flour. All else is the same except the rice flour usually has fewer lumps and is easier to find than pastry flour most times.

ANOTHER SIMPLE PASTE: METHYL CELLULOSE

Methyl cellulose, the main ingredient in most commercial wallpaper pastes, is acceptable for conservation purposes if used in its pure form. It is available from conservation suppliers as a white powder. Mix one rounded tablespoon of methyl cellulose powder with 1/2 cup distilled water and let stand for several hours. Thin to the appropriate consistency with distilled water. Methyl cellulose is not so strong as starch paste but should give adequate support for objects of moderate size. Methyl cellulose paste keeps for several weeks and does not require a preservative or refrigeration.

APPLYING HINGES

Apply starch paste or methyl cellulose to one side of the hinge with a small stiff brush before the hinge is put in place. Cover the hinge with a thin layer of paste. Position the hinge, using tweezers if necessary, and tamp it lightly with a small piece of blotting paper. Weight the hinge as it dries to
prevent cockling of the object. Hinges may be weighted as follows: place a blotter over the area to
be dried. Place a small piece of glass over this with a weight of at least one pound on top. Small bags of lead shot or lead fishing weights from a sporting goods store are excellent. The hinge should be weighted until it is dry. Changing the blotting paper occasionally will speed up the process.

Folded hinges will sometimes stick together as they dry. one way to prevent this is to insert a piece of household waxed paper between the two parts of the hinge. Conservators use release paper or polyester web (available from conservation suppliers).

It may take time before hinging comes an easy task, but persistence and practice does pay off.

 


"Memorial Day " 22" x 30"
by JRJ watercolor & collage
on Aquarelle paper.

 

Wheat paste, rice starch paste and methyl cellulose all make excellent adhesive binders for mixed media or collage. As conservation materials they are "reversible", which means they can be removed at some later date without destroying the art. They represent an old school philosophy toward mixed media, and are worth knowing, however the cure-all for most mixed media problems is "plastic" Use acrylic adhesives and you produce a homogenous whole, a light resistant complete package that is just short of bullet proof. A well varnished acrylic painting could be used as an awning in a rainstorm with little or no damage to the paint layer. Likewise, incorporating any paper or cloth materials under an acrylic protective coating means it will last longer than any oil painting with only the tiniest of changes due to age and light fading. Wet acrylic has a slight whitish tint until completely dry, so colors appear lighter than they will once the water has evaoprated. It is a small negative attribute to have to cope with by comparison to what is gained. I believe acrylic paint is the wonder medium of our age.
