Tools



Watercolor is a natural place to start the study of painting materials and techniques. It has been around longer than paper and easily predates watercolor brushes. Some people consider that the cave paintings at Lascaux might be the first watercolor, since earth pigments were mixed with water and applied directly without any binder save perhaps saliva. In that way, the cave paintings might also be called the first air brush painting, since a hand stencil image was left on the wall when water and dirt(or earth pigment) were spit around the hand.

Watercolor paint semi- liquid in tubes or dry cakes in pans are all made by combining dry pigment and gum arabic. Other gums have been used, but none work as evenly and consistently. The gum allows the pigment to go into solution with an even dispersion of almost all pigments in water. Gum arabic is the magic glue that puts it all together.
It is the constant in other watercolor based media: gouache, casein & egg tempera. The first egg and oil emulsions exploring oil as a medium, included small amounts of gum atabic.

Watercolor paint especially in tubes, is a good foundation for our future media exploration. The gum does not hamper or affect experiments in acrylic painting.

Homework


[images of gum arabic & dry pigment from Daniel Smith Inc.]     

I would like us to produce two kinds of homework: a painting outside of class, and WC sketches in the sketchbook. Try to do the paintings and sketches every two or three days to develop your eye-hand coordination – rather than doing them all at once. Someone who draws and paints every day or two will accrue twice the benefit of the person who does them at the last minute before class. You may show or not show the companion exercise. Select and send only one image per homework assignment. Either sketches or fully developed images will be acceptable. Try to show the pleasure you found in doing the work.

This is my process:Begin with a careful drawing, erase as much as possible before using color, the gum arabic in the watercolor paint prevents further erasures without destroying the paper surface. Another alternative is to make the layout drawing using a blue watercolor pencil, no erasing will be required.

Begin and practice drawing from life. Two eyes see better than the single eye of a camera, and it is easy to shift your viewpoint as you work. If you must work from a photo, make sure it is a good value study, but be willing to deviate from the reference image to benefit the painting. It is not the point "to accurately copy", but to use a photos strengths to benefit the work. Always work from your own photos to avoid problems.

[Our First Homework: a leaf or two and a rock] I believe in simple images, and I believe that each of us should choose our own combination of subjects and composition. Even in beginning classes, I require that the artist take responsibility for the image from the start. I may propose a subject or provide a still life, but the graphic composition selection is of primary importance, and the interest in the work is directly related to each of us making our own selection. Do what interests you even when it is not the image under consideration. With each of our exercises this will be the first consideration. Try to give a sense of scale in your composition, and select items interesting to you. You may also provide subject photo images to accompany homework submissions, but the point is the painting. The subject is only the starting point and the excuse for making a painting. As I receive the images, I will build a homework page for this first class.

The paint

gum arabic
Watercolor paint like all paint begins with dry pigment and a binder. Gum Arabic is the primary watercolor binder for both tubes and pans. The pigment is ground into distilled water and liquid gum arabic is added. Originally Gum Acacia from Senegal and nearby regions of Africa. It acquired the name Arabic because Arabs closely held the secret of location and production for centuries maintaining a world monopoly. Like spices from Cathay. The name of the supplier became associated with the product.
Cheaper grades of watercolor paint have extenders and emulsifiers (glycerine) to extend shelf life, and use lower intensity pigments. Higher "Professional" grades use a higher percentage of pure high quality pigment and little or no emulsifiers or extenders.
