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
 |
"Marble
Brass Rings & Rubber Band"4"x6" watercolor.
This was a sample painting for a watercolor class to show"
limited means subject matter" - anything will work, and
the plane of the paper is defined by how the rubber band and
brass rings sit on the surface. Negative space surrounding
the objects becomes as important as the objects.

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.
