This week we are taking a break from water colour and
working with charcoal. I will bring some sugar paper; some white charcoal or pastel
might come in handy.
The subject is images of fallen trees!
Charcoal is a light black residue consisting
of carbon, and any remaining ash, obtained by removing water and other volatile
constituents from animal and vegetation substances. In
art, the charcoal used is a soft, brittle material in stick or pencil form used for sketching free and expressive drawing, Charcoal is rich and crumbly, and smudges easily.
Lines can be blended easily using fingers or a putty rubber to give great depth
and body to a form. Effects vary according to the surface type of the paper,
we used sugar paper, water can be applied to create a charcoal wash. A spray fixative should be
applied to preserve the finished work. Natural charcoal is black, although
coloured charcoals are now manufactured. Charcoal has been used for drawing
since prehistoric times when pieces of charred wood would have been used.
Today, charcoal sticks are made from kiln-fired willow twigs, and come in a
variety of widths and hardnesses. Charcoal pencils are made of compressed
charcoal, and lose some of the qualities of natural charcoal in the process.
There are various types and uses of charcoal as an art medium, but the commonly
used types are: Compressed, Vine, and Pencil. Compressed charcoal ( also
referred as charcoal sticks) are shaped into a block or form of a stick.
Intensity of the shade is determined by hardiness. The amount of gum or wax
binders used during the production process affects the hardiness. Soft
hardiness leaves intensely black markings while Hard hardiness leave light
markings. Vine charcoal are long and thin piece of charcoal stick that are the
result of burning sticks or vines in a kiln without air. The removable
properties of vine charcoal from dusting and erasing is favored by artists for
making preliminary sketches or basic composition. This also makes vine charcoal
less suitable for creating detailed images. Charcoal pencils are compressed
charcoals that are wrapped with a layer of wood. The design of charcoal pencils
are similar to that of graphite pencils while keeping intact with the
properties of charcoal. Often used for fine and crisp detailed drawings while
keeping the user's handle from being marked during its use. Other types of
artists' charcoal such as charcoal crayons were developed during the 19th
century and used by caricaturists
