Fallen Trees in charcoal

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
