Learning Event 1:
IDENTIFY AND DESCRIBE THE TOOLS USED TO APPLY, REMOVE, OR AFFIX
THE IMAGE TO THE DRAWING SURFACE
1.
Tools are used to apply, remove, or affix the medium to the drawing surface. A tool can
join the medium like graphite in a pencil. Read the descriptions of some of the tools below.
a. Pencils, the most commonly used, least expensive drawing tools, are actually the
casing surrounding a medium. Charcoal, carbon, and graphite are the most common types of
pencils used in realistic drawing.
(1) Charcoal comes in five grades and can be in stick or pencil form. It produces a
dull, dense black line. These pencils come in six grades from 10B (very soft) to HH (medium
hard).
(2) Graphite (mistakenly referred to as lead) pencils are graded by hardness (fig 1-1).
Lead is a soft, very shiny metal. Lead pencils are rare today, and have been replaced by graphite.
