| Dry Media | |
|
The dry media
consist of natural or synthetic mineral or plant substances that deposit
crystalline or splinter-like fragments in the paper fibers. Natural chalks.
contained their own binders in the form of clay. Charcoal has none. Artists
or manufacturers also sometimes added binders. When stroked against the
surface of the paper, they deposit fragments in the upper fibers.
Consequently they lend themselves more or less easily to erasure and
correction. In this way they provide the draftsman with flexibility in his
initial inventions. |
