This was flat black paint, after allowing it to cure I took some cotton fabric and rubbed it with a dense graphite. This was then rubbed all over the flat black to get this texture.
The clear coat will darken it pretty dramatically, so going a bit heavier on this pass is a good idea.

This is one of my favorite pieces from my art class. She is a Bengali girl cut out from a National Geographic magazine.

A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 5900 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
Elements are fundamental substances of matter - matter that is composed of the same types of atoms. At present, 118 elements are known (four of them are still unnamed). Of these, 98 occur naturally on Earth (hydrogen to californium). Most of these occur in rocks & minerals, although some occur in very small, trace amounts. Only some elements occur in their native elemental state as minerals.
To find a native element in nature, it must be relatively non-reactive and there must be some concentration process. Metallic, semimetallic (metalloid), and nonmetallic elements are known in their native state.
The element carbon principally occurs in its native state as the minerals graphite (C) and diamond (C). Graphite is the common & far less valuable polymorph of carbon. Graphite has a metallic luster and a silvery-gray color. It is very soft (H = 1), has a slick, greasy feel, and readily marks paper. Graphite does have cleavage, but it is not apparent at the hand specimen scale. The ability of graphite to mark paper, its softness, and its greasy feel are all a consequence of cleavage sheets easily slipping over each other on a microscopic scale.

Special thanks to Ali Stewart from Scotland who graciously allowed me to use a photo from his amazing collection. Thanks Ali!
Rebecca at Derwent kindly sent me this lovely gift of 12 Graphite Medium pencils after we connected on Twitter and I mentioned my love of sketching.
Awesome little surprise to have come in the post!
