Graphite from Ceylon (Sri Lanka).
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.

Composite of original photos of artists' graphite art and enamel spray art and gouache printable to 50x30 inch.
from a figure drawing night at One Grand Gallery in August 2024. I was using graphite sticks, pencils, and erasers on smooth layout paper for a soft effect.
This was the 22nd pose, 5 minutes in duration.

Today I took 3 of my finals. So that leaves only one more final critique for Drawing and then I'm done! Right after I finished I went to work until 6. When I got home I drew until Alex came over.
After James from Studio RSR told us he was moving from his G20 into an F87, we saw it as another opportunity to team up again. With our V710FF wheels, him and his team were able to put together a monster on the track.
