The mineral graphite is soft enough to leave a mark on paper. We use graphite, which is a form of carbon, as pencil lead. And it works pretty darn well at leaving marks on paper.
It leaves a brown streak.
Graphite is a crystalline form of carbon that is a soft grayish-black mineral used in pencils because of its ability to leave marks on paper. It is also used as a lubricant and in various other industrial applications.
Yes, I use the "Zoom Spout Oiler", which contains mineral oil.
hi it is algae
When a drop of oil falls on paper, the paper absorbs some of the oil while the oil spreads out and is eventually absorbed by the paper due to capillary action. The oil can leave a stain on the paper as it is absorbed.

Graphite leaves a streak on paper, as it is the material commonly found in pencils. The black mark left on paper is due to the graphite particles rubbing off onto the surface.
Graphite is a soft, black mineral that leaves a streak on paper and is used in pencils. Galena is a lead-gray mineral that is heavy and often forms cube-shaped crystals. One way to distinguish them is by conducting a streak test - graphite will leave a black streak, while galena will leave a gray streak.
Talc is commonly used in cosmetics, such as baby powder and face powder, due to its softness and ability to absorb moisture. It is also used in industrial applications for its lubricating and anti-stick properties.
White, but i have no idea why or how, it is used in white pencils replacing graphite and is used to write on black paper
It is called a streak and its purpose is to find the hardness of the mineral.
No, it does not.
No, a paper clip will not float in mineral oil because mineral oil has a higher density than a paper clip. The paper clip will sink in mineral oil.
Non-examples of a streak, in the context of geology, mineralogy, and everyday life, are situations or substances where the concept of a streak doesn't apply. A streak, in geology, refers to the color of the powder left behind when a mineral is scraped against an unglazed porcelain plate (streak plate). Here are some non-examples of streak: **Transparent Materials:** Transparent materials, such as glass or clear plastic, do not exhibit a streak. When these materials are scraped against a streak plate, they do not leave a visible colored powder or mark. **Liquids:** Liquids, by their nature, do not produce streaks when applied to a streak plate. They flow and do not leave a powder or solid residue. **Gases:** Gases, being in a gaseous state, do not produce streaks. They are not capable of leaving any visible mark on a surface. **Non-Powdered Substances:** Substances that are not in a powdered or solid form do not have streaks. Streaks are primarily associated with powdered materials. **Organic Materials:** Organic materials like wood, paper, or food do not exhibit streaks. When these materials are rubbed on a streak plate, they typically do not produce a discernible streak. **Unsaturated Solutions:** Unsaturated solutions (those in which a solute has not reached its maximum possible concentration) will not produce a streak when applied to a streak plate. Streaks are typically associated with solid materials. Streak is a property primarily used to identify minerals based on the color of the powdered residue they leave behind, and it is not applicable to substances or situations where no such residue is produced.
wipe a marker on your paper with different colros
its because there are no streak in the glass most other material leave residue behind but newspaper its the treatment that used on paper itself.
