Graphite

Lampblack

Lampblack is the material collected from a cold surface held above a liquid-fuel flame, such as an oil or tallow lamp. The liquid is not completely oxidized, but individual carbon fines are caught up in the airflow and deposited on the surface. The carbon is not vaporized, merely made fine enough that the gasses rising from the flame carry it upward.

Purification

Testing

Storage

Disposal

Carbon can be disposed of directly into soil.
