Soot

Soot is a black, powdery residue composed primarily of carbon particles, formed as a byproduct of incomplete combustion of organic materials such as wood, coal, oil, or gas. It typically appears as a fine, flaky substance that adheres to surfaces and can be difficult to remove. Its formation is often linked to inefficient burning processes and can be an indicator of poor ventilation. Soot's composition can vary depending on the fuel source and combustion conditions, including hydrocarbons, ash, and other compounds. It's a significant contributor to air pollution and can pose health risks if inhaled.
