right|thumb|One can produce a tar-like substance from corn stalks by heating them in a microwave oven. This process is known as pyrolysis. Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from carbon-rich materials such as coal, wood, petroleum, peat, and other organic matter.

AI overview

Tar is a dark, thick liquid made up of hydrocarbons and carbon that's produced by heating carbon-rich materials like coal, wood, and peat in a process called destructive distillation. It has been historically important as a useful material derived from various organic sources, and can even be made from unexpected materials like corn stalks using heat.
