The sooty material formed by condensation of vaporized Cn small molecules consists of mainly C60 with smaller quantity of C70 and traces of fullerenes consisting of even number of carbon atoms up to 350 or above.

Fullerenes are the only pure form of carbon because they have smooth structure without having ‘dangling’ bonds.
Fullerene are cage like molecules.
