Ball lightning plasma and plasma arc formation during the microwave heating of carbons

Photographic evidence of plasma formation when different carbon materials are subjected to microwave heating is presented. Two different kinds of plasmas are observed: ball lightning and arc discharge plasmas. The intensity of the plasmas in the less ordered carbon was significantly higher at the beginning of the process.
