Plasmas are thermally or electrically charged gas mixtures of electrons, ions and atoms also called "fourth aggregate state", differentiating between "hot" plasmas, e.g. lightning in which all the particles have a high temperature, and "cold" plasmas, which predominantly find use in technical applications and permit treating temperature-sensitive surfaces. Whether in manufacturing mobile phone or printing plastics, these so-called unbalanced plasmas have become indispensable. But are they also relevant for restoration?
