Abstract
The present invention relates to a method and a device for crushing glass bodies, in which the glass body is arranged in a microwave field so that the said glass body is crushed on account of the resulting thermal stresses. In addition, a local plasma which results in further thermal stresses, is produced on the surface of the glass body Since the glass body to be crushed does not come into contact with crushing means, for example rollers or the like, the pieces of broken glass cannot be contaminated by abrasion particles of the crushing means. The plasma permits a rapid and economic crushing of the glass bodies.
