Glasses with colored structures and methods for their preparation

Glasses with colored structures composed of non-limited of the glass surface volume elements, wherein the structures are prepared by heating of volume elements of the glass in the focus area of ​​a laser radiation, which is so weakly absorbed, that all required positions in the glass can be reached and whose absorption only in the focus area results in a sufficiently strong temperature increase to form from ions contained in the glass of such metals which color glasses in the form of submicroscopic particles, metal particles.
