A process for the production of colored structures in a glass and thereby manufactured glass

The invention relates to a process for the production of colored structures in glass, in which existing or glass introduced with the procedure ions at least one metal is reduced by localized energy input, especially in the focus of a laser radiation and transferred to a localized accumulation of metal particles, the a local, typical for the used metal discoloration causing a plurality of localized areas are produced with a monochrome output color for producing multicolored structures in a first step, which differ in gradations of the same color and in a second step by means of a global or local energy input into induced the ranges of the output color dependent Partikelbildung- and / or -wachstumsprozesse so that regions with different initial coloration receive a different color. The invention further relates to a glass element comprising a pictorial representation having regions of different colors, produced by the method.
