Abstract
Particles colored with at least one colorant, where the colored glass particles are glass platelets with an average diameter of 1 to 500 μm and the colorants at least include at least one of metallic nanoparticles and metal oxides. The glass platelets are planar and the colorants are present in a concentration from 1% to 55% by weight, based on the total weight of the colored glass platelets. The disclosure further relates to a method to a method for producing the colored glass particles and to the use thereof.
