By reducing costs and time of the production process and by introducing significant improvements in technological processes, laser fusing of colour ceramic agents with ceramic or glass products arouses great interest, thereby substituting the typical process of furnace firing for decoration of small series of products. Glass substrate of a decoration allows use of two configurations of the optical scheme in the technological process – laser irradiation from the side of fused ceramic layer as well as from the side of glass substrate. Presented results are mainly related to experimental determination of utility features and advantages of both solutions. Full Text: PDF References J.M.
