Zusammenfassung:	The invention relates to a method for the production of a blank of a ceramic material, wherein a first ceramic material and then a second ceramic material of different compositions are filled into a mold and wherein the materials are pressed and after pressing are sintered. Thereby, a layer of the first ceramic material is filled into the mold, a first open cavity is formed in the layer, the second ceramic material is filled into the first open cavity and the materials are pressed together and are then heat-treated. Both the first ceramic material and the second ceramic material contain, or consists of, lithium silicate glass ceramic.
