Abstract
A method for the production of a polychromatic and/or spatially polychromatic or a monochrome colored ceramic body, in particular a dentine ceramic blank, which is dyed in this way, wherein in order to control a targeted distribution of color pigments (101, 102) within a porous ceramic (100), in a first step, which is a loading step (3c), the ceramic (100) is loaded with a color pigment solution (104). In a second step, which is a distribution control step (4d), the distribution of the color pigments (101, 102) within the ceramic (100) is controlled by controlling one or more environmental parameters (106) in an environment (108) and/or the pressure and/or temperature.

A method for manufacturing a polychromic or spatially polychromic or a monochrome colored ceramic body colored in this method, for management of a targeted distribution of color pigments (101, 102) within a porous ceramic (100) in a first step, which is a loading step (3c), the ceramic (100) is loaded with a color pigment solution (104), and in a second step, which is a distribution management step (4d), the distribution of the color pigments (101, 102) is managed inside the ceramic (100) by setting one or several environmental parameters (106) in an environment (108), characterized in that the distribution of the color pigments (101, 102) within the porous ceramic (100) is affected by a convection flow, whereby the direction of the flow and the velocity of the flow are managed by targeted creation of environmental parameter gradients (110) relative to various surfaces (114, 116) of the porous ceramic (100).
