The present invention relates to a blank for dental purposes which has a first and a second layer which, independently of each other, are based on glass, glass-ceramic or ceramic, wherein the first layer and the second layer differ in colour and form a boundary surface, wherein the boundary surface runs obliquely.

Multi-coloured blank for dental purposes

A process for producing a glazed ceramic body, in which a glazing material is applied to a non-densely sintered substrate material and the substrate material and the glazing material are subjected to a heat treatment in order to obtain the glazed body.
