In a method of doping or of coloring ceramic, glass ceramic or glass, the ceramic, the glass ceramic or the glass is provided as granular material and this granular material is brought into contact with a solution which contains metal ions and/or metal complexes. This method is used in particular in the production of shaped bodies that consist at least partly of the mentioned materials. In this way, preferably a shaped body of dental ceramic is produced.

1. A method of doping or of coloring ceramic, glass ceramic or glass, in the production of shaped bodies which comprises the ceramic, glass ceramic or glass materials, wherein the ceramic, the glass ceramic or the glass is provided as granular material and wherein the granular material is contacted
1. A method of doping or of coloring ceramic, glass ceramic or glass, in the production of shaped bodies which comprises the ceramic, glass ceramic or glass materials, wherein the ceramic, the glass ceramic or the glass is provided as granular material and wherein the granular material is contacted with a solution which comprises metal ions and/or metal complexes and the solution penetrates pores and/or capillaries present in the granular material. 2. The method according to claim 1, wherein the granular material is sprayed with the solution. 3. The method according to claim 1, wherein the granular material treated with the solution is dried at a temperature <100° C. 4. The method according to claim 1 wherein the granular material is moved during the contacting and/or during drying. 5. The method according to claim 1, wherein the solution comprises metal ions or metal complexes of one or more rare earth elements. 6. The method according to claim 5, wherein the solution comprises metal ions or metal complexes of at least one of iron, chromium, copper, yttrium, praseodymium, cobalt, nickel, manganese, erbium or cerium. 7. The method according to claim 1, wherein the solution comprises at least one polar solvent, wherein the polar solvent is preferably water or at least one aliphatic alcohol. 8. The method according to claim 1, wherein the metal ions or metal complexes are present in the solution in a concentration of between 0.01 wt.-% and 70 wt. 9. The method according to claim 1, wherein the granular material is further processed to form a shaped body. 10. The method according to claim 1, wherein the material is a ceramic based on zirconium oxide or aluminium oxide. 11. The method according to claim 10, wherein the ceramic is a dental ceramic. 12. A ceramic, glass ceramic or glass, producable or produced by the method according to claim 1. 13. A dental shaped body, produced from the ceramic, the glass ceramic or the glass according to claim 12. 14. The dental shaped body according to claim 13, comprising an unsintered or not finally-sintered blank for producing an all-ceramic dental prostheses. 15. A dental prosthesis produced from the shaped body according to claim 13. 16. The method according to claim 4, wherein the granular material is moved by circulating or stirring during the contacting. 17. The method according to claim 4, wherein contacting comprises spraying. 18. The method according to claim 5, wherein the rare earth elements comprise the lanthanoids, or the sub-group elements of the periodic table of the elements. 19. The method according to claim 7, wherein the at least one polar solvent comprises water or at least one aliphatic alcohol. 20. The method according to claim 8, wherein the metal ions or metal complexes are present in the solution in a concentration of between 0.1 wt.-% and 50 wt.-%. 21. The method according to claim 9, wherein the granular material is further processed by at least one pressing step after the contacting, and optionally after drying. 22. The method according to claim 21, wherein the at least one pressing step comprises dry pressing. 23. The method according to claim 11, wherein the dental ceramic comprises zirconium oxide, yttrium oxide, hafnium oxide and/or aluminium oxide and optionally further oxides.
