In a ceramic tool and associated method of making it, a ceramic base is infused with a material. The material is preferably a metal based compound advantageously chrome oxide. The chemical formulation of the material can be modified in order to optimize the rate of material deposition and the desired surface performance. The depth of the infusion is advantageously 0.1 to 1mm preferably 0.25mm. The moulding surface of the tool may be treated to vapour or oat blasting. The resultant tool has a longer life and may be used without a release agent. |
