Why is the IPS e.max Ceram ZirLiner powder green and how should it be applied?
Since zirconium oxide is white and, therefore, shows a poor contrast to tooth-coloured and/or white powders, the IPS e.max ZirLiner was given an identification colour to render its application more simple and efficient. The IPS e.max Ceram ZirLiner consists of a very fine powder and appears somewhat thick due to the dense packing of the grains. Make sure that the material is applied in an even, greenish coat. If the shade is too pale, the layer is too thin. After firing, however, the ZirLiner demonstrates a layer thickness of approximately 0.1 mm.
