Stain and Characterization firing
Once the restoration has been cleaned with steam, the Stain and Characterization firing is conducted. First, apply a thin
coat of IPS Empress Universal Glaze and Stain Liquid to the surface of the restoration to evaluate the shade of the
restoration more clearly. Subsequently, apply the stains.
The following working procedure should be observed:
– Extrude IPS Empress Universal Shade/Stains from the syringe and mix thoroughly.
– Thin the material to the desired consistency using IPS Empress Universal Glaze and Stain Liquid.
– Apply the Shade and Stains.
– Intensify the dentin shade in the cervical and central crown third using the respective Shade material.
– More intensive shades are achieved by repeated staining and firing, rather than by applying thicker layers.
– Apply individualized effects and characterizations using IPS Empress Universal Stains materials.
– After staining, the stain and characterization firing is conducted in a compatible ceramic furnace (e.g. Programat P500).
