Stain and glaze firing with IPS Empress Universal

The stain and glaze firing is carried out using IPS Empress Universal Shade, Stains, and Glaze material. Depending on the
situation, they can be conducted together or one after the other (see pages 22–24 for further details). Before the stain and
glaze firing, the restoration must be free of dirt and grease. Any contamination after cleaning must be prevented.
The following working procedure should be observed:
– Before staining and glazing, clean the restoration with ultrasound in a water bath or using the steam jet.
– To check the shade, wet the inner aspects of the restoration with IPS Empress Universal Glaze and Stain Liquid, position

the restoration on the control die, and check shade and effects.

– Extrude IPS Empress Universal Glazing Paste from the syringe and mix thoroughly.
– Thin the material to the desired consistency using IPS Empress Universal Glaze and Stain Liquid. Do not excessively dilute

the material, since this may render the glazing procedure difficult to control.

– Apply the glazing material a little thicker on areas that are not covered with layering ceramic. In this way, an even gloss

can be achieved.

– The glazing material must not come into contact with the inner aspects of the restoration.
– Avoid pooling and excessively thick glazing material layers.
– Excessively thin glazing material layers result in an unsatisfactory gloss.
– To intensify the dentin shade in the cervical and central crown third, mix the corresponding Shade material and apply it

directly into the unfired glazing material layer.

– Place veneers and anterior crowns on the honey-comb firing tray with the help of metal pins. Additionally support the

veneers with a small amount IPS Object Fix.

Firing parameters for the Stain and Glaze firing

(note the temperature control)

Optional

– If the restoration has been optimally prepolished (silky-mat gloss) in the cervical area (not covered with layering ceramic),

the glazing material can be applied in these areas only. The layering ceramic features a true-to-nature gloss without the
glazing materials.

– If a more intensive shade is required in the cervical area, we recommend conducting a separate stain firing.
