Step 2 – Application of the glazing material:
– Extrude IPS Empress Universal Glaze from the syringe and thin the material to the desired consistency using IPS Empress
Universal Glaze and Stain Liquid.
– Apply the glazing material on the entire outer surfaces of the restoration.
– The glazing material must not come into contact with the inner aspects of the restoration.
– Too thin glazing material layers result in an unsatisfactory gloss.
– Avoid pooling and too thick glazing material layers.

Completed IPS Empress Esthetic restorations, stained and glazed.
Evenly apply IPS Empress Universal Glaze on the entire outer surfaces of the restoration. Place the restorations on the honey-comb firing tray using IPS Object Fix
and metal pins and fire.
After applying the glazing material, the glaze firing is conducted in a compatible ceramic furnace (e.g. Programat P500).
The following points should be observed when placing the restoration in the furnace and setting the firing parameters:
– Place the restorations on the metal pins using a small amount of IPS Object Fix and position them on the honey-comb
firing tray .
– As an alternative, the restorations can be supported with a firing pillow. Due to their lower position in the firing
chamber, the restorations are exposed to less heat. Therefore, in order to achieve the desired gloss, the holding time
must be extended to up to 2 minutes.
