Wash firing
Conduct the wash firing using the IPS Empress Esthetic Veneer Wash Pastes. Apply the wash pastes thinly and cover the
entire restoration. The IPS Empress Esthetic Veneer Wash Paste neutral is always applied first on the restoration and
enables a homogenous bond to the IPS Empress Esthetic material. Subsequently, the reduced restorations are individually
characterized, if required, using the Standard Wash Pastes and Wash Paste Modifiers. The wash pastes must be fired
separately. If required, the pastes can be slightly diluted using IPS Empress Universal Glaze and Stain Liquid.
Place the objects on the honey-comb firing tray by using IPS Object Fix and fire.
