the syringe and dilute it to the desired consistency using the
Universal Glaze and Stain Liquid and mix. There are
14 IPS Empress Universal Stains available for individualized
characterizations.
Do not mix the IPS Empress Universal Shades and
Stains in paste form with the powder materials.
Moreover, they must not be applied during
layering, i.e. between unfired dentin and incisal materials.
Applying the stains in a thin layer.
Before starting the staining procedure, make sure
the restoration is free of dirt and grease. A
roughened surface is favourable.
