Wash firing (foundation)
The restoration must be free of dirt and grease prior to the application of the wash. Any contamination after cleaning
must be prevented. Conduct the wash firing with IPS e.max Deep Dentin or Dentin materials (IPS e.max Ceram ZirLiner
must not be used. Given its firing temperature of 960°C/1760°F, it is exclusively suitable for use on zirconium oxide).
The following steps must be observed:
– Use the IPS e.max Ceram Build-Up Liquids allround or soft to mix the IPS e.max Ceram Gingiva, Deep Dentin or Dentin
materials.
– If a more plastic consistency is desired, IPS e.max Ceram Glaze and Stain Liquid allround or longlife can be used.
– Apply the wash in a thin coat on the veneered areas and fire.
– If the gingival portions are subsequently individualized with Gingiva layering materials, the respective areas must be
covered with IPS e.max Ceram Gingiva for the wash firing.
After wash firing Wash firing is carried out with IPS e.max Ceram Deep Dentin or Dentin on the tooth-coloured
areas and IPS e.max Ceram Gingiva on the gingival portions. Observe the firing control!
