Wash firing (foundation)
The restoration must be free of dirt and grease before the wash firing is done. Any contamination after cleaning must be
prevented. Wash firing is carried out with IPS e.max Ceram Incisal and Impulse materials or Shades and Essences.
Option A: Powder
Conduct the wash firing with the required IPS e.max
Ceram Incisal and/or Impulse materials. Use the IPS e.max
Ceram Build-Up Liquids allround or soft to mix the
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 entire frame-
work.
Option B: Glaze, Shades and Essence
To enhance the in-depth chroma effect or for individualized
internal characterizations, the wash firing can be
conducted with Glaze, Shades and Essence. Mix the paste
or powder with the IPS e.max Ceram Glaze and Stain
Liquids allround or longlife to the desired consistency.
Apply the wash in a thin coat on the entire framework.

Layering materials must not be applied on unfired wash layers (powders and pastes), since this will result in
a delamination of the layering ceramic. The wash (foundation) must be fired before the actual layering
procedure is started.
