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. Conduct the wash firing, e.g. with Transpa Incisal, Impulse or Shades and Essence.
Option A: Powder
With ideal space, conduct the wash firing with the
required IPS e.max Ceram Transpa Incisal and/or Impulse
material. Use the IPS e.max Ceram Build-Up Liquids all-
round or soft to mix the materials. If a more plastic
consistency is desired, IPS e.max Ceram Glaze and Stain
Liquid allround of longlife can be used. Apply the wash in
a thin coat on the reduced (cut-back) areas and fire using
the stipulated firing parameters.
Option B: Paste
With limited space or to enhance the in-depth chroma
effect, the wash firing can be conducted with IPS e.max
Ceram 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 and fire using the stipulated
firing parameters.
Apply the wash using Transpa Incisal and/or
Impulse materials…

Firing parameters for the Wash firing (foundation firing)
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.
