Apply wash in a thin layer.
Make sure to smooth out any roughness on the metal surface.
Subsequently, the restoration is fired using the stipulated firing parameters.

Extrude opaquer from the syringe and mix thoroughly.
Apply the first opaquer layer (wash) thinly using a brush.
Unlike with powder/liquid
systems, the opaquer paste
must not be excessively
mixed with opaquer liquid.
1 st opaquer firing (wash firing)
Extrude the desired amount of the ready-to-use opaquer
paste from the syringe and mix thoroughly. Unlike with
powder/liquid systems, the opaquer paste must not be
excessively mixed with opaquer liquid. The opaquer liquid
is exclusively used to adjust the consistency of the paste
opaquer and to rewet dried opaquer that has been used
several times. Caution: Do not excessively dilute the paste
opaquer with the opaquer liquid. Do not dilute the material
with water.
Apply the first opaquer layer (wash) thinly using a brush.
Smooth out any roughness on the metal surface since the
wash is the most important connection between the metal
oxide surface and the ceramic.
