1 st shoulder firing
A porcelain shoulder can be fabricated on the metal frame-
work after the opaquer firing if the necessary space has been
provided during finishing. First, isolate the gypsum die with
IPS Margin Sealer. Once this material has dried, apply
IPS Ceramic Separating Liquid.
After that, generously apply the IPS d.SIGN Margin material
in the desired tooth shade in the cervical area in the shape of
a drop (i.e. the outer surface of the ceramic material is given
a convex design) and dry. For aesthetically exacting work,
four intensive Margin materials are available. They may either
be mixed or applied alone.

IPS d.SIGN Opaquer F
For more in-depth fluorescence.
As a 3 rd firing:
Apply the IPS d.SIGN Opaquer F as a very thin, third opaquer
layer and fire separately.
Important: dilute the paste opaquer with an adequate
amount of IPS d.SIGN Opaquer Liquid.
Mix with current IPS d.SIGN opaquers:
Mix up to 20 % of Opaquer F with the conventional
IPS d.SIGN Opaquer before the second layer is applied.
