Glaze firing
The following basic rule applies: The longer the
hold time (H), the higher the gloss. Depending on
the desired gloss, the holding time is 0.5–1 min.
Method 1
Glaze firing without glazing material
Slightly wet the restoration using IPS d.SIGN Glaze and Stain
liquid and apply shade adjustments and/or individualized
characterizations. Position the restoration on the honey-
combed firing try and fire.
If the glaze firing is conducted without glazing materials, the
stains should not cover too large an area.
After firing, the gloss of the restoration may be adjusted to
meet the patient's individual requirements by polishing with
rubber polishers, felt wheels, and pumice.
For the glaze firing, you have several options, depending on
the desired working procedure:
– Glaze firing without IPS d.SIGN Glazing material for a
true-to-nature, silky-mat gloss.
– Glaze firing with IPS d.SIGN Glazing material for a high
gloss.
– Glaze firing without IPS d.SIGN Glazing material and
simultaneous adjustment of the ceramic shoulder using
IPS d.SIGN Margin Add-On (see page 47).
– Glaze firing with IPS d.SIGN Glazing material and
simultaneous adjustment of the ceramic shoulder using
IPS d.SIGN Margin Add-On (see page 47).
