For fine divestment, only 2 bar (30 psi) pressure is applied.
When divesting the object, blast from the direction indicated in the schematic at the top.
Press result after pressing at too low a temperature.
If the object is pressed at too high a temperature, a substantial reaction layer forms that is
difficult to remove. If the reaction layer is not completely removed, the bond to the layering
material is impaired.
If the temperature of the furnace has been set correctly, the pressed objects exhibit only a
thin reaction layer that can be easily removed, following the directions given below.
Rough divestment is carried out with polishing jet medium (Ivoclar Vivadent) at 4 bar (60 psi) pressure.
