(13) Cooling stage: Cooling in multiple stages results in
a gradual release of tension within the ceramic material. If
selected under (2) the progression of cooling stages will
begin immediately after firing (12).
• Stage 0 - Firing platform immediately moves to its
bottom position, no cooling
• Stage 1 – Firing object is lowered by approx. 7 cm
• Stage 2 – Firing object is lowered by approx. 5 cm
• Stage 3 – Firing object remains in the chamber
The starting point in each case is the base temperature
(pre-set to 400 °C). Once the program has been started,
the unit pre-heats to the pre-set pre-heating tempera-
ture (e.g. 575 °C) (see "Pre-heating temp start"). During
the drying phase (8), the firing chamber is gradually
closed. Closure will be completed at the end of the drying
phase, as the pre-heating temperature reaches its
pre-set value. The program then waits out the pre-set
pre-heating time (9) and starts the vacuum pump.
Once the full vacuum has been attained, this is followed
by the heating phase at the pre-set heating rate (4)
(e.g. 120 °C/minute). Once the firing temperature (6)
(e.g. 1,200 °C) has been reached, the program enters
the firing phase (12) (holding phase) during which the
vacuum pump will be active for the pre-set vacuum
time (11). The end of the firing phrase is followed by the
pre-set cooling stages (13).
