The Pause button is used to temporarily “freeze” the
ongoing fusion.
In pause mode, timers are suspended, and the current
furnace temperature is maintained. Any ongoing motor
motion will be continued or completed. This can be useful
when some extra time is required to complete an oxidation
or dissolution reaction, for example.
Press the Pause button again to resume normal operation.
This icon represents the ramping speed to reach the
programmed crucible temperature. Default value is “Fast”
(i.e. the crucible heats at full power), but it is possible to
slowly ramp up the temperatures, at rates expressed in
°C/minute.
This cluster represents the elapsed time (mm : ss) since
the requested temperature is attained, as well as the
currently-running step number (in red).

, for more
information on this topic.
The Stop button, as the name implies, is used to halt an
ongoing fusion process, stopping all motors.
This can be used when one realizes that the crucibles or
molds are not properly prepared, or in case of emergency,
for example.
Pressing Stop again will cancel the ongoing program and
reset the instrument.
Pressing Start instead will resume the fusion program.
The right
ingredients
From the preceding paragraphs, we already know how to launch a fusion
program. There are, however, a few other things than one should know to obtain
a perfect disk. These include:
1.
properly preparing the sample for the fusion,
2.
selecting the appropriate flux blend for the sample type,
3.
determining the total mass in the crucible from the mold capacity,
4.
estimating the flux-to-sample ratio,
5.
using the appropriate additives, and
6.
mixing the components together.
