IMPORTANT:
No flux must touch the elements. Element life would dramatically
be reduced.
IMPORTANT
: User must always remove the crucibles from the instrument
before weighing powder components, and make sure that the crucible and mold
external walls are clean before re-installing them in their heaters.
Crucible
installation
Once the crucible is filled with the proper components, it can be installed in the
crucible heater.
To install the crucible, rotate the locking bar upwards until it rests to the right.
Gently insert the crucible into the heater cavity and re-close the locking bar.
IMPORTANT
: Installing the crucible requires that the locking bar be fully
closed. Checking this before each fusion is required to ensure safe operation.
Mold
installation
After the crucible has been installed, one must place a mold to receive the molten
material.
IMPORTANT
: Forgetting to install the mold will cause the crucibles to pour the
hot molten glass onto the instrument, possibly damaging it.
A general
fusion
Here are the steps required to perform a fusion on the K1 Prime fluxer.
1.
Turn the instrument on by flipping the rocker switch at the back of the
instrument. The main screen appears when booting is complete.
2.
Check crucible and mold heaters for possible flux spills from a previous fusion.
(See page 39,
, for details.) If heaters’ interiors look vitreous and
dirty, clean them immediately; do not start a fusion process with dirty holders,
as this could damage the instrument.
3.
Select the desired fusion program, by clicking on the left and right arrows that
flank the current program name.
4.
In the platinum crucible, weigh the required amount of flux.
5.
Add the sample by weighing it directly into the crucible on top of the flux. Mix
if no solid oxidizer is to be used.
6.
Prepare solid oxidation, if required.
6.1
Add a suitable solid oxidizer (generally, a nitrate or carbonate) in the
crucibles.
6.2
Mix thoroughly with the sample. (Try to leave the bottom layer of flux
untouched.)
