| The FireFly is a manually controlled kiln. The black
knob you see on the control box is called an
Infinite Control Switch that works like the knob
on your oven....the more you turn it up, the hotter
it gets. A pyrometer is used to measure the
temperature inside the kiln.
|
|
|
The pyrometer is inserted into the kiln through a portal
in the back. The pyrometer is connected to a battery
operated digital display that gives a constant
readout of the interior temperature.
It's important to understand how this type
of switch works because it requires the user
to monitor the firing from beginning to end.
As the kiln heats, you will adjust the knob
until your target temperature is reached,
and then monitor it for
accuracy through the firing,
adjusting as needed.
For those who do not
wish to devote the
attention required to
operate a manually
controlled kiln,
we suggest the
SC2 model which is
a digitally controlled kiln. |

The pyrometer measures in degrees F up to 1999F. A high-temperature pyrometer can be ordered for firings over 1900F, which for most metal clay artists will not be ncessary since we usually fire no more than 1650F.

The pyrometer measures in degrees F up to 1999F. If you fire hotter than 1999 F, a special high-temperature pyrometer can be ordered. |

The FireFly is made of durable 2 1/2" thick
insulating firebrick that stores heat
for slow cooling and safe annealing
of all glass projects.
Place the FireFly on any heat-proof
surface and plug into a 120V outlet.
Sturdy hinged lid opens from the top.
We recommend 2 kiln shelves, 1 set of
1" kiln posts, a bead firing dish
with vermiculite, and a fiber blanket
as a great firing accessory kit.
Dropped, recessed grooves
protect the replaceable
heating elements for
longer life. Wires are
fastened to the elements
with heat-dissipating
connectors refined and
proven over many
years in Paragon kilns.
Elements are coiled from
the finest high-temperature
wire available. |

The hinged lid is self-adjusting to compensate for expansion at high temperatures. The hinge includes a stop that holds the lid open and out of the way. Lift the lid with a handle on the front or a separate handle on the side. A stainless steel heat shield inside the switch box protects wiring from contact with the case. Costly nickel-plated copper wiring is covered with high temperature glass-braided insulation. Louvers on the top, side, and bottom of the switch box circulate air for the long life of the electrical components while keeping dust inside the box to a minimum.

The Infinite Control Switch This manual-fire kiln operates without electronics or timers. It uses the infinite control switch to adjust heat output. These switches have been proven reliable over many years of kiln production. The infinite control switch cycles on and off through a bi-metallic timer. The higher the switch setting, the longer the heating elements stay on during each cycle. When the switch is turned to High, the elements stay on continuously. For most firings the switch is first set on LOW, then turned up to the target temperature. You will need to be prepared to monitor the entire firing with this type of control.
