Olympic Raku and Torchbearer Gas Fired Kilns

Raku
is an ancient Japanese technique that has been rediscovered by modern
potters who appreciate its unique beauty and metallic luster and
colors. The raku process involves reducing (starving the oxygen) the
glazed raku pottery in combustible materials such as leaves, sawdust,
newspaper, etc. When the pieces are ready to take out of the kiln, they
are placed in galvanized trash containers with combustible materials
and covered. Once the pieces are cooled down, they are removed from the
containers,
washed and reveal the rich warm effects of raku.
Olympic Raku Kilns:
What
every potter’s been waiting for ... a kiln that bisques, high fires
(Cone 10), reduces, and best of all – is especially designed for raku
work. It’s clean, easy, efficient and effortless.
The Olympic Raku
kilns are constructed from durable firebrick and are available in three
popular sizes. The firing chamber can be smoothly elevated by the turn
of a hand winch, allowing easy access, while trapping the heat in the
kiln and away from the operator. All Olympic Rakus are equipped with a
venturi burner system to ensure even temperature firings.
The Olympic Raku kiln comes with a one-year warranty. Shelving, castors, and a pyrometer are available options.
Olympic Torchbearer Toploading Gas Kilns:
Olympic
Torchbearer Gas Kilns will fire to Cone 10/2350° Fusing natural gas or
propane and are well suited for bisque, oxidation, and reduction
firing.
The Olympic Torchbearer kilns are top
loading, stackable gas kilns. These kilns
are portable and rings can be added for
additional depth without decreasing temperature
range.
The
Olympic Torchbearers use the same high-quality multiple venturi burner
system configuration as the commercial Olympic DownDraft kilns. The
multiple burner confi gurations provide even heating characteristics,
fast controllable firing times, and economical operation. Olympic’s
portable gas kilns offer many advantages such as low initial cost,
convenient movement, simple maintenance, and use in situations where
space does not permit installation of large permanent kilns.
All
Torchbearer Kilns are built in rings and may be easily enlarged with
additional rings to conform exactly to your firing needs. (Adding kiln
rings will not decrease firingtemperatures as in an electric kiln).
OPTIONS: Pyrometer, Kiln Sitter and Limit Timer.
Note: The prices shown for the Torchbearer and Raku kilns here include the Ignition Ring with Thermocouple Safety Shut-off
which
adds a high degree of safety. We can supply these kilns without the
Ignition ring but we feel that for safety's sake these should always be
installed.
The ignition system is used to:
■ Light the multiple burner system from
one point
■ Maintain the flame on each burner
■ Re-ignite any burner that may
extinguish
The thermocouple safety shut-off will stop the gas flow if the flame is lost entirely.
Burner Systems: The burners are included with these kilns: 23" or 28"
