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.
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.
Quick Overview
Olympic Raku & Torchbearer
gas kilns bisque, high fire (cone 10), reduce, and raku. Olympic updraft
gas kilns are constructed from durable firebrick and are equipped with
venturi burner systems to ensure even temperature firings.
Olympic Raku gas kilns are especially designed for raku work by
retaining heat in the firing chamber when elevated by the turn of a hand
winch, allowing easy access, while trapping the heat in the kiln and
away from the operator.
Today potters can create the ancient Japanese technique, raku and its
unique beauty, metallic luster and colors with an Olympic Raku kiln.
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.

Models can be purchase with burners only or with the option of a burner
system which includes an ignition to light multiple burners at one
point, maintain the flame on each burner and re-ignite any burner that
may extinguish. The thermocouple safety shut-off will stop the gas flow
if the flame is lost entirely.
