Compact Updraft Gas Raku Kiln — Hand-Crank Lift Chamber, Cone 10
Max Temp
Cone 10 · 2350°F
Olympic Raku gas kilns bisque, high fire (cone 10), reduce, and raku — all in one updraft kiln. They're built from durable firebrick and use venturi burner systems for even, controllable firings on either natural gas or propane.
What makes a raku kiln different is the hand-crank lift chamber: a turn of the winch raises the firing chamber straight up, giving you fast, easy access to red-hot ware while keeping the heat trapped in the kiln and away from you. The 18 Raku is the compact model in the line — ideal for individual potters, demonstrations, and smaller raku loads.
Included with every order
Frame welded to the firing chamber, venturi burner system with multi-point ignition and thermocouple safety shut-off, peephole plugs, a brick for covering the porthole during reduction, full instruction manual, and a 1-year limited kiln warranty through Olympic.
Popular add-ons include a digital pyrometer, an electronic high-limit controller, castors, a low-pressure propane regulator, raku tongs, and gloves. Give us a call and we'll help you spec the right setup.
A note on lead time: Olympic kilns are made-to-order at their Flowery Branch, Georgia facility. Give us a call before ordering and we'll confirm current production estimates.
