Olympic Kilns 23 Raku Updraft Gas Kiln
The Olympic 23 Raku is an updraft gas kiln engineered specifically for raku firing techniques that produce dramatic metallic lusters and crackle glazes. This 23.375-inch diameter kiln fires to Cone 10 on either natural gas or propane, with a specialized burner system designed for the rapid heating and controlled atmosphere required for successful raku work. Built with durable refractory materials and a convertible gas system, this kiln delivers consistent high-temperature performance for both traditional raku and alternative firing methods.

Common questions
Can this kiln run on both natural gas and propane?
Yes. The Olympic 23 Raku is convertible between natural gas and propane. The kiln can be factory-configured for either fuel type, and conversion kits are available if you need to switch fuel sources. Natural gas typically provides more consistent BTU delivery for long firing sessions, while propane offers greater portability. Contact us to specify your preferred fuel type when ordering.
What are the gas supply requirements for this kiln?
For natural gas operation, you'll need a dedicated gas line with adequate pressure (typically 7-14 inches water column) and sufficient BTU capacity to reach Cone 10 temperatures. For propane, a standard tank with appropriate regulator is required. The exact BTU rating and supply line sizing should be determined by a licensed gas technician based on your facility's specifications. All gas installations must comply with local codes and regulations.
Does this kiln come with kiln furniture?
No, kiln furniture (shelves and posts) is sold separately. Raku firing often requires specialized furniture that can withstand rapid temperature changes and thermal shock. We recommend high-temperature shelves rated for Cone 10 and sized to fit the 23.375″ diameter chamber. Contact us for furniture kit recommendations specific to raku firing techniques.
What installation and ventilation requirements should I plan for?
The Olympic 23 Raku requires outdoor installation or a well-ventilated indoor space with proper exhaust ventilation, as gas kilns produce combustion byproducts. You'll need clearance from combustible materials as specified in the owner's manual, typically 18-36 inches on all sides. The kiln should be installed on a non-combustible surface with the included stand. A licensed gas technician must perform the gas connection, and installation must meet all local fire and building codes.
How is the one-year warranty activated?
Register your kiln with Olympic Kilns within 30 days of delivery to activate the one-year limited warranty. The warranty covers manufacturing defects in materials and workmanship but does not cover damage from improper installation, misuse, or normal wear components like burner parts. Warranty service is only valid when the kiln is purchased through an authorized Olympic dealer like Peach State Pottery.
