Authorized Olympic dealer · full factory warranty
Brand new and shipped direct from Olympic Kilns, so it carries Olympic's full factory warranty. If something goes wrong, call us and we handle the claim with the factory for you.
Warranty terms are in the Warranty and support section below.
Returns: request within 15 days, unused
Because kilns are heavy and often built to order, returns are limited, so we'd rather help you pick the right one up front:
- Ask within 15 days of purchase or 2 days after delivery, whichever comes first. We issue a return authorization (RA).
- It must be new, unused (beyond the factory test fire) and in its original packaging.
- A restocking fee of at least 25% applies, up to 50% on custom, 3-phase or made-to-order units. Return freight is on the buyer unless we made an error.
- Damaged in transit? Note it on the delivery receipt, send us photos and we'll help with the freight claim.
Will it work in my space? Power check
Not included: kiln shelves and posts, low-pressure regulator, vent hood and castors (optional, sold separately). Gas hookup by a qualified installer: propane 11″ w.c. / natural gas 7″ w.c.
Most 240V kilns need their own circuit and the matching outlet, installed by an electrician. Homes are usually 240V; schools and commercial buildings are often 208V, so pick the voltage that matches your panel.
Send us a photo of your breaker panel or outlet and we'll confirm before your kiln is built: 470-264-3563 (call or text).

Olympic 2327G Updraft Gas Kiln
The Olympic 2327G is a professional updraft gas kiln designed for bisque, high-fire, reduction, and raku firing. With a 23.375-inch interior diameter and 27-inch height, this kiln provides 6.9 cubic feet of firing capacity and reaches temperatures up to Cone 10 (2350°F). Convertible between natural gas and propane operation, the 2327G delivers consistent results for potters and ceramicists working in traditional reduction atmospheres.

What’s included
The kiln, built in rings on its frameThe chamber is built in rings on its steel frame with the burner system already mounted and plumbed to it. Olympic publishes no ready-to-fire statement for the Torchbearer line, so we confirm the delivered state with the factory before your order goes in.
Burners with ignition systemOlympic prices this as a single line and it is the whole firing system: the burners, orifices sized for the gas you tell us you run, the manifold with its gas valve, the pilot bar or pilot ring, a magnetic valve with a thermocouple safety shut-off, and the ignition. It arrives mounted to the kiln, not boxed loose.
No controller and no pyrometerOlympic's gas kilns ship with no digital controller and no temperature readout at all, so you fire by cones. The High Limit Controller is a $1,600 option and a pyrometer is a separate purchase, so add one at order time if you want a reading.
The frame it stands onThe kiln body comes on its own steel frame and legs, so there is no separate stand to buy or build.
The operating manual and a one-year warrantyOlympic's printed gas kiln operating manual travels with the kiln. Olympic's limited warranty runs two years, cut to one year on any kiln rated at cone 10, and every Olympic gas kiln is rated at cone 10, so one year. Register with Olympic within 30 days of delivery.
Not included: the gas hook-upThe low pressure regulator is a paid option, $175 on the 18-inch and $275 on the 23-inch and 28-inch kilns. The 3/4-inch gas hard line, the hose and the fittings back to your meter or tank are your plumber's work and are not supplied.
Not included: damper and vent hoodNo damper ships with the kiln. Olympic's manual has you cover the flue with a brick or a kiln shelf that you supply. The vent hood is a separate item at $1,700 to $1,750 and is not included.
Not included: furniture and accessoriesNo kiln furniture. Every gas line has its own separately priced furniture kit and shelves and posts are priced one by one. Raku tongs, gloves, stilts and kiln wash are separate items too.

Common questions
Can the 2327G operate on both natural gas and propane?
Yes, the Olympic 2327G is convertible between natural gas and propane operation. The kiln is typically shipped configured for natural gas, but can be converted to propane using the appropriate orifice and regulator adjustments. Both fuel types deliver 150,000 BTU/hour at maximum output. If you need propane configuration from the factory or conversion components, contact us before ordering.
What installation requirements does this gas kiln have?
The 2327G requires professional installation by a qualified gas technician or plumber familiar with local building codes. You'll need adequate gas line sizing (typically 1-inch for natural gas, 3/4-inch for propane), proper ventilation with an exhaust hood or chimney system, non-combustible flooring rated for 850+ lbs, and clearances from combustible materials per manufacturer specifications. Always obtain necessary permits and inspections before operating the kiln.
Does this kiln include kiln furniture?
No, kiln shelves and posts are sold separately. The 23.375-inch interior diameter accommodates round shelves up to 22 inches or half-shelves for flexible stacking configurations. We recommend ordering a furniture kit sized specifically for the 2327G when you purchase the kiln, as you'll need shelves and posts rated for cone 10 reduction firing before your first load.
What type of atmosphere control does the updraft design provide?
The updraft burner configuration on the 2327G delivers excellent reduction capabilities through bottom-fired heat circulation. The adjustable damper system allows precise control over oxidation and reduction atmospheres throughout the firing cycle. This design is particularly effective for traditional reduction glazes, carbon trap techniques, and raku firing where atmosphere control is critical to achieving desired surface effects.
How is the warranty validated?
Olympic Kilns provides a one-year limited warranty that must be registered within 30 days of delivery. The warranty is only valid when the kiln is purchased through an authorized Olympic dealer like Peach State Pottery and properly installed according to manufacturer specifications. Keep your proof of purchase and installation documentation, as warranty claims require verification of authorized purchase and proper setup.
