Shelves and posts sized for this kiln's chamber. They hold your work in layers so you can fill the kiln on every firing.
Who needs it: Everyone. Nothing ships inside the kiln crate, so without shelves and posts you can't load or fire the kiln.
Skip it if you already own shelves and posts that fit this exact chamber size.

A downdraft vent that mounts under the kiln and pulls fumes, smell and moisture out through a small duct to the outside.
Who needs it: Anyone firing indoors: garage, basement, classroom or home studio. It also evens out temperatures top to bottom and cuts the corrosive fumes that wear on elements and metal parts.
Skip it if your kiln sits in a detached, well-ventilated building with an overhead hood.

Who needs it: Studios running two kilns that already own (or are buying) a VentMaster.

Extra duct length for the VentMaster vent.
Who needs it: Kilns that will sit farther from an outside wall or window than the vent's standard hose reaches.
Skip it if your kiln will sit close to the wall where the vent exits.

A digital controller in its own wall-mounted box. It runs the kiln through a power cord, away from the kiln's heat.
Who needs it: Kilns with a manual or worn-out controller, or studios that want a different interface. Pick the voltage and amperage that match your kiln.
Skip it if this kiln already has a programmable controller built in. Most buyers do not need a second one; ask us about the factory touchscreen upgrade instead.

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
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).
