When it ships & how it's delivered · freight to your door

Evenheat builds most kilns to order once your order is placed. We email your confirmed ship date and tracking.

  • The freight carrier calls you to book a delivery window.
  • Delivery is curbside with a liftgate. Have a helper or hand truck to move it inside.
  • Check the crate before you sign. Note any damage on the receipt and send us photos.

Authorized Evenheat dealer · full factory warranty

Brand new and shipped direct from Evenheat, so it carries Evenheat'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.

Read the full return policy

Will it work in my space? Power check

Not included: blade fixture, loud alarm, tongs, gloves and foil (sold separately). Requires a 240V single-phase circuit (15A, 3600W) with a NEMA 6-20 receptacle.

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).

Common questions
Why is the side-element-only design important for knife making?Traditional ovens with rear heating elements create hot spots at the back wall, which can overheat the tips of long blades and cause uneven heat treatment or warping. The LB Series eliminates the rear element entirely, using only side elements to deliver perfectly uniform temperature from front to back across the full 27-inch chamber length. This means you can position blades anywhere in the chamber with confidence.
What types of steel can I heat treat in the LB 27?The 2200°F maximum temperature covers the vast majority of steels used by knife makers, including popular choices like 1095, 5160, O1, CPM-154, AEB-L, and most stainless steels. High-speed steels requiring temperatures above 2200°F would need a different oven, but these represent a small fraction of bladesmithing applications.
How does the side-opening door improve safety during quenching?When you open the door to remove a blade at critical austenitizing temperature (often 1450-1950°F), everything is extremely hot including the door itself. The 180-degree side-swing design moves that super-heated door completely out of your way and away from your body, giving you clear access to the chamber and an unobstructed path to your quench tank. This is vastly safer than a drop-down door that stays in your workspace.
Is this a made-to-order item or do you stock it?This oven can be ordered either way. The special pricing on this page is for made-to-order units shipped directly from Evenheat's Michigan factory, which involves a lead time. If you need it faster, contact us—we often have LB Series ovens in stock at our Atlanta location that can ship immediately. We'll help you choose the best option for your timeline.
Does buying from Peach State Pottery affect my warranty?No. We are an authorized Evenheat dealer. Your two-year warranty is fully valid and you have direct access to Evenheat’s support team. Buying from an unauthorized seller can void your warranty entirely.
