Common questions
What types of steel can I heat treat in the KM24 Double Barrel?
The KM24 reaches 2350°F, which is sufficient for heat treating high-carbon steels (1095, 1084, W2), stainless steels (440C, AEB-L, 154CM), tool steels (O1, A2, D2), and Damascus steel. This temperature range covers the austenitizing temperatures for virtually all common knife-making alloys. For specialty stainless steels requiring atmosphere control, consider adding the optional gas inlet kit to prevent oxidation during heat treating.
Do I need the gas inlet for atmosphere control?
The gas inlet is optional and depends on your steel types and desired finish. For most high-carbon steels, air atmosphere is sufficient since you'll grind away scale during finishing. For stainless steels or when you want to minimize decarburization and surface oxidation, the gas inlet allows you to introduce argon or nitrogen for a protective atmosphere. Many professional knife makers start without it and add it later as their production demands increase.
What controller comes standard with this oven?
The KM24 includes a Sentinel Touch Xpress touchscreen controller with ramp and hold capabilities, allowing you to set target temperatures and soak times for proper heat treating cycles. You can upgrade to the Genesis touchscreen controller for more advanced programming features including 8-segment profiles, temperature graphing, and the ability to store multiple custom programs for different steel types.
How does the Double Barrel KM24 compare to single-chamber knife ovens?
The Double Barrel has the same 24-inch depth as the standard KM24 but a wider, taller chamber, so you can load more blades per cycle or fit wider pieces. It is one chamber with one controller, so everything in a load runs the same program. For small batch or hobby knife makers, the standard KM24 may be sufficient, but production bladesmiths benefit significantly from the extra capacity.
Is Peach State Pottery an authorized Paragon dealer for warranty coverage?
Yes, Peach State Pottery is an authorized Paragon dealer. Your one-year limited warranty from Paragon Industries is valid when purchased through us, but you must register your oven within 30 days of delivery. Warranty coverage is only valid through authorized dealers—purchasing from unauthorized resellers voids your warranty. We also provide ongoing technical support and can supply genuine Paragon replacement parts throughout the life of your oven.

Common questions about this kiln

Still stuck? Call or text (470) 264-3563 and talk it through with a real person.

Is freight delivery included in the price?

No. Kiln prices do not include freight, and we do not quietly build it into the product price. Freight is charged at a flat rate based on your delivery address and is shown at checkout. Liftgate service is included when it is needed, and standard delivery is curbside. You can estimate your delivered cost with the ZIP code tool above the Add to Cart button.

Can I return this kiln if it is not right?

Return requests can be submitted within 30 days of delivery. The kiln needs to be in its original packaging, in new and resellable condition, and approved before it is sent back. A restocking fee may apply. Completing the manufacturer's recommended first test firing does not by itself make a kiln non-returnable, so you can confirm it works before you commit. Full terms are on our Returns page.

What electrical supply do I need for this kiln?

The Specifications tab on this page lists this model's voltage, amperage, required breaker size and NEMA plug configuration. Most 240V kilns need their own dedicated circuit fitted by a licensed electrician, while many 120V models run from a standard household outlet. If you are unsure what your space can support, call or text (470) 264-3563 before ordering.

Does this kiln come with a warranty?

Yes. This kiln carries the Paragon manufacturer warranty. Coverage length, what is included and any registration deadline are listed in the Specifications tab on this page. We are an authorized Paragon dealer, which is a condition of warranty coverage on most kiln brands.

What comes with the kiln, and what do I need to buy separately?

The What's Included tab on this page lists exactly what ships with this kiln. Most kilns need shelves, posts and kiln wash before your first firing, and these are not always included. A vent is recommended for indoor installations. Any add-ons available for this model are shown above the Add to Cart button.
