Common questions
Why choose a vertical chamber over a horizontal Double Barrel oven?
A vertical chamber lets you suspend a blade from a rod hanger so it heats evenly along its full length without needing a long horizontal footprint in your shop — useful for longer blades or shops tight on bench space.
Can I still fire shorter blades horizontally?
Yes. The top hot zone includes a ceramic floor insert so shorter blades can be laid flat instead of hung, giving you both orientations in one oven.
What's the difference between the Vertical Base and a Vertical Pro?
The Base ships with dual solid-state relay control and independent zone thermocouples as standard. A SENTINEL Smart Fire or Touch Xpress controller upgrade is available if you want digital programmability instead of relay-based control.
Do I need the rod hanger system to use this oven?
No — it's an optional accessory. Without it, you can still use the top hot zone's ceramic floor insert to fire blades horizontally.
Is the warranty valid if I buy from Peach State Pottery?
Yes. Peach State Pottery is an authorized Paragon dealer, so your KM25 Vertical Base comes with Paragon's full one-year manufacturer's warranty. Register your oven within 30 days of delivery to activate coverage.

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.
