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.

Will it work in my space? Power check

Bench-top kiln, no stand. Not included: furniture kit (two 7¼″ × 7¼″ shelves, brush, shelf primer), sold separately. Plugs into a standard 120V 15A outlet (12A, 1440W).

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
What's the advantage of dual access on such a small kiln?Front access lets you build pieces directly on the shelf and slide them in horizontally—perfect for delicate arrangements and techniques like raking or roll-ups. Top access makes it easy to lower slumping molds or draping forms into place without disturbing shelf placement. On a small kiln where precision matters, having both options prevents costly mistakes and gives you flexibility for different techniques.
Can this kiln handle a full annealing cycle for glass?Yes. The hybrid fiber-and-firebrick construction is specifically designed for glass work. Fiber provides fast heat-up, while the firebrick delivers the thermal mass needed for controlled, even cooling during extended annealing holds. The lid vent also helps you manage cooling rates precisely.
Will this run on a standard household outlet?Yes. The Studio Pro STP operates on 120V at 12 amps and has a standard NEMA 5-15 plug, so it plugs into a standard 15-amp household outlet. No special wiring or electrician required. Just make sure the circuit isn't shared with other high-draw appliances during firing.
What size projects can I realistically fit in an 8" × 8" chamber?This kiln is ideal for jewelry components, test tiles, small fused pendants, ornaments, and design elements that will be incorporated into larger pieces. You can fit a single 6" square piece comfortably, or stack shelves to fire multiple smaller items like earrings or cabochons. It's not meant for dinner plates, but it's perfect for samplers and production jewelry work.
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.
