Common questions
What's the difference between fusing and slumping, and can this kiln do both?
Yes, the HS-12G handles both processes. Fusing joins multiple pieces of glass together at temperatures between 1300°F–1500°F to create flat panels or decorative elements. Slumping (also called draping) reshapes fused glass over or into molds at lower temperatures around 1200°F–1350°F to create bowls, plates, and curved forms. The HS-12G's 1700°F maximum temperature provides plenty of range for full fusing, tack fusing, and slumping, plus controlled annealing to properly cool your glass work.
Do I need an electrician to install this kiln?
No electrician needed for the HS-12G. It operates on standard 120V household power and plugs into a regular 15-amp outlet with a standard three-prong plug. You should use a dedicated 15-amp circuit (meaning no other appliances sharing that breaker) to ensure reliable operation. Avoid using extension cords. This makes the HS-12G one of the most convenient glass kilns for home studios, classrooms, or spaces without 240V wiring.
What size glass projects can I fire in the HS-12G?
The 12″ × 12″ floor provides 144 square inches of working space, ideal for jewelry components, small plates up to 10″ diameter, decorative tiles, suncatchers, and cabinet glass panels. The 6″ height accommodates stacking multiple layers for casting projects or tall slumping molds. This capacity suits beginning glass artists, jewelry makers, and hobbyists working on smaller production runs or one-of-a-kind pieces. For larger platters or architectural panels, you would need to step up to the HS-18G or HS-24G models.
What does the solid state relay controller do?
The solid state relay (SSR) provides more precise temperature control compared to basic infinite switches found on entry-level kilns. The SSR rapidly pulses power to the heating elements to maintain steady temperatures critical for proper glass annealing and preventing thermal shock. This precision matters most during the annealing hold and controlled cooling phases where temperature consistency prevents cracking. The digital controller displays the current temperature and allows you to set target temperatures for each stage of your firing.
Is my warranty valid if I buy from an online retailer?
Hot Shot honors warranties only when purchased through authorized dealers like Peach State Pottery. Buying from unauthorized resellers, auction sites, or third-party marketplaces may void your warranty coverage. The one-year limited warranty must be registered within 30 days of delivery and covers manufacturing defects in materials and workmanship. Peach State Pottery provides direct support for warranty claims, technical questions, and replacement parts throughout your kiln's lifetime.

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 HotShot Oven & Kiln manufacturer warranty. Coverage length, what is included and any registration deadline are listed in the Specifications tab on this page. We are an authorized HotShot Oven & Kiln 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.
