All Kilns

Start from the material, not the price. Clay wants a deep chamber and a high ceiling, so look at ceramic kilns. Glass wants a wide, shallow chamber with elements in the lid so the heat falls evenly, which is glass kilns. Blades want a long narrow chamber sized by blade length, which is knife making ovens. Steel and tooling want tight temperature control, which is heat treating ovens.

A few kilns genuinely cross over, but most do one job well and the others badly. Firing glass in a tall ceramic kiln, for example, tends to give uneven results because the heat comes from the walls rather than above the piece.

Work backwards from your largest piece and your typical batch. Measure the tallest and widest thing you expect to fire, add a few inches of clearance, and check that against the interior chamber dimensions on the product page.

As a rough guide: under 1.5 cubic feet suits glaze tests, jewelry and small sculpture. Between roughly 2.5 and 4 cubic feet covers most working potters firing functional ware. Seven cubic feet and up is production, classroom and co-op territory. Our kiln finder does this calculation for you.

Some of the smaller ones, yes. The kilns in our beginner collection are chosen for exactly that, and the Paragon SC2 runs on standard 120V household power.

Be careful here, because not every kiln described as 120V is plug-and-play. Some 120V models still want a dedicated circuit with a locking plug. Always check the breaker and plug requirement on the product page rather than assuming, and browse the full 120V range if that is the constraint you are working with.

If the kiln holds much more than about 1.5 cubic feet, it almost certainly runs on 240V. Every studio and production kiln we sell does, and there are 181 of them in our 240V collection against 64 that run on 120V.

The practical question is whether your panel has spare capacity for a dedicated circuit of the right size. If it does not, adding one is an electrician's job and a real line in the budget, so price it before you choose the kiln.

Because a kiln pulls its rated amperage for hours at a time, electrical codes treat it as a continuous load and the circuit is sized above the draw. That is why a 26A kiln calls for a 40A breaker and a 56A kiln calls for a 70A one.

Check the breaker figure on the product page against your panel's spare capacity, and have a licensed electrician confirm the circuit before the kiln ships rather than after it arrives.

Match the cone rating to the clay body or material you fire, then leave headroom. Most earthenware fires around cone 04, mid-range stoneware around cone 5 to 6, and high-fire stoneware and porcelain at cone 9 to 10.

Buying a kiln rated exactly at your working cone means running it at maximum every firing, which shortens element life. A cone 10 kiln fired to cone 6 will outlast a cone 6 kiln fired to cone 6. Cone ratings vary within a product line, so check the individual model rather than the family.

All four are long-running American manufacturers and we are an authorized dealer for each, so the honest answer is that the job picks the brand. Olympic, an hour from us in Flowery Branch, Georgia, has the broadest range of ceramic, gas and glass kilns. Paragon has the deepest knife oven and glass fusing lines.

Evenheat is the one to look at if you want to choose your own controller, and Hot Shot builds compact knife, glass and heat treating ovens, several with a 120V option.

Most kilns are built to order, so the lead time comes from the factory rather than from us and varies by brand and model. If you have a fixed date, start with our quick-ship kilns, which are held for fast dispatch instead of being built to order.

If you need a specific model by a specific date, call (470) 264-3563 before ordering and we will check the current build time with the manufacturer.

By freight, not parcel. Shipping is discounted flat-rate freight calculated at checkout before you buy, based on the kiln's size and your delivery region, with no surprise charges afterwards.

That rate covers curbside delivery, residential delivery, appointment scheduling, tracking, and liftgate service where the delivery requires it. Standard rates apply across the contiguous United States. Alaska, Hawaii, US territories, Canada and international destinations are quoted individually. Full details are on our shipping page.

Performing the manufacturer's recommended initial test firing will not by itself void a return, as long as the other conditions in our policy are met. Most retailers treat any firing as final sale, so this is worth knowing before you buy.
