A Jen-Ken kiln suits a home potter who fires cone 04 bisque and cone 5 to 6 glazes and likes buying from the people who build the kiln. Jen-Ken has made electric kilns in Lakeland, Florida since 1951, from a 120V pottery kiln up to 9 cubic foot studio models. Every pottery model on its site tops out at 2,300°F (1,260°C), so it is a mid-fire brand, not a cone 10 brand.
This review is research-based. We compared Jen-Ken's product pages, warranty page, FAQ and owner's manual with dealer pages, checked October 2026. We did not fire these kilns, and where Jen-Ken's pages contradict themselves we print both figures.
Verdict: is a Jen-Ken kiln a good buy?
Yes, for the right potter. Jen-Ken publishes the full electrical line for every model, ships an Orton AutoFire controller as standard, and covers brick kilns, elements and thermocouples for 2 years.
The limits are just as clear. No Jen-Ken pottery kiln is rated past 2,300°F, a few spec tables contain errors you must clear up by phone, and in October 2026 every pottery listing on the shop showed "Sold out". Call for a lead time before you plan a studio around one.
Jen-Ken pottery kiln specs side by side
All figures below come from Jen-Ken's own product pages. Interior is listed by Jen-Ken as width by depth; weights are kiln weight, then average shipping weight.
| Model | Power | Breaker, wire, receptacle | Max temp and cone | Interior and cu ft | Brick and weight |
|---|---|---|---|---|---|
| 11/9, 15A | 120V, 15A, 1,800 W | 20A, 12 gauge, 5-15P | 2,100°F; cone 04 to 06 use | 11 x 9 in, 0.55 cu ft | Brick not published; 50 lb (70 lb shipped) |
| 11/9, 17A | 120V, 17A, 1,800 W | 20A, 12 gauge, 5-20P | 2,250°F; up to cone 6 | 11 x 9 in, 0.55 cu ft | Brick not published; 50 lb (70 lb shipped) |
| 15/9 | 240V, 15A, 3,600 W | 20A, 12 gauge, 6-20P | 2,300°F; cone not listed | 15 x 9 in, 0.99 cu ft | 2,300°F firebrick; 70 lb (120 lb) |
| The Emerge 15/13 | 240V, 22A, 5,280 W | 30A, 10 gauge, 6-30R | 2,300°F; cone 8 or 9 (see note) | 15 x 13 in, 1.4 cu ft | 2,300°F firebrick; 100 lb (160 lb) |
| 1815 | 240V, 20A, 4,800 W | 30A, 10 gauge, 6-30R | 2,300°F; up to cone 8 | 18 x 15 in, 1.8 cu ft | Brick not published; 100 lb (125 lb) |
| 1822 | 240V, 26A, 6,240 W | 30A, 8 gauge, 6-30R | 2,300°F; up to cone 6 in the text | 18 x 22 in, 3.24 cu ft | Standard brick not published; 150 lb (205 lb) |
| Mega Coil 1822 3" | 240V, 30A, 7,200 W | 60A, 6 gauge, 6-50R | 2,300°F; cone not listed | 18 x 22 in, 3.24 cu ft | 3 in; 175 lb (250 lb) |
| 2422 | 240V, 36A (42A in text), 8,640 W | 40A, 8 gauge, 6-50R | 2,300°F; cone 6 to 8 | 24 x 22 in, 5.75 cu ft | Standard brick not published; 200 lb (240 lb) |
| 2422 3" High Fire | 240V, 42A, 10,080 W | 50A, 6 gauge, 6-50R | 2,300°F; cone 8 | 24 x 22 in, 5.75 cu ft | 3 in; 200 lb (260 lb) |
| JK² 22 | 240V, 45A, 10,800 W | 40A, 8 gauge, 6-50R | 2,100°F in table, 2,300°F in text; low-fire | 27 x 27 x 22 in, 9 cu ft | Brick not published; 225 lb (435 lb) |
Source conflicts on Jen-Ken's own pages, checked October 2026: the 2422 lists 36A in its spec table and a "42-amp draw" in its description. The JK² 22 lists a 45A draw on a 40A breaker, and 2,100°F in one place and 2,300°F in another. The 1822 pairs a 26A draw with a 30A breaker, while Skutt pairs its 26.7A KM-818 with a 40A breaker. The Emerge is "designed to fire up to cone 8" in one section and "reaches up to cone 9" in another. Treat the kiln's nameplate and a call to Jen-Ken as the final word.
These are the maker's stated figures. Have a licensed electrician check or install the circuit, size the breaker and wire from the nameplate on the kiln you receive and from local code, and fit the receptacle before delivery. Jen-Ken's manual says never to use an extension cord, and its FAQ says you may need an electrician to bring 240V to your studio. Do not wire a kiln circuit yourself.
How Jen-Ken names its kilns
The numbers match the interior size Jen-Ken lists: an 11/9 is 11 x 9 inches, a 1822 is 18 x 22 inches, a 2422 is 24 x 22 inches. A "3 inch" or "-3" in the name means 3 inch brick, which Jen-Ken says gives about 20% more insulation than its standard brick. Jen-Ken does not publish the standard brick thickness, so ask.
AF3C refers to the standard Orton AutoFire 3-button controller. Mega Coil models have oversized, heavy-gauge elements that Jen-Ken says last longer. Ceram-a-Glass models are dual-media kilns for pottery and glass, and JK² is a large low-fire line.
Jen-Ken 11/9: the 120V pottery model
The 11/9 is the only kiln in Jen-Ken's 120V collection labeled for ceramics; the other 120V models are glass kilns, an annealer and a knife kiln. It comes in two versions. The 15A version plugs into a NEMA 5-15 receptacle and reaches 2,100°F, which Jen-Ken pitches for cone 04 to 06 work. The 17A version needs a NEMA 5-20 receptacle on a dedicated 20A circuit and reaches 2,250°F, enough for cone 6 glazes by Jen-Ken's description.
At 0.55 cubic feet it holds a few mugs or test tiles. Jen-Ken lists a 20A breaker and 12-gauge wire for both versions.
- Power: 120V; 15A or 17A; 1,800 W
- Breaker, wire, receptacle: 20A, 12 gauge; 5-15P (15A) or 5-20P (17A)
- Max temperature: 2,100°F (15A) or 2,250°F (17A)
- Interior: 11 x 9 in, 0.55 cu ft
- Brick: not published by the maker
- Controller: Orton AutoFire AF3C 3-button
- Weight: 50 lb kiln, 70 lb average shipping (UPS)
- Price band: typically $1,550 to $1,700 at Jen-Ken's store in October 2026, plus shipping; check the live price
Pros
- Runs on 120V
- Cone 6 on the 17A version
- Ships by UPS rather than freight
Cons
- Small chamber
- 15A version is low-fire only
- Brick thickness not published
Who should skip it: Wheel throwers who want a full shelf of mugs per firing, and anyone without a dedicated 20A circuit for the cone 6 version.
The Emerge 15/13: 240V on a 30A circuit
Jen-Ken aims The Emerge at home studios, classrooms and beginners who want room to grow. It draws 22A at 240V, uses a 30A breaker, 10-gauge wire and a 6-30R receptacle (the same family many dryers use), and holds 1.4 cubic feet. Large handles and a two-position lid prop are listed features.
Confirm the cone rating: one section says cone 8, another cone 9, though the 2,300°F maximum is consistent. Either leaves headroom for cone 5 to 6.
- Power: 240V, 22A, 5,280 W
- Breaker, wire, receptacle: 30A, 10 gauge, 6-30R
- Max temperature: 2,300°F (1,260°C); cone 8 or 9 per the page
- Interior: 15 x 13 in, 1.4 cu ft
- Brick: firebrick rated to 2,300°F; thickness not published
- Controller: Orton AutoFire AF3C 3-button
- Weight: 100 lb kiln, 160 lb average shipping (motor freight)
- Price band: typically $1,900 to $2,050 at Jen-Ken's store in October 2026, plus freight
Pros
- Modest 30A circuit
- Light for a 240V kiln
- Aimed at beginners
Cons
- Conflicting cone figures on the page
- Freight shipping
- Smaller than an 18 inch kiln
Who should skip it: Potters who already fill a kiln every week; the 1822 holds more than twice as much.
Jen-Ken 1822 and Mega Coil 1822 3": the home studio size
The 1822 is Jen-Ken's answer to the 18 inch kilns most home potters shop. Its 22 inch depth gives 3.24 cubic feet, more than a Skutt KM-818's 2.6. Jen-Ken lists 26A and 6,240 W at 240V on a 30A breaker, 8-gauge wire and a 6-30R receptacle. As noted above, that breaker is small for the draw compared with how other makers size theirs, so ask Jen-Ken and your electrician to confirm it from the nameplate.
The Mega Coil 1822 3" is the same chamber with 3 inch brick, heavier elements, solid-state relays and the 12-key AutoFire. Jen-Ken lists 30A and 7,200 W on a 60A breaker with 6-gauge wire and a 6-50R receptacle, a much bigger circuit for the same chamber.
- 1822 power: 240V, 26A, 6,240 W; 30A breaker, 8 gauge, 6-30R
- Mega Coil 1822 3" power: 240V, 30A, 7,200 W; 60A breaker, 6 gauge, 6-50R
- Max temperature: 2,300°F (1,260°C) for both
- Interior: 18 x 22 in, 3.24 cu ft
- Brick: standard thickness not published (1822); 3 in (Mega Coil)
- Controller: AutoFire AF3C 3-button (1822); AutoFire 12-key (Mega Coil)
- Weight: 150 lb and 175 lb kiln; 205 lb and 250 lb average shipping
- Price band: typically $2,600 to $2,750 (1822) and $3,400 to $3,550 (Mega Coil) at Jen-Ken's store in October 2026, plus freight
Pros
- Deeper chamber than most 18 inch kilns
- 3 inch brick and heavier elements on the Mega Coil
- Full electrical data published
Cons
- Cone 8 ceiling
- Standard model's breaker figure needs confirming
- Mega Coil needs a 60A circuit
Who should skip it: Anyone who wants to fire cone 10 porcelain or stoneware; a Skutt KM-818 is rated to cone 10 on a 40A circuit.
Jen-Ken 2422 3" High Fire: the big-load option
The 2422 3" High Fire suits classes, potters who sell, or anyone firing wide platters. Jen-Ken lists 42A and 10,080 W at 240V on a 50A breaker with 6-gauge wire and a 6-50R receptacle, 3 inch brick walls and lid, lid lifters and 5.75 cubic feet. It takes a 21 inch full shelf or two half shelves, and square pieces up to 15 x 15 inches.
"High Fire" here still means 2,300°F, which Jen-Ken calls cone 8. The standard 2422 (36A or 42A depending on which line of its page you read, 40A breaker) is cheaper but does not list 3 inch brick.
- Power: 240V, 42A, 10,080 W
- Breaker, wire, receptacle: 50A, 6 gauge, 6-50R
- Max temperature: 2,300°F (1,260°C), cone 8
- Interior: 24 x 22 in, 5.75 cu ft
- Brick: 3 in walls and lid
- Controller: AutoFire AF3C 3-button with 25 user programs; 12-key, Slide or TAP II upgrades
- Weight: 200 lb kiln, 260 lb average shipping
- Price band: typically $4,000 to $4,350 at Jen-Ken's store in October 2026, depending on controller, plus freight
Pros
- Large 24 inch chamber
- 3 inch brick
- Lid lifters included
Cons
- 50A circuit
- Still capped at cone 8
- Heavy freight delivery
Who should skip it: Hobby potters firing a few pieces a month; it will sit half empty.
Controllers on Jen-Ken kilns
Most Jen-Ken pottery kilns ship with the Orton AutoFire AF3C 3-button controller, which stores 25 user programs plus slow, standard and fast cone-fire schedules. Listed upgrades are the AutoFire 12-button (AF4000, the only one with multi-thermocouple zone control), the AutoFire Slide touchscreen and the SDS TAP II touchscreen. Our kiln controller guide explains cone-fire and ramp-hold modes.
What Jen-Ken does well
Jen-Ken prints the six figures an electrician needs on every product page: volts, amps, watts, breaker, wire gauge and receptacle, plus kiln weight and shipping weight. The range is wide, from a 120V cone 6 option to several 240V kilns on a 30A circuit, deep 22 inch chambers and dual-media Ceram-a-Glass models. Buying direct means agreeing voltage, controller and brick with the factory before the kiln is built, and Jen-Ken advertises lifetime phone support.
Weak points
The cone 8 ceiling is the main one: a Jen-Ken pottery kiln cannot fire clay or glaze labeled cone 10, and even for cone 6 it has less headroom as elements age than a kiln rated to 2,350°F. Several product pages contradict themselves, standard brick thickness is not published, most models ship by motor freight, and dealer coverage is thinner than Skutt's, so parts usually come from Lakeland.
Where Jen-Ken kilns are made and how they are sold
Jen-Ken builds its kilns at its shop in Lakeland, Florida, under the parent company Sir-Ramic Porcelain, Inc. Most are sold through Jen-Ken's own web store, where you choose controller and relay upgrades, and dealers such as Soul Ceramics list some models. Jen-Ken's FAQ puts prices at roughly $1,200 to $11,400 across the whole range, before shipping. It also sells scratch-and-dent kilns in a "Garage Sale"; our kiln for sale guide covers what to check on any used or refurbished kiln.
Warranty and support
Jen-Ken's warranty page gives 2 years on brick kilns, 1 year on fiber kilns, and 2 years on elements, thermocouples and mechanical relays. Controllers are warranted by their makers: 2 years for Orton AutoFire and 3 years for SDS TAP.
Exclusions include improper electrical installation, firing on or near combustible surfaces such as wood floors, reduction, lusters and salt, hot spaces such as desert garages, and problems not reported within 15 days. Labor is covered only for work done at the factory.
Setting up a Jen-Ken kiln at home
Jen-Ken's owner's manual asks for at least 12 inches from any surface, and its diagram shows 18 inches from anything but a block wall, so use 18 inches. It wants a cement floor or fireproof base under the stand, a dry, covered room vented outside, no closets, and no outdoor firing. Keep glaze and kiln wash off the elements and vacuum the grooves. For venting options, see our kiln vent guide.
Kilns get hot on the outside and give off fumes during firing. Keep children and pets away, follow the clearances in Jen-Ken's manual, and vent the room. Clay and glaze dust contains silica: clean it wet, never by dry sweeping, and wear a NIOSH-approved respirator when mixing dry materials. Follow the maker's manual or a qualified kiln technician for element and relay work.
Who should buy a Jen-Ken kiln, and who should skip
Buy a Jen-Ken if you fire cone 04 bisque and cone 5 to 6 glazes, want a US-made kiln from a family company, and like ordering exactly the controller and brick you want from the factory. The Emerge and 1815 suit 30A circuits, and the 1822 gives a deeper chamber than most 18 inch kilns.
Skip Jen-Ken if you want cone 10, want a kiln you can pick up from a local dealer next week, or want hard element holders, which are an L&L feature.
