The Mega Coil for Home Studios and Apartment Potters
If you've been wanting a serious cone 8 ceramic kiln but didn't think your home electrical could handle one, the Jen-Ken AF 1822 Mega Coil is built for you. It's the smallest and most accessible kiln in the Mega Coil family, pulling only 30 amps on 240V. That's less than a standard electric dryer. Most home studios, apartments, and garages can run this kiln without an electrical upgrade.
Lower amp draw doesn't mean compromise. You still get the Mega Coil technology that makes Jen-Ken Mega Coil kilns last 10 to 15 years longer than similarly sized kilns on the market. Oversized heavy gauge coils, one per full brick, with color coded wiring you can swap yourself in about 10 minutes if a coil ever fails. Same construction quality as the bigger Mega Coils, just sized for smaller studios.
Inside, you've got an 18" x 22" chamber with 3.24 cubic feet of capacity. Sized right for working at home, weekend potters, jewelry makers firing pieces in batches, and small studios. 3" firebrick walls hold heat efficiently, your firings stay on schedule, and the elements don't work harder than they need to.
Fires up to 2300°F (Cone 8), which covers earthenware, low and mid fire stoneware, glaze work, and bisque firings. Plugs into a standard NEMA 6-50 outlet with 6,240 watts.
Included with every order
A heavy duty stand sized for this kiln, the full operator manual, a 2 year limited warranty through Jen-Ken, and free freight shipping to the US Lower 48.
Who Is This Kiln For?
The AF 1822 Mega Coil is built for a specific kind of potter. Here's how to tell if that's you.
✓ Home studio potters with limited electrical
30 amps on 240V is way easier on a residential panel than the 36 to 55 amps the larger Mega Coils need. Often the difference between starting your home studio this month or waiting on an electrical upgrade.
✓ Weekend potters and serious hobbyists
If you fire a few times a month and care about doing it well, this gives you real cone 8 capability with the longevity benefits of Mega Coil construction, sized for actual home use.
✓ Jewelry makers and small batch ceramicists
3.24 cu ft is the right size for batches of pendants, small vessels, beads, ornaments, and jewelry components. Not too big, not too small.
✓ Potters upgrading from a hobbyist kiln
If you started with a 120V tabletop kiln and you're ready for real 240V cone 8 firing, this is the natural next step without committing to a full size production kiln.
The AF 1822 Mega Coil ships with the wall hanging digital Orton AutoFire 12 Key controller. This controller mounts on the wall away from kiln heat, keeping its components cool and extending its life. Loaded with cone fire schedules in slow, medium, and fast, plus 9 user programs, a 60 amp mercury relay, and the ability to track the cost of each firing. Upgrade at checkout to the AutoFire Slide touchscreen or the TAP Smart Controller with Wi Fi for phone or tablet control.
