Olympic Kilns · Electric Kiln · Medallion Artist Series Olympic Medallion Artist Series 2823HE Electric Kiln MAS2823HE · 208/240V, 1-Phase or 3-Phase · 28.25″ W × 22.5″ D · 8.34 cu ft · Cone 10 / 2350°F The MAS2823HE is the large-capacity flagship of Olympic's Medallion Artist Series, giving production studios and teaching programs a wide, deep firing chamber without stepping up to a full front-loading kiln. With 8.34 cubic feet of Cone 10 capacity and a 3-inch brick wall, it's built to run heavy stacking loads day after day. It's available wired for either 1-phase or 3-phase power, so it fits a wider range of studio and commercial electrical services.

Key features
KilnStar Digital Controller Pre-programmed with Cone Fire and Ramp/Hold modes. Features delay start, alarm, and thermocouple offset adjustment.
3-Inch Brick Insulation High-efficiency firebrick construction reduces energy consumption and improves firing performance to Cone 10.
Large-Capacity Firing Chamber 28.25″ wide by 22.5″ deep chamber holds significantly more ware per firing than standard MAS sizes.
Stainless Steel Jacket Durable outer shell with corrosion resistance. Provides structural support and a clean, professional appearance.
Balanced Element Design Kanthal A-1 heating elements arranged across the wide chamber for even heat distribution during Cone 10 firings.
Metal Stand Heavy-duty steel stand rated for the added weight of this large-capacity model. Casters are an optional add-on.
Pilot Light External indicator shows when kiln is receiving power and heating elements are energized.
Type K Thermocouple Industrial-grade temperature sensor positioned for accurate chamber temperature reading.
Optional accessories
Solid State Relay (SSR) Upgrade Replaces mechanical contactors for silent operation and extended element life. Especially valuable on heavy-use production kilns.
Kiln Furniture Kit Shelves, posts, and stilts sized for this 28.25″ chamber. Essential for stacking large production loads efficiently.
Orton Kiln Vent System Downdraft venting system removes fumes and moisture during firing. Improves studio air quality and glaze results.
Automatic Lid Lift Spring-assisted lid opener reduces physical strain when loading this large, heavy lid.
Heavy-Duty Rolling Stand Upgraded steel stand with larger locking casters rated for this kiln's added weight and footprint.
Power Interrupt Safety System Automatically shuts down kiln if lid is opened during firing. Adds safety protection in multi-user studio environments.
Multi-Zone Control Upgrade Independent control of top, middle, and bottom element sections. Compensates for natural heat rise across this large chamber.
3-Phase Wiring Configuration Reduces amperage draw compared to 1-phase for facilities with 3-phase service already in place.
Emergency Parts Kit Spare thermocouple, element connectors, and relay components. Minimizes downtime if a component failure occurs.
Type S Thermocouple Upgrade Platinum-based sensor for improved accuracy and longevity at high temperatures. Recommended for frequent Cone 8-10 firings.

  • 4.3-inch full-color touchscreen with graphical temperature display
  • Unlimited program storage with cloud backup capability via USB
  • Up to 32 segments per program for complex firing schedules
  • Real-time graphing shows temperature curve during firing

Common questions
Do I need an electrician to install this kiln?
Yes. The MAS2823HE is direct-wired and requires a dedicated circuit sized to your chosen configuration — up to 70 amps for 1-phase 208V service, or as low as 50 amps on 3-phase service. A licensed electrician must determine the correct breaker, wire gauge, and connection method for your building's available power, and installation must meet local electrical codes. Installation by anyone other than a qualified electrician may void your warranty.
Should I choose 1-phase or 3-phase wiring?
Most home and small studio buildings only have 1-phase power available, so that's the standard configuration. If your building already has 3-phase service — common in commercial and school buildings — the 3-phase option draws significantly less amperage (as low as 32-36A vs. 48-55A on 1-phase) and can be the more efficient choice. Confirm what's available at your location with your electrician before ordering.
Does this kiln come with shelves and posts?
No. Kiln furniture is sold separately because different users have different needs based on the work they're firing. For a chamber this size, we recommend a furniture kit with at least 4-6 full shelves and a full assortment of posts and stilts to make the most of the 8.34 cubic foot capacity. Contact Peach State Pottery for a recommendation sized to your typical loads.
Is this kiln suitable for a shared studio or teaching program?
Yes, the MAS2823HE's large capacity makes it a popular choice for community studios, universities, and production potters who need to fire many pieces at once rather than running frequent small loads. We recommend pairing it with the Genesis touchscreen controller and Power Interrupt Safety System in any multi-user environment.
How do I register my warranty?
Register your kiln at the Olympic Kilns website within 30 days of delivery. You'll need your serial number (located on the control panel label), purchase date, and proof of purchase from an authorized dealer. Warranty registration is required for coverage and must be completed within the 30-day window. Peach State Pottery can assist with registration if needed.
