Customizable to Fit Your Artistic Ambitions

The 2831HE can be customized to match your specific needs, with options for 1-phase or 3-phase wiring and the ability to operate on either 208 or 240 volts. This flexibility ensures that the kiln can seamlessly integrate into your studio’s electrical setup. For higher voltage configurations or specific power requirements, Pottery Pulse is ready to assist with tailored options.

Versatility for a Spectrum of Artistic Mediums

Primarily designed for pottery and ceramics, the 2831HE can also handle glasswork with the addition of an optional dual-media lid element. This adaptability allows artists to expand their creative horizons, working across multiple mediums with ease.

For enhanced performance, Solid State Relays are recommended, offering quieter, more precise control while extending the life of the kiln. These relays are ideal for artists looking for greater accuracy and smoother operation in their firing processes.

Higher voltage means lower amperage draw and greater efficiency, which can save money long term. 240V and 208V cost the same—most home studios use 240V, while 208V is common in schools or large facilities. Amperage refers to the amount of electrical current a kiln draws—higher amps require heavier wiring and breakers.

Single-phase is what almost all homes have. If your facility has three-phase, you can choose either—but three-phase is typically the better long-term option due to smoother power and improved efficiency.

Mechanical relays are standard and reliable. Solid-state relays (SSR) offer silent operation, faster cycling, greater precision, and longer lifespan—ideal for frequent or high-accuracy firings.

The following controllers are used across kilns sold by Pottery Pulse. Not all models offer every option—available controllers are listed on each product page. Some kilns include only the standard controller, while most allow upgrades for added precision and convenience.

Not all kilns can use a collar, but Olympic’s Hot Box kilns can be ordered with a collar to expand versatility. A blank collar simply adds height to the firing chamber, while a bead collar adds the same height and includes a built-in bead or annealing door for quick-access lampwork projects.

This safety feature automatically cuts power to the heating elements whenever the kiln lid or door is opened. It prevents accidental burns, protects elements, and resumes power only when safely closed. (Also called an automatic lid shutoff on Olympic kilns.)
