Ideal for artists working in pottery, glass, or jewelry, this 120-volt powerhouse is compact enough for any studio yet robust enough to produce professional-quality results.

Simplified Control for Complex Creations

Every HotBox E model comes standard with the intuitive Genesis Spark controller.

It features industry-specific presets and offers 30 customizable programs. With Wi-Fi connectivity, the controller supports seamless software updates, built-in diagnostics, maintenance tracking, and automatic PID adjustments.

Customizable to Fit Your Artistic Needs

The HotBox E adapts to your creative demands. Choose to expand its capabilities with an optional collar, either bead or blank, to reach firing temperatures of up to 2000°F and add an extra 4.5 inches of depth. For glass artists, the bead collar is a game-changer, offering a specialized door for the annealing process, ensuring your creations cool at the perfect rate to preserve their beauty and integrity.

Essential Accessories for Your Firing Success

The comprehensive Furniture Kit for the HotBox E is designed to maximize your kiln's space. It includes two layers of 5.5" x 5.5" shelving for efficient stacking of your ware, assorted small square posts to support your projects at varying heights, and a one-pound bag of kiln wash to keep your kiln clean and ready for action. This kit is an essential addition for serious artists.

Advanced Upgrades for Enhanced Operations

For those seeking even greater control over their firing conditions, the Solid State Relay upgrade is an excellent investment. This feature, suitable for up to 20 amps with 1 phase wiring, ensures smoother power control to your elements, leading to more consistent temperatures and extended element life.

Choose the voltage that matches the electrical service where the kiln will be installed. Some kilns are available in only one voltage, while others can be ordered in multiple voltages. If both 120V and 240V are available, 240V is generally the preferred choice because it places less demand on your electrical system, while 120V offers the convenience of operating on a dedicated standard household circuit. If both 208V and 240V are available, select the voltage that matches your building's electrical service—240V is most common in homes, while 208V is common in many commercial, educational, and institutional buildings. If you're unsure which voltage you have, confirm it with your electrician before ordering.

Your kiln must be built to match the electrical service where it will be installed. Choose single-phase if that's what your building has (almost all homes do). Choose three-phase only if your building has three-phase power available. If both are available, three-phase is generally the preferred option. If you're unsure, verify the available electrical service with your electrician before placing your order.

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.)
