Hot Shot Oven & Kiln HS-7GW Wax Burnout Kiln

The 7G Wax Burnout Kiln is designed specifically for lost wax casting, metal clay firing, enameling, and other precision studio applications. Its compact footprint and reliable temperature control make it an ideal solution for jewelers, knife makers, and artists who need consistent, repeatable results in a small studio-friendly kiln.

Built-In Burnout Venting

Designed for lost wax casting, this kiln includes a 0.75-inch vent hole with plug that allows proper ventilation during the burnout process. This feature helps wax exit molds cleanly, reducing defects and preparing molds for high-quality metal castings.

Versatile Applications for Artists and Jewelers

• Lost Wax Casting: Burn out wax cleanly to prepare molds for intricate metal designs.

• Metal Clay Firing: Achieve precise temperature control for strong, finished pieces.

• Enameling: Fuse powdered glass onto metal with consistent heat for durable finishes.

• Fused Glass Jewelry: Fire small glass components and jewelry pieces with precise temperature control.

Controller Options

The 7G Wax Burnout Kiln comes standard with the TAP&Go Single Setpoint Controller, a simplified controller designed for applications that don’t require complex firing programs. Simply enter your desired temperature and the kiln will automatically heat to that setpoint.

For artists who prefer expanded control and programming flexibility, two optional controller upgrades are available:

• SPARK Controller Upgrade – A modern full-color touchscreen interface that makes programming and monitoring firings simple.

• TAP Controller Upgrade – A larger touchscreen controller with advanced programming features, scheduling options, and enhanced usability.

Built for Reliable Studio Performance

From professional jewelers to multi-disciplinary artists, the 7G Wax Burnout Kiln offers dependable performance in a compact, easy-to-use design that fits comfortably in most studios.

Includes a 3-year manufacturer warranty.

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.)
