Building a firebox for your Heat Wave Raku Kiln

It's as simple as stacking up some bricks. You may use insulated firebrick OR hard firebrick. You can stack them in several different ways. Here is how we did it as seen in the diagram.

This design uses 37 standard 9"x4.5"x2.5" firebrick. If you were ambitious, you could cut the bricks in arcs to create a circular firebox that more closely matches the shape of the kiln. Note the diamond figure in front of the burner port represents one of the posts that are placed under the bottom kiln shelf. The post is placed at an angle so that it acts as a target brick, splitting and deflecting the flames to spread more evenly into the kiln.

*Note: Superwool Prime Ceramic Fiber Blanket comes with the following health hazard summary from the manufacturer:

“This amorphous wool was designed for enhanced solubility in lung tissue. Rats have been exposed 6 hours/day, 5 day/week during two years at an average concentration of 200 fibers/cc (200 to 300 times higher than the concentrations found in manufacturing plants).

Preliminary findings indicate:
• No formation of fibrous tissue
• No significantly elevated tumor incidence over the negative (air) control group
• Reversible cellular changes similar to the effects observed after inhalation of inert dust.”

**Note: Firebox bricks, burner, hose assembly and regulators are not included. Each sold separately.**
