OUTSIDE DIMENSIONS: 20-3/4" diameter, 27-1/2" tall (including the handle)
INSIDE DIMENSIONS: 19-1/2" diameter x 24" Tall*
*please note that you will lose about 5" of interior height to the shelf and shelf supports.
PLEASE NOTE: This kit DOES NOT INCLUDE: a propane tank, kiln posts, garbage cans, or metal tubs.
The kiln is shipped with a bag of shredded paper inside. Not only does it provide crush resistance during transit without adding excessive shipping weight, but it can also be used as reduction material for your first firing. Also great reduction material: leaves, sawdust, excelsior, hamster/gerbil bedding, and pine needles (links to excelsior and small pet bedding are provided so you can see what we're referring to). Your kiln was also probably packed with some styrofoam packing peanuts or other styrofoam-like items to protect it. Do NOT use these for reduction material. In most cases (when you aren't using commercially available liquid raku glazes), raku glazes should be mixed dry, then prepared with water as needed for each firing session. This is particularly important in glazes with a high content of gerstley borate. Safety is of utmost concern when raku firing. Make all participants and spectators aware of the open flame and the layout of the raku set-up so that no one gets hurt. Also make them aware of the flurry of activity that will occur when the firing is complete and the pots are moved to the reduction material or water. A “dry run” of this is helpful in choreographing duties and requirements of the participants as well as making sure that reduction material and water is in a convenient location. An extra bucket of water on hand for safety is also recommended. We encourage you to experiment with how regular low-fire glazes work in a raku firing. Some will work great and some won’t, and you can only find out by testing.
- The raku kiln itself
- a case of 25 soft insulating firebricks that are rated to 2600°F, commonly called K26 bricks
- 1 - 15-1/2” full round kiln shelf
- 1 - propane torch (or burner, depending on who is talking about it)
- 100,000 BTU torch that works best with smaller propane tanks, like you’d get for your BBQ grill
- that 20 pound size tank will usually last for 2-3 firing cycles
- or 500,000 BTU torch that works best with larger propane tanks
- the tank visible in the video is a 100 pound cylinder because when we have raku firings, we fire at least 5 or 6 times in a row for each tank
- I’d suggest using size torch with 40 pound or larger cylinders
- 1 pair of raku tongs, either the Kemper RK45 with teeth or the RK37 without teeth
- in my opinion, the RK45 are the more versatile tongs
- 1 pair leather welders gloves
- not appropriate for holding hot pots, but good for handling hot reduction chamber lids, etc.
