Hybrid 25 cu/ft Gas/Wood/Soda kiln built for full time potter in Niwot, CO. I added a drop down ash pit and super duty high alumina grate to this popular design I build often for private clients, schools, and art centers to aid in wood combustion. There are 2, 250k BTU Power Burners setup for 7” WC Natural Gas. Kiln is constructed using Super Duty High Alumina Kala hardbrick for longevity, 70% alumina mullite floor (no soda sticks to these brick), 70% alumina mullite door, IFB 2300 exterior insulation and subfloor, IFB 2300 cold face soft brick, 2 layers 6#, 1” fiber and vermiculite stucco over the arch. 3/16” mild steel framing makes this a lifetime kiln, with option to fire with gas, or wood, or both during the same firing. Kiln was completed in 10 days on location.
