32 Cu/ft Caternary Arch hybrid kiln with drop down ash pit, brick grate, NG 400K BTU x2 power burners, center hinge pin swing door, and rolling stoke hole doors. We used 18"x18"x2.5" 55% alumina for the floor, Clipper Super Duty High Alumina #1 arch, Clipper Super Duty High Alumina walls, Seneca 60P grate and flue, BNZ 2660 for the door, and BNZ 2300 for cold face insulation/sub floor to build this kiln. The arch is 4.5” hard brick, 3” BNZ 2300, 2 layers 6# 1” fiber, chicken wire mesh, 1” of 80 lb scratch coat sanded with fiber stucco/3 gallon vermiculite custom mix for skin coat. We installed 2x 400k btu/hr burners to bring the kiln to cone 10 in 12 hrs firing time. Interior dimensions hold 3 stacks, 12x24 shelf stacks. 1/4” mild steel framing ranging from 3” to 5” give this kiln and swing door structural integrity. Rolling stoke hole doors make burning wood easy, and this kiln can burn about 3/4 cord of split hardwood in 14 hrs from 1600-2300 degrees with a 10 hour hold at temp to build ash. Many thanks to Betsy Alwin, Joanne Seongweon Lee, and Anderson Ranch Art Center for the opportunity, and hospitality during our 2 week stay. Robert Williams and I built the kiln in 12 days, and we fired the kiln successfully in 24 hours to Cone 10, burning about 3/4 cords of wood.
