The Orton downdraft vent pulls fumes out of the kiln, allowing air to enter.
Electric kilns are naturally hotter at the top.
With KilnVent, hot gases near the top of the kiln are drawn down. Clay bodies, glazes, decals, lusters need air to fire. Many problems with color, glaze fit and porcelain mildew occur because of too little oxygen in the kiln. Clay products contain carbon and organics. These react with oxygen in the air to form carbon monoxide in the firing.
