Dynatrol controller. Cracked lid, but has never affected firing (new ones available on line). Kiln as it stands is 8 cu ft. but I have an extra ring to make it 10 cu ft. New elements have 3 firings on them to cone 6. Electronic programs work great! New thermocouples and relays. It's on wheels, and has a pulley system to keep the lid open. Home made kiln vent included. Some furniture included. Pick up only. Cash only.
