All Lightmaster kilns are CE marked and have captive key interlocks fitted to break full load before opening the kiln complying with both UK and European legislation.
Kanthal A1 spiral wound elements are used to heat the kiln. The elements are graded and located in grooves in the side walls and floor of the kiln giving uniform heat distribution throughout the chamber.
Potterycrafts Lightmaster kilns have dual contactors to provide protection against possible over-fires, when used in conjunction with Potterycrafts Kiln Controllers.
The kilns are constructed of a durable low thermal mass insulation brick with two high grade backup insulation boards this is all enclosed within a robust high quality pressed steel powder coated frame
Firing capacity: 250 litres (8.83ft³).
Maximum Temperature: 1300°C
Chamber dimensions:mm: 460 wide x 610 deep x 885 high
External dimensions:mm: 730 wide x 1090 deep x 1580 high
Power: 13.0 kW
Supply required: Single Phase-63 amps or 3 phase-20 amps per phase

Controller included: CERA-2(2-program memory each with 3 segments)
You can upgrade to CERA-5 , CERA-10or CERA-10+ for marginal extra cost.
Additional Safety Equipment available for kilns:
Kiln is made to order, delivery is approx 4-6 weeks (this will be confirmed when ordering)
CERAcontrol is the latest development in a long series of controllers, they incorporate new software giving improved efficiency and ease of programming together with up to date safety and diagnostic features.
CERA-5+ has 5 programs each with delay start, 5 heating/cooling ramps, soak, cut off and program pause.
This controller gives the benefit multiple heating and cooling ramps for pottery firing where usually two programs are used, having five ramps allows for several heating and/or cooling phases in the program.
CERA-10 has 10 programs each with 10 segments. Delay start and program pause. Each segment has a heating/cooling ramp, a target temperature and a soak. This controller is ideal for firings where a range of programs are frequently used.
It can be used for any firing requiring close control over multiple heating and cooling ramps such as macro crystalglazes and for glass slumping and fusing.
KM207 Zintec Hood for P5120 and P5121 Lightmaster Kilns and P59445 and P5945 Heatworker Kilns.
The ventilation hood is designed to remove the excess heat from the kiln area.
It is positioned directly above the kilnand so it removes the air directly from around the kiln, as well as fumes from the flue, keeping the kiln area cooler.
The hood has a 150mm diameter spigot on top for connection to customers’ exhaust ducting.
We recommend connecting the spigot directly to the room extraction system or to an exhaust fan to prevent leakage of fumes intothe kiln room.
No electrical connections are required.
The Heatlock keeps the kiln door locked until the kiln has cooled to a safe temperature preventing damage to kiln door and eliminating risk of burning. The lock is discretely positioned adjacent to the interlock key under the door of our front loading kilns; it is operated by a small controller pre-set to lock at 60°C in the heating cycle and to unlock at 55°C on cooling. A warning light indicates when the door is locked, when the light goes out it is safe to open the kiln. The HeatLock is failsafe, if the power is turned off it remains locked, the door can only be opened when powered up and the temperature has dropped to 55°C.
The damper is pre-set to close when the kiln temperature reaches 550°C, it opens again when the kiln cools down to 200°C. There is no need to set the opening and closing temperature and no complicated controller as the temperatures are factory pre-set. The auto-damper eliminates the need to come back to the kiln during firing and removes the risk of the flue remaining open throughout the firing creating a potential hazard.
