In 2015, Alfred University chose Bailey Thermal Logic Electric Front Loading kilns to outfit their department. This is the first time in their history where they selected a manufactured front loading electric kiln for their kiln room instead of building their own electric kilns. They ordered a total of seven Thermal Logics Electric Kilns, including a 61" interior sculpture front loading electric kiln and a 51" interior 2 car shuttle electric kiln. The Alfred kilns run constantly, and they demand the very best in dependable performance. The Alfred staff saw great benefit to the Bailey hard element holder system, and all the other features of sustainable electric kilns design.
The Bailey Thermal Logic is undoubtedly the best electric kiln ever built!
Sometimes a product comes along that stands way out from the pack because there are so many improvements and innovations. The Bailey Thermal Logic Electric Kiln is one those products.
Bailey just redefined the standards for excellence in large electric kiln design. Not just by a little, but by a lot. The Bailey Thermal Logic Electric Kilns are a sustainable kiln design, built for a lifetime of heavy use.

Imagine a hard element holder so strong that it can withstand over 22 lbs of direct force and not fracture or chip.
Imagine this same super strong hard element holder being able to be lifted out instantly! If you need to inspect an element, remove debris, or if a glazed ceramic piece accidentally fuses to it, you won't have a problem. You can inspect or replace the ingenious Bailey hard element holder in seconds. No tools, no complications. Innovation at it's best!
Consider what this means. Now the most vulnerable part of the kiln, the element retention system, is incredibly strong and easily serviced. You can keep your kiln looking as good as new indefinitely. This is pure Bailey logic.
Here is another huge benefit of the Bailey Hard Element Holder system: Better Heat Transfer. Look at the illustration and note that every element slot in the brick has been cut at a unique 90 degree angle. The radiant heat from the element and hard element holder can fan right out to provide maximum exposure into the load. This greatly improves heating efficiency. Other front loading kilns have their elements buried in the brick. That causes the heat from the elements to absorb into the insulation bricks quickly, saturating them, and so diminishing the IFB insulating capabilities and increasing the heat loss. The Bailey energy saver design further promotes energy efficiency by keeping the elements on the interior face of the brick. Note how the Bailey hard element holders and elements are not buried in the brick, and how they extend into the kiln chamber so they can radiate their heat immediately into the load. Brilliant!
Thermal Logic elements are massive, about 5/8" in diameter!. Just compare the size of the Thermal Logic Electric Kiln to your typical competitor's elements.
We use thicker wire, and more of it for extra acceleration power. It's like having a bigger engine under the hood. We also calculate the elements so there is less stress on the wire as it heats. You might call it a "cooler burn" because instead of making less wire work harder, we have more wire working less. The end result is much longer element life and a kiln built for speed. You spend more initially, and save dramatically long range.
How many times have you scraped your hands on the wall of a kiln, or bumped the wall with the shelf as you stacked the load? Plenty! No wonder, there isn't enough room! The walls of the typical electric kiln get damaged as a result of stacking in a cramped space. Bailey has implemented a very logical concept... it's called "more room". By leaving 2" from the wall to the shelf, stacking becomes much easier. Not only do you protect your hands and the walls, it promotes better heat uniformity in the chamber.
Even if bricks are damaged, no problem. Bailey designed the kiln without mortar. With the Bailey Easy Repair system, fevery brick in the wall or floor can be removed and replaced no matter where it is, and without dismantling the entire kiln. How is this possible? Bailey secures all the kiln brick with pressure systems and unique external anchors that are easily assessable. The result is a truly sustainable kiln, with an easy repair system designed to last forever because it is so easily serviced.
This is another "easy repair system" of the Bailey Electric Kilns. The bricks on the front loader side walls are always the most vulnerable. Students often damage them from repeated impacts from shelves as the kiln is loaded and unloaded. If the walls are mortared together, you have no way to repair it. Bailey has engineered a new way to secure the front wall brick so they can be easily changed in a matter of minutes. This keeps your heat seals positive and protects the frame.
Another Bailey innovation is the front fiber roof gasket. This lead gasket has a dot pattern made of a hard ceramic material that protects the fiber and prevents abrasion. It is also designed to allow the fiber gasket to remain flexible so it won't crack as the door compresses against it and is secured prior to firing. This top horizontal gasket is designed for fast convenient replacement. It only takes a couple of minutes and no mortar is required.
The Thermal Logic has stainless steel edge protectors that guard against side impacts against the brick. This is another area that often experiences collision and damage during countless loading and unloading procedures. The stainless steel edge protectors absorb the impact so the brick remains unharmed.
Each spy port has a stainless hood directly above it which collects escaping fumes and heat. The heat and fume is channeled into the spy hood and directed above into the overhead residual hood. This is the most comprehensive ventilation system that provided complete fume removal.
What a great idea! Bailey has innovated another first, the built in UV shields. Now you don't have to go searching for UV glasses to view the cones. Each UV shield is sandwiches between protective clear Shields, and the stainless steel outer frame pivots up so you can withdraw the spy plug for viewing the cones. Note: The spy plug was removed for this photo, but should only be removed momentarily for viewing cones and put back promptly.
(A) Mounted Residual Draft Inducer (optional)(B) The residual hood overlaps the door and fastens to the top of the kiln. All of the exterior walls of the kiln are hollow. Air intakes at the bottom of every exterior wall and door cavity so the heat travels out the top of the frame and directly into the collection hood. Residual fumes are also collected from the door and spy hoods. An (optional) draft inducer is needed to pull away the fumes to the outside if you don't have an existing appropriate draft system in your facility.
The motor for the residual fume removal can be controlled by the Bailey Thermal Logic Controller. See below for information.
(C) Negative Pressure Mount Package (optional)(D) The Negative Pressure Fume Vent pulls firing fumes directly from the inner kiln chamber as the firing progresses. It extracts noxious fumes that may accumulate during the firing, keeping the classroom air clean, while protecting the outer frame from corrosion. You can buy the premounted package with the sheet metal vertical chase and high exit for the pipe, or just the standard Negative Pressure Unit for attaching to an existing kiln room wall. A flexible hose (included) is stretched to connect the rear of the kiln to the Negative Pressure Unit. The operation of the Negative Pressure Unit can be controlled by the Bailey Thermal Logic Controller when the(optional) AC outlet feature is ordered. See below.
(E) The thermocouples are serviced from outside the main control panel. This makes it easy to change a thermocouple during the firing. A Plexiglass pivoting cover locks the thermocouple in position.
When the (optional) AC Outlet box is ordered, the Bailey Thermal Logic Controller can be programmed to switch both the Residual and Negative Pressure fans on and off to synchronize with the firing. The AC outlet also is convenient so the blowers can be unplugged if they need servicing. A green panel light is also included with this package and will illuminate when the fume systems are active.
Without the AC controlled outlet, the user must manually turn the fume extraction devices on and off.
There's more than meets the eye! Like the main frame of the kiln, all the bricks in the Bailey door are held under compression with ingenious methods of spring loaded compression. No mortar is used. You can adjust bricks to get a perfect heat seal, and you can replace bricks at any time. Future service is made simple.
Most larger models of the Thermal Logic Electric will have elements in the door. Some kilns don't require a door element for heat uniformity or heating.
The spy ports are larger than the small round style, so you have an easier job viewing the cones. The inner wall of the port is beveled so you can have a wider view. The top and bottom of the ports are made of alumina shelf so there won't be abrasion from the spy plug removal and replacement over the years. The exterior of the door has the hollow wall cavity so heat is directed into the residual hood for efficient removal.
NOTE: Bailey doesn't use fiber doors as we find in school situations that fiber is not well suited. It is easily damaged, and can be over compressed. The door area is a high activity zone where it is easy to brush up against. Putting a hard coating on the fiber is superficial at best, and there are future issues of shearing off. Insulating firebrick is ideal. It is an equal insulator, it is resilient to rubbing against, bumping, and impacts. We have coated the IFB doors (without elements) with an emissivity reflective surface to enhance the energy efficiency.
For safety, a limit switch is located at the bottom of the door to turn the power off to all elements once the door is cracked open.
Bailey has innovated an above floor element system for better firing efficiency. Since the element is situated above the floor, the heat radiated by the element goes directly into the load instead of radiating it directly into the insulating brick. The element is so simple to replace, it just wraps around high alumina posts that define the pattern you see. Protective alumina tubes are used to prevent glaze from being accidentally dropped onto the element at the side wall (where the element feeds into the master control box). The entire wrap of the element is protected once the bottom shelves are in place. The bottom posts (1-3/8" high x 2.25" square) are included. Note: Some models of smaller kilns do not need a base element.
When you eventually need to service an electric kiln, you appreciate it when the manufacturer makes your job easier. That's exactly what we have done. The large control panel hinges open to provide ample room to maneuver to all of the components. Every wire is individually numbered, and a wiring diagram is attached inside every unit. The Thermal Logic circuitry is really a thing of beauty. Fuses, relays, elements junctions, and contactors are all nicely organized and accessible. Electrician's smile when they open our panel, because they appreciate the meticulous care in the design and layout of our circuitry layout. We make their job easier.
All of our designs start with a shelf pattern. The options for stacking loads are:
Each shelf pattern has a 2" clearance from the wall the load (Load = shelf pattern x height). Some companies rate a kiln by the total interior size of the chamber, not the actual payload area where you place your kiln furniture and pottery.
Bailey provides extra tolerance from the wall to the shelf for easy accurate placement of shelves when stacking and better heat transfer. Consequently, there is slightly more chamber space that is left open. You can’t put larger shelves in a kiln designed for a smaller shelf size. The reason is, we have calculated the BTU’s necessary (watts per square foot) to heat the kiln “load” properly. The shelf area with pots are the “load”, which is a mass that has to be heated up. This requires a ratio of BTU’s to heat in up in a timely fashion. If you did use a larger shelf to place more pots, it would throw the ratio of power to load off, thus slowing down the kilns heat building properties.
