Pearl-4426 Professional Glass Kiln

The sleek Pearl 4426 Professional Series glass kiln is exciting to look at and to operate. It will help to unlock your potential as a glass artist. The kiln is an investment that pays for itself by firing large glass panels or production loads of small pieces. Imagine how many dichroic pendants you could fire in one load! The Pearl-4426 is proudly made in America by skilled workers, some with decades of experience. This deluxe kiln is designed for those whose livelihood depends on reliable glass production.

Assemble glass inside the firing chamber

The Pearl4426 top lifts away to give convenient access to the shelf area. Heavy-duty air pistons lighten the top. The lid handle is 50” long for convenient opening. Assemble glass pieces directly on the 42” x 24” CoreLite shelf (Optional Furniture Kit) that you have already positioned inside the kiln. A woven rope seal mounted on all four sides of the lid acts as a gasket and cushions the top. The mating surfaces between the lid and sidewalls are hardened and sealed with a special refractory coating.

Quartz element tubes

The lid elements are protected in six quartz tubes for a cleaner kiln interior. There is less dust in the kiln, because there are no element grooves; the firebrick top is one continuous, smooth surface. The quartz tubes protect the elements from contamination with foreign materials that could shorten the element life. The quartz tubes absorb very little heat, allowing the elements to heat the firing chamber efficiently. Quartz tubes protect the user from contact with the elements.

Elements in the top and sides

For even heat distribution, the Pearl-4426 includes two rows of sidewall elements, which are mounted in the top section that lifts up with the lid when the kiln is opened. The sidewall element coils are protected in dropped, recessed grooves.

Long-lasting mercury relays

The Pearl-44 includes features not found on most competitive kilns. For instance, mercury relays are standard on this kiln. Relays send power to the elements on command from the digital controller. Industrial-grade mercury relays found in the Pearl-4426 far outlast mechanical relays. The life of the quiet, reliable mercury relay has been measured in millions of on/off cycles.

Heavy duty kiln

The Pearl-4426 has 3” thick firebrick sidewalls, bottom and top. (This is 1/2” thicker than the firebricks in some competitive kilns on the market.) For long life, the kiln has a 1/2” ceramic fiber expansion joint in the center of the firebrick top and bottom. The heavy tubular frame gives the firing chamber rock-steady support.

The Pearl 4426 kiln is now built standard with deluxe heavy duty locking casters for easy moving of the kiln (not pictured, but included).

To keep the electrical components cool, they are mounted inside a ventilated switch box with a double heat shield and air gap between the kiln and box. Costly heavy-gauge nickel-plated copper wiring is covered with high temperature glass-braided insulation.

Easy maintenance

The beautiful Pearl-44 is designed for easy maintenance. You can quickly remove the top and front sections of the control panel for easy access to the electrical components. The electrical parts are thoughtfully laid out for quick maintenance inside the large control panel. The ventilation slots keep the control panel cool. The control panel includes an on/off switch and two pilot lights.

Special limit thermocouple for greater accuracy

The thermocouple, which is the rod that extends into the firing chamber, senses the temperature, so it is critically important to your firings. The Pearl-4426 comes with a ¼” wide Type-K made with special limit wire for accuracy. The tip of the thermocouple is exposed, which results in rapid temperature response time. The new and improved thermocouple replaces our earlier sheathed thermocouple. The new thermocouple is made in America to our exacting standards.

Environmentally Friendly Paint

The Pearl-44 has a durable high temperature, water-base finish. We chose water-base paint because of the low emissions during spraying. This creates a safer working environment for our employees and cuts down on pollution.
