ANNEALERS, Fusers & Crucible furnaces

Annealers, Fusers and Crucible Furnaces designed specifically for and by glassworkers.

Features Include:• Quality Kanthal A-1 heating elements.• Annealing oven heating elements are encased in quartz tubing, making them electrically safe when inserting finished work into oven while it is on.• K-25 insulation bricks insure low heat loss, low cost operation and are more durable industry standard  K-23 bricks.• Average power consumption to maintain temperatures costs only pennies an hour.• Fast heat up times.• Annealers designed for easy one handed operation whether placing finished beads into the annealer or reaching for a preheated glass rod. The finished bead and its mandrel are placed into the annealer through a special front opening making for quick and comfortable operation and eliminating thermal shock.• All bricks are mortared, where appropriate, to insure a long oven life and prevent "dusting" created by loose bricks.• 1 year warranty against defects in materials and workmanship.• Annealers and fusers are also ideal for Precious Metal Clay, enameling, jewelry wax burnout and ceramics to 1900º F.

All annealers and fusers are sold two ways; with and without an infinite control switch. If you order one without the -I extension after the model number, you will also need to add a temperature controller, such as the ASC/3 or ASC/4. Example: AF99. If you order one with the -I extension after the model number, it will have an infinite control switch to allow you to manually control it. Example: KI-AF99-I.You will also need to add a pyrometer to read the temperature. The smaller pyrometer, KI-PYRO-S, is adequate. The larger pyrometer, KI-PYRO-L, has a larger dial and better resolution.

Annealers

The Model AF99's heating chamber is 9" wide by 9" deep by 41¦2" tall. 120 volts, 14 amps, 1680 watts. Reaches annealing temperature in about ten minutes and fuses in about forty minutes. Our most popular annealer, the AF99 is a combination annealer and fuser. The quartz encased heating elements are located in the side walls, near the top. Because of the AF99's height to width ratio, this gives even heat throughout the chamber and allows access through the top as well as through the front opening. The heating chamber can be extended to 9" tall by the addition of the optional extension ring, XR99,but the time it takes to fuse increases to a little over one hour.

As an ANNEALER the heating elements are encased in quartz tubing to make them electrically safe. Placing beads, while still on their mandrel, into an oven with exposed heating elements is like putting a knife into a toaster! Besides a hinged lid, there is a 9" wide by 2" tall front opening that comes with a brick door and also a soft flexible fiber door which makes a complete seal even when the mandrels are long and stick out the opening.

As a FUSER the firing chamber uses the 8" X 8", FS88 fusing shelf. Because the front door is located down low at floor level and the heating elements are safely encased in quartz tubing, raking is very easy and safe: no chance of electrical shock and the door design doesn't allow very much heat to escape and burn your hand.

The Model A1810's heating chamber is 18" wide by 101¦ 2" deep by 31¦2" tall. 120 volts, 14 amps, 1680 watts. The Model A1813's heating chamber is 18" wide by 13" deep by 31¦2" tall. 120 volts, 14 amps, 1680 watts. Reaches annealing temperature in about fifteen minutes and fuses in about three hours. Because of the A1813's low height to width ratio, the four quartz encased heating elements are evenly spaced overhead to give even heat throughout the chamber. Because of the heating element location, the top is hinged from down low, between the firing chamber and the bottom. There is

an 18" wide by 2" tall front opening that comes with two brick doors and also two soft flexible fiber doors which makes a complete seal even when the mandrels are long and stick out the opening. Like the AF99, both the A1810 and the A1813 also can be used as fusers. They are, however, slow when wired for 120 volts. If ordered wired for 240 volts, 14 amps, 3360 watts, the fusing time is cut by more than half. The A1810 uses the 171¦2" X 101¦2 ", FS1017 fusing shelf. The A1813 uses the 171¦2" X 13", FS1317 fusing shelf. Either annealer is great for use in multiple person studios and classrooms.

The Model A1313's heating chamber is 13" wide by 13" deep by 9" tall. 120 volts, 14 amps, 1680 watts. Reaches annealing temperature in about fifteen minutes and fuses in about three hours. Like the A1810 and A1813, the A1313 is available wired for 240 volts.

The quartz encased heating elements are located in the side walls, near the top. Because of the AF1313's height to width ratio, this gives even heat throughout the chamber and allows access through the hinged lid as well as through the 13" wide by 61¦2" tall front opening. The front door is hinged 2" above its bottom and then again at the top of the opening. This lets you open the front door at the bottom only to place small items, such as beads, into the annealer and use the ARR (see below) or fully open the door to place large items into the annealer, such as goblets. Uses the 12" X 12", FS1212 shelf for fusing.

Optional Rod Rest

The Model ARR is specially designed to complement all Arrow Springs annealers, the optional glass rod rest clips onto the front of the annealer at the opening. By placing glass rods onto the rod rest and inserting their ends into the annealer the rods are kept clean and their ends are preheated prior to being introduced into the flame. This virtually eliminates "popping" and greatly reduces the amount of time it takes the glass to become molten. Included is a two tiered Bead and Mandrel Rack for the inside of the annealer to prevent the beads from touching each other or the annealer.

Fusers

The Model F66's heating chamber is 61¦2" wide by 6 1¦2" deep by 41¦2" tall. 120 volts, 14 amps, 1680 watts. Fuses in about twenty-five minutes. A very simple and economical design. Uses a conventional heating element placement, without quartz tubing, and has a lift off lid. Uses the 6" X 6", FS66 fusing shelf.

The Model F99 's heating chamber is 9" wide by 9" deep by 41¦2" tall. 120 volts, 14 amps, 1680 watts. Fuses in about forty minutes. This oven is the same as the AF99, except there is no front door and the heating elements are not encased in quartz tubing. The heating chamber can be extended to 9" tall, by the addition of the optional extension ring, XR99, but the time it takes to fuse increases to a little over one hour.

Electric Crucible Furnaces

We manufacture two crucible furnaces. The CF66-I is a small "Table Top" size that holds a single 31¦2 pound crucible. The CF1515 is substantially larger. It can hold up to five, 5 pound crucibles or one of several available large crucibles with capacities of up to 150 pounds. Both furnaces have an open door "cut out" switch to turn off power to the heating coils when the lid is opened. The lid handle is offset, so it never gets hot. Included is a fiber blanket heat shield to protect the heating elements from dripping glass and reduce heat loss when the lid is open while gathering glass by sealing off the space between the top of the crucible and the brick walls. This saves energy, reduces heat loss recovery time and greatly reduces heat flash to the user.

The Model CF66-I 's heating chamber is 6" wide by 6" deep by 6" tall. 120 volts, 8 amps, 960 watts. Ideal for making marbles, latticino, filigrana, encasing beads and small paperweights and miniature glass blowing. Manually controlled with an infinite control switch. Comes complete with crucible, heat shield and pyrometer.

The Model CF1515's heating chamber is 15" wide by 15" deep by 131¦2" tall. 240 volts, 24 amps, 5760 watts. Has the capacity for large glass blowing and paperweight production. Comes complete with attached ASC/4 temperature controller, 45 pound crucible and heat shield.

Temperature Controllers

The Model ASC/3 is a true digital ramping controller that can store up to 55 segments in permanent memory. The 55 segments allow you to store many user defined firing programs and retrieve for use. This makes the controller quick and easy to use and gives you great flexibility in choosing a firing program for annealing, fusing, Precious Metal Clay, enameling, jewelry wax burnout and ceramics. It is so simple that all you need to do is press a few buttons and it will perform the program and then turn itself off. For your convenience, several programs have already been entered, all of which can be easily changed. If you have special firing programs you use, we will gladly program them into the controller for you. The maximum range of the controller is 2500º Fahrenheit or Celsius. 15 Amps, 120 Volts. 240 volt models available.

The Model ASC/4 is a digital set point controller with a single ramp. It allows you to ramp either up or down to a desired temperature and hold that temperature or automatically turn it off. Extremely easy to use. The maximum range of the controller is 2500º Fahrenheit. 15 Amps, 120 Volts. 240 volt models available.

Both controllers are "STAND ALONE", which means that they are not attached to an oven, have their relay self-contained, have an installed thermocouple and a plug and receptacle. All you need to do is plug the controller into a wall outlet, plug your oven into the controller and insert the thermocouple (temperature sensor) into the oven.
