Instant gratification
Place the MagicFuse kiln inside your
microwave oven and turn on the power. The kiln will reach 1500°F
(815°C) in about 5 - 8 minutes. (Firing time depends on the wattage
and brand of the microwave oven.)
Learning to fuse glass
Firing the MagicFuse requires skill.
Because the kiln fires so rapidly, glass pieces should be limited in size
to 2 layers of 1 ½” x 1 ½” or smaller. Larger sizes or additional
layers of glass must be pre-heated for 5 minutes at a 50% power setting on
the microwave. Otherwise the glass will break.
Annealing in a separate kiln is unnecessary for
small glass pieces such as earrings and small pendants. The glass must
also be free of glue, grease, and fingerprints. The rapid firing of these
contaminants can cause the glass to break.
Firing times may vary even within the same
microwave oven. The firing time varies from one microwave to the next, and
a MagicFuse kiln that is still warm from a previous firing takes less time
to fire than a cold kiln. For these reasons, visually check the glass a
minute or two before it is done. Then fire longer and check it again.
Remove the kiln when the glass has fused just the way you had envisioned.
The glass begins to fuse during the last 30 seconds of firing. This is why
precise fusing is much easier by visually inspecting the glass.
The microwave oven
The MagicFuse requires a microwave oven, which
is not included. The firing time and condition described here are for a typical 1100 watt microwave oven.
Since the MagicFuse does not contain heating elements, the specs will vary depending on the microwave you own.
If you remove the MagicFuse kiln after the glass
has fused, the heat will not build up inside the microwave oven. The
MagicFuse reaches higher temperatures than you will ever encounter in your
kitchen. But the firing is so rapid that the heat does not have time to
work its way to the outside surface of the kiln.
You can fire the MagicFuse in the same microwave
oven you use for cooking as long as you clean the microwave oven after
each fusing session. If, however, you fire ceramic fiber paper, you might
want to fire glass in a separate oven. This is because the fiber paper
produces fumes.
Controlling heat distribution
Firing the MagicFuse kiln on the microwave's
food rotator tray produces better heat distribution inside the kiln than
firing without the tray. However, in some microwaves the rotator tray
jerks as it turns, moving glass pieces out of position. If this is a
problem with your microwave, either use a different microwave, or remove
the rotator tray and rollers from the microwave. If you cannot remove the
rotator parts, then turn the rotator tray upside-down, and place 3 of the
½" ceramic posts that came with your kiln on the tray.
Accessories included with the kiln
Includes 6 - ½” ceramic posts, glass
separator, and a 15-page 5 1/2” x 8 1/2” instruction manual. You can
read the manual on-line by clicking here.
Place the kiln on 3 posts inside the microwave and on the other 3
posts for cooling.
Extra supplies you will need
Microwave oven with metal interior that is at
least 8" tall inside, 12" x 12" ceramic tile or ceramic
kiln shelf, heat-resistant gloves, 1" paint brush for applying glass
separator, notebook for keeping firing records, glass cutter, and clear
safety glasses.
