There are several good choices on small enameling kilns. The first
is an electric kiln which looks like a beehive. You are limited to
very small items and the heating is pretty uniform if the metal
cover is placed over the piece. With a kiln without a temperature
controller, you need to use care not to over heat your enamels or
melt your items.
Next you have the microwave kiln you asked about. These actually
come in a couple sizes. They take from 2 1/2 minutes to around 5
minutes in a microwave oven, depending on the strength of the oven.
Do be careful taking these in and out of your microwave as the top
glory hole has a tremendous amount of heat comming from it. Moving
these in and out of a microwave should be done with care as the
interior of the kiln is extremely hot. That said they work very well
for small projects.
The next option is either a PMC or small enameling kiln. Some have
programmers built in, and regulate the temperature of the kiln and
the melting enamel very accurately. These run from $570 - $630.00
USD for the small kilns. The advantage with these is you can do
small pendants and rings up to small bowls and light switch cover
sizes. They offer a lot more versatility and at an affordable price
can also be used for PMC.
