Microwave Kilns

Microwave Kilns

The microwave kilns are normally used during the manufacture of glass jewelry, small clay and silver clay products. These ceramic-based kilns are made of refractory board. This material is used to manufacture several other kilns. It makes microwave ovens’ insulating units to protect the oven from high temperatures. To create the heat useful to fire the clay and glazes, the systems combines microwave energy and closed kiln effects. Use of this type of a kiln is rather simple and direct.

 

What are the merits of using microwave Kilns?

• A microwave kiln is about ten times inexpensive compared to a usual kiln.
• It can control the level of fusing for every unit
• In less that fifteen minutes microwave furnaces achieves good fusing results
• In terms of energy consumption, microwave ovens are about twenty thousand times cheaper.

A few demerits associated with the use of microwave kilns

• You can only make a few units of ceramics at a time. This particularly happens if you have bought the smallest kiln.
• You must wait for every unit to cool to the room temperature range before you can use a kiln system another time
• In half an hour to one hour, your glass, clay or other silver clay items will cool down. This means you cannot perform any task on them or reuse the kiln.

There are different sizes of microwave kilns to go for. These include the following:

• Medium size kiln- written in short form as MK-M, a medium microwave oven measures seventeen centimeters in diameter by eight point-seven centimeters high. The inner section measures eleven centimeters in diameter by four point-five high. Those who are about to start glass jewelry art often buy this kiln. In minutes the users are able to fuse numerous pieces of glass using the microwave energy. It is easy to master how to operate it. Mostly, this type of an oven breaks its base. You shouldn’t worry about it because the spare parts are available.
   
• Small size kiln- if you do not want to buy a medium microwave furnace, a small kiln or the MK-S is a good alternative. Externally it measures twelve point-five centimeters in diameter by six point-five centimeters high. Internally it measures eight centimeters in diameter by four point-five centimeters high.  Within minutes, you can create art items even as a beginner. If its small base is damaged, you can always replace it. All you have to do is to conduct a thorough research online. Many stores do not only sell MK-S kilns but also their spare parts.

More tips about the microwave oven

• To keep the oven from burning out, allow it to cool for at least twenty minutes between uses.
• Never place dirty materials in the oven especially oil to avoid causing fire.
• Fire only dry items and use the lowest temperatures possible. It is okay to perform extra firing later.
• Repair and maintain your microwave kilns often especially on the interior to avoid cracks.
