The ability to melt glass can be a huge plus for jewelry makers and other artisans. You could use a traditional kiln to melt glass, but a traditional kiln is out of the price range of the majority of hobbyists and crafters. Wouldn’t it be great if you could melt glass in the microwave? As it turns out, with a microwave kiln, you can.
微波炉窑使您能够快速、轻松地melt glass for making jewelry and other craft projects. Essentially, it is an insulated box wrapped around an inner liner that heats up when exposed to microwaves. To use a microwave kiln, simply place the glass to be melted within the kiln. Secure the cover and place it in a dedicated microwave.
Before we delve into the features of microwave kilns, let’s examine one very important point that must be understood: microwave kilns are not designed to make pottery.
If you are looking for a traditional kiln to fire clay pots or other types of pottery, you need a freestanding kiln designed specifically for that purpose. Traditional kilns get much hotter than microwave kilns. They also tend to cost a lot more.
The commonality between microwave kilns and traditional kilns lies in the use of the word “kiln,” which is defined by Merriam-Webster as a heated enclosure in which you can burn, fire, or dry material. Importantly, not every “kiln” is suitable for making clay pots.
Microwave kilns have been around for about 20 years. While the technology hasn’t changed much over this period, the price has definitely dropped.
微波窑并不大。你不会逃跑g a major jewelry operation with one of these, though some are bigger than others. The outside dimensions start out around 3 1/4 x 4 1/2 inches and top out around 4 1/2 x 7 1/2 inches in size. Notably, the inner fusing platform can be much smaller and is often no more than 2 1/4 inches wide.
If you are interested in working with larger pieces of jewelry, we suggest a larger kiln. Note, however, that these kilns are less portable, and consumers with small microwaves may have a harder time fitting the kiln inside. It’s a good idea tomeasurethe interior dimensions of your microwave before ordering a microwave kiln.
The majority of microwave kilns are quite similar to one another. Therefore, it can be hard to distinguish which ones rise to the top in terms of durability. But some do. A common complaint regarding poorly built kilns is that cracks form in the walls after limited use.
Microwave kilns are easy to use but difficult to master. Some include detailed directions and/or access to instructional videos; others offer minimal instructions on how to use the kiln. Some melt glass quickly; others take longer. Uneven heating is a potential issue that could affect every firing.
A microwave kiln consists of an outside casing and an inside housing. The outside part of the kiln is usually made from some form of white fiber, which acts as insulation for the heat created on the inside. The white fiber contains the heat and also makes the kiln easier to handle when hot.
The inside of the kiln is where the action happens. The susceptor material heats up when exposed to microwaves. It is typically black and consists of some type of graphite, magnetite, or a similar material.
Lower price:In the$25 to $30price range, you will find small, simple kilns that sell with few or no accessories. While you are limited as to how much glass you can fire at a time, kilns in this range are ideal for someone seeking to dabble with a microwave kiln. For a larger kiln, consider something in the $30 to $40 range.
Higher price:Kilns at higher price points(over $40)usually include some form of a starter kit. For example, you might get a 10- to 15-piece collection of glass samples along with tools and kiln paper for the higher price. If you look in the $50+ price range, you will find microwave kilns that are great for experienced jewelers as well as those who are new and eager.
Practice makes perfect. Consider keeping a firing log to track your accomplishments so your skills will improve.
A.You might just get the kiln, or you might get a starter kit. Check the specs before opening your wallet. A starter kit is helpful if you need supplies, though it will come at a higher price.
Some items you might find in a microwave kiln starter kit include the following:
A.There is no blanket answer to this question; it depends on a variety of factors. Glass by itself is not affected by the heat of a microwave, which is why you need the kiln to heat it to a melting temperature. Thoroughly read all instructions packaged with the microwave kiln and adhere to all safety recommendations.
A.These kilns can typically reach temperatures in excess of 1600°F. In other words, really, really hot! As such, this isn’t a device that should be used by unsupervised children. Anyone using one of these should be wearing safety glasses and heat-resistant gloves to protect their eyes and hands.
When moving or checking a hot microwave kiln, keep it at arm’s length, and definitely keep it away from your face. A hot kiln should also be kept away from flammable objects and placed on a heat-proof surface. In addition, be sure to keep a hot kiln away from overhanging cabinets.
A.The included specs should include directions for recommended microwave settings. Manufacturers typically recommend that you use these on a higher microwave setting, with 1,000 watts or so being optimal. That said, you can use a microwave kiln in a lower-watt microwave, but it may take longer to melt glass.
