Spotlight on: Fused Glass

Even though I work with glass I rarely do fusing. Not for lack of wanting to, but the hubby says no to the cost of a kiln. 🙁 Guess I have enough glass toys. For now.

Glass fusing refers to glass that has been fired in a kiln. There are 3 levels of fusing and it goes by degree of temperature. The first level is slumping, which basically makes the glass melt into the shape of the mold it is placed on top of. This is the lowest of the temperatures, at a cool 1,099–1,251 °F.

Here is an example of a slumped dish that was made by DiSKoGiRL. It has such unique colors that make it gorgeous.

We have all seen those wine bottles that have been flattened, right? Slumping is the process used on glass bottles like these from joby560. Great for use as a small serving tray.

The second level is called tack fusing, and this is when you heat the glass enough to “glue” pieces of together. This occurs at temperatures 1,251–1,350 °F. In this example of tack fusing joby560 creates some bright and cheery suncatchers.

Last is a full on fuse and the temperatures are 1,350–1,501 °F. These pendants by TickleTickle are so pretty and delicate looking for something created with such high temperatures.

If you’re interested in trying glass and glass fusing, but don’t want to spend thousands, there is such a thing as a microwave kiln. They are fairly inexpensive and can give you a chance to try glass on small scale.

To do more reading/research here is a microwave kiln thread from our glass boards to give you first hand information.

Thank you for checking out the spotlight! Let me know if you have ideas for future topics to inform you about there awesomeness.

    I love all things glass and really want to try some fusing. In my research I’ve found that many owners of kilns are willing to fire a piece here and there for others at a reasonable rate. It is possible to find someone who can accommodate a larger piece, if that’s what you have in mind, and potentially less expensive than buying even a microwave set up for yourself (depending on use, of course).

    You can also check at local colleges for rental time when they fire.

    Thanks for reading CLM.
