Basic Glass Fusing With Dichroic

The first thing to remember when fusing dichroic glass is that, like all glass used in glass fusing, it must be compatible. Regular window or float glass is generally incompatible, so it should be avoided.

Take a look at some glass suppliers and explore their selection of patterns. Along with the description, you will see that each piece of glass has a COE number, usually 104 or 90. You must fuse the glass with glass from the same COE and must not cross them. Mixing the COE results breaks as the glass expands and contracts during the cooking process.

COE, or the coefficient of expansion, is simply a measure of the degree of expansion that glass passes through as it is heated.

CBS Patterned Dichroic Glass can come in either a clear or black base. In black it can be used as a base. It is best to use it on a darker base as the coating can become almost invisible in sunlight.

If you are using more than one layer of dichroic glass, you must remember that the coated sides must not touch each other. Remember that the coating is a metal oxide. Having two of these directly connected means that the glass cannot fuse properly, resulting in ruined patterns of deformed glass.

Glass coating is more delicate than art glass, although it is compatible with most. Generally speaking, it should not be taken at temperatures of 810 degrees Celsius, although personally shooting above 800 is considered risky. However, temperatures can vary greatly from oven to oven. Be careful when using glue with dichroic glass. Overuse can cause the liner to spoil as it burns in the oven.

 

Buying A Kiln For Glass Fusing

Some important things you need when conducting the process of glass fusing is a pyrometer. What is a pyrometer? It tells you the temperature inside the kiln. Although it does not tell you the temperature of the glass, the air temperature gives the general temperature of your glass.

If you do not know what the temperature is inside, you do not have a clue about what happened in your glass. Every kiln is different and unique. You may read more about it in the beginners guide to Kiln-Formed Glass by Brenda Griffith.

There was no viewing window. Most kilns do not have a display window, and it was fine for smelting. If you do not have a pyrometer, then it is a must to have a window so you can at least see what's going on inside the kiln. But, this kiln did have a peephole, which is located at the top of the kiln.

A kiln shelf is not provided for this kiln. A kiln shelf does not need to do glass fusing, but it is very helpful to have air circulation around your glass pieces. Air circulation helps to ensure that your glass is heating at an even temperature.

Kiln had a digital control button. It is fantastic, but when using the digital keys, you must constantly observe your pieces to make sure to get the desired effect. When teaching a classroom full of students, there is no time to stand oversees a furnace.
