Choose the type of metal you want to use. Copper, brass, gold and silver can all be fused to glass. However, while brass maintains its color, copper turns a rust-red color when fused. Silver and gold may be a little more expensive, but they can fuse permanently onto glass without the need of a protective glue. Aluminum will not work because it melts at much lower temperatures than glass.
Clean off any fingerprints or marks on you glass and metal. You can use rubbing alcohol or regular water. If you leave prints or marks on your glass or metal, they will be fused permanently into your art.
Glue the metal chain in the place you want it on the glass. To do this, use a regular white glue, and use only as much as you need. This glue, if used sparingly, burns clear off of glass and metal.
Heat your kiln to 1,500 degrees Fahrenheit (815 degrees Celsius). Place your piece on the shelf of your kiln, and let it heat for about 15 minutes. This is about the time it takes to soften glass. Watch your piece to make sure the glass has softened, but is not melting or collapsing.
Drop down the temperature in your kiln to about 975 degrees F (523 degrees Celsius). This is the "annealing" stage, in which glass must be cooled slowly. Keep glass cooling at this temperature for about four minutes.
Drop down the temperature in your kiln to about 900 degrees F (482 Celsius). This is the "strain point" in which internal strain on the glass is relieved. Let your fused art sit at this temperature for about four hours.
Turn off the kiln and let your kiln cool naturally. When the kiln and glass have cooled, your piece will be done.
