Temperatures for Kiln Fusing Glass            

There are different  fuses that you may want to  use to accomplish different effects.  I call them fusing "recipes".  I'll share some that I have used.

 Keep in mind that every kiln is a bit different in how fast it reaches and how it holds temps so you will want to keep an eye on exactly how long to hold to get exactly the amount of fuse you want for the desired effect.

TIP: You can use a bit of Elmer glue watered down to get layered pieces of glass to stay in place. You just have to be sure it's dry before firing or it will muddy your glass.

Use the smallest amount possible.

Photo 1 - tack fuse

1400 degrees for 12 minutes

You can fire just to have a tack fuse where the sharp edges are softened and the pieces are stuck together but all the glass definition is still visible. (Photo 1)

Photo 2 - deeper tack

1400 for 15 minutes

 You may want a  deeper tack with texture but less definition of the texture and individual pieces. (Photo 2)

Photo 3 - full fuse

1450 degrees for 20 minutes

  

To get  a full fuse where all pieces are completely fused and the surface is flat you need a different series of  temperatures and hold times. (Photo 3)
