Uroboros and Spectrum System 96 glass full fuse firing schedule

Today I thought I'd share my favorite firing schedule for Uroboros glass (it works great for Spectrum 96 COE too).  This is for full fusing two layer pieces.

300° - 1150°  hold 30 minutes

200° - 1370° hold 20 minutes

400° - 1470° hold 5 minutes

9999° - 950° hold 60 minutes

150° - 800° hold 10 minutes

300° - 500° no hold

You will notice that when fusing transparent glass you will not need as much heat as firing opaque glass.  It is only a matter of a few degrees.  You can tell if you need to turn down the heat used on your highest full fuse temperature segment if you have small glass burrs sticking out on the sides of your finished piece.

It is advised to try this schedule with your kiln on a test piece first to make sure it is good for your kiln!  Kilns don't always heat up to the same temperatures as other kilns do.  If your finished fused product seems slightly indented or distorted on the side edges, you need to turn down the high temperature.  Mine is 1470° (hold 5 minutes).  You might want to program your kiln to heat up to 1450 instead and perhaps hold longer.  Again test your glass sample first before firing your good piece!
