Irid-on-Irid Fusing

Irid-on-Irid Fusing

Layering iridized glass can be tricky because iridized surfaces will not fuse to each other. With a little clever sandblasting, though, you can create some spectacular designs! For this tutorial, you'll need iridized glass, some masking materials, and a sandblaster. »

Fused Glass “Puddles”

Fused Glass “Puddles”

This may be one of the easiest tutorials we've ever provided - but don't let that fool you. Our fused glass "puddles" will get your mind racing with endless possibilities. For this tutorial, you'll need only the basics - some glass, a kiln, and not much else! »

Some Last Thoughts

The task of creating firings schedules has a reputation for being difficult and, if we are talking about creating firing schedules from scratch, the reputation is well deserved. »

Final Cooling

What it does: Cools your glass to room temperature. »


What it does: Controls the rate of cooling to reduce permanent stress in the glass. »

Rapid Cooling

What it does: Cools your glass to just above the point at which stress can be created. »

Process Stage

What it does: Changes the glass to the desired state. »

Final Heating

What it does: Heats the kiln as fast as possible to get the glass to fusing temperatures. »

Bubble Squeeze

What it does: »

Initial Heating

What it does: Heats the glass from room temperature to about 900° F (482° C). »


With the exception of firing schedules for casting, which are outside the scope of this article, glass fusing schedules can be broken down into these seven phases*: »
