Firing with Inclusions requires you to adjust your firing schedule. By slowing down the ramp rates and adding a hold in the slumping range, you can accomplish a ‘bubble squeeze’ and encourage the air to escape as the glass fuses. Here is an adjusted fusing schedule for example:
|Ramp Rate (F)||Hold Temp (F)||Hold Time|
|250||1300||10 min – 40 min||Bubble Squeeze Hold|
|off to room temp|
This is a sample firing schedule for float glass, it WILL NEED TO BE TESTED AND ADJUSTED! There are many variables that will effect your firing success, including glass thickness, inclusion thickness, kiln size, etc. I’m always happy to help with adjustments, give this schedule a try, then send me photos via the contact form and I can offer suggestions.
Some examples of projects using this firing schedule:
