FuseSchedule

Check COE compatibility before you fire, then get a thickness-matched schedule with a proper anneal so nothing cracks three weeks later.

FuseSchedule solves the two things that ruin fused glass: incompatible COE, and an anneal that was too short.

COMPATIBILITY, BEFORE THE KILN CLOSES Add every part of your piece — sheets, frit, stringers, dichroic. The moment two coefficients of expansion clash, a clear red warning tells you exactly which part to pull. No more discovering the mistake weeks later when the work cracks on the shelf.

A SCHEDULE MATCHED TO YOUR GLASS Choose full fuse, contour, tack, slump, or fire polish, and set your thickness. FuseSchedule builds the whole program: initial ramp, bubble squeeze, process temperature, and an anneal soak and cool rate calculated for how thick your piece actually is.

UNDERSTAND EVERY SEGMENT Each step explains itself in a sentence — why the bubble squeeze exists, why the anneal takes as long as it does. A temperature-time curve shows the whole run with the anneal marked.

LOG WHAT ACTUALLY HAPPENED Record the program you ran, a result photo, and any problems — bubbles, devitrification, cracks — so you can dial in your own kiln over time. Every kiln fires a little differently; yours will tell you how.

GLASS FAMILIES COE 90 (Bullseye), COE 96 (System 96 / Oceanside), and COE 104 (Effetre / lampwork). Mix manufacturers freely within the same COE.

A NOTE ON ACCURACY Schedules are a well-founded starting point, not a guarantee. Glass behaviour varies by manufacturer, batch, kiln, and piece — log your results and adjust. Never shortcut the anneal.
