Firing Schedule Calculator

The Firing Schedule Calculator helps you create a starting firing schedule for common glass fusing projects. It can generate suggested ramp rates, target temperatures, hold times, annealing stages, and cooling stages based on the type of glass, project thickness, project size, firing goal, and the level of caution you want to use.

The calculator is designed to be useful for planning full fuse, tack fuse, slump, and related kiln work. It can help you compare firing approaches, adjust for thicker projects, and choose a more standard or more conservative schedule depending on your glass and kiln situation.

The schedules produced by this calculator are intended as practical starting points only. Every kiln fires differently, and results can vary depending on kiln size, element placement, shelf setup, glass colour, glass compatibility, mould type, project thickness, and how the kiln has been loaded. Always check the glass manufacturer’s recommendations, keep your own firing notes, and test unfamiliar combinations before using them on an important project.

This calculator does not guarantee a successful firing. It is a planning aid for glass fusers, not a substitute for experience, kiln testing, manufacturer instructions, or safe studio practice.
