(System 96®) Firing
Schedules - Celsius
Temperatures and hold times in the following schedules should be considered starting points; you will want to adjust them
as necessary to achieve your desired effects. (See Forming Stages below for additional guidance.) Please keep in mind
that no one firing schedule will work for all projects. Specifics such as project size, number of layers, style of glass, desired
finished shape and texture should all be considered when choosing the right firing schedule.

Oceanside Compatible Forming Stages
Forming Stages information is provided to help users understand the melting characteristics of Oceanside Compatible
products. The temperatures provided are estimates for common kilns firing a project about 30 cm diameter or square,
consisting of two full glass layers and a third design layer (fired thickness about (6mm)).
Use these guidelines as a starting place, then make adjustments to obtain the desired results for your specific project
using your unique equipment. Temperatures are given in degrees Celsius.
DESCRIPTION BEHAVIOR
Slump
TEMP
Previously fused project softens and slumps to take the shape of a selected form or mold.
660º-675º
Separate glass layers are fused together with little deformation beyond softening or rounding of edges.
732º-743º
Contour Fuse
Separate glass layers are fused together, edges are soft and rounded, project surface retains a degree of
dimension desired by the artist. (Any degree beyond Tack but not yet Full fused.)
760º-780º
Full Fuse
Separate glass layers are completely conjoined into a single uniform layer, top surface is smooth and void
of dimension or relief.
793º-802º
Combing
Recommended temperature for a 10mm thick combing.
904º-927º
Tack Fuse

*At the Anneal Point of a glass, internal stresses are largely relieved in a matter of minutes. At the Strain Point,
internal stresses are substantially relieved in a matter of hours.
