Glass annealing temperature chart
Did you know?
WebThe glass-transition temperature Tg of a material characterizes the range of temperatures over which this glass transition occurs (as an experimental definition, typically marked as 100 s of relaxation time). It is always lower than the melting temperature, Tm, of the crystalline state of the material, if one exists. WebThe next stage is Annealing. Choose the optimum temperature recommended by the glassmaker (950 F for System 96, 900 F for Bullseye), and it’s safe to drop to that temperature at a high rate. Fleeing the forming range of temperatures quickly will also help prevent over-forming.

WebRepeat the process until the temperature stays close to 1000° when the lid is replaced. Replace the lid and turn kiln on low for 20 minutes. This will keep the kiln approximately 1000 - 1200°, allowing a minimal annealing cycle. Turn off the kiln and cool naturally to room temperature.
