WebThe temperature is held at 1000° for 20 minutes to allow the heat to soak entirely into the glass. Segment 2 RAMP UP Temperature increased at 400° per hour up to 1150°. Segment 2 SOAK Temperature is held at 1150° to allow the escape of any air that might be trapped between the layers of glass or between the bottom glass and the kiln shelf. 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. WebNov 1, 2016 · The annealing range that I work with has a very broad range, from 900F to 1000F. Higher annealing temperatures can cause surface luster oxidation (burn-off) in reduction colors, and color shift (over-striking) in striking colors. Annealing is a time/temperature relationship.
