Webabout 550 C lower than the onset temperature (∼ 4250 C) for nucleation for this LS 2 glass, and no nuclei is expected to form when the glass is heated at 3700 C. However, the DTA results in Fig. 6 indicate the formation of additional nuclei at the tip of the bent glass fibers, presumably due to a lowering of viscosity WebNov 1, 2024 · The nucleation curve of glass 27.0 heated at 743°C is shown in Fig. 10 together with the curve for glasses 28.3A and 28.3B. The nucleation rate of glass 27.0 increases up to about 2 h and reaches a steady-state regime. After these periods, the nucleation rates of the three glasses are constant and equal. 3.1.2.
