[0117] (4) Place the series of pre - formed glasses into an annealing furnace for annealing treatment to obtain a series of lithium aluminosilicate glasses, and conduct performance analysis on the series of lithium aluminosilicate glasses.

[0118] After annealing, observe the apparent quality of the series of lithium aluminosilicate glasses, and the results are shown in Table 5. It can be seen from the data in Table 5 that when the stirring time is the same, when the rotation speed is lower, there are more bubbles in the glass; the longer the stirring time, the better the apparent quality of the glass.

[0122] Comparative Example 1

[0123] The difference from Example 2 is that in step (2), the transmission gear 5 is not turned on, and the furnace wall 4 does not rotate. In step (5), the cast and formed glass is placed in an annealing furnace. After annealing, the glass is taken out for observation, and stripes appear in some of the glass.

[0124] After annealing, chemical strengthening is carried out in a mixed molten salt of 85 wt% KNO3 and 15 wt% NaNO3 at 420 °C for 8 h, and the surface compressive stress (CS) and the depth of the stress layer (DOL) of the glass are measured. The results are shown in Table 8. It can be seen from the data in Table 8 that the CS and DOL of the glass with stripes decrease.

[0127] Comparative Example 2

[0128] The difference from Example 2 is that the homogenization unit is not started. In step (5), the cast and formed glass is placed in an annealing furnace. After annealing, the glass is taken out for observation, and there are many bubbles in all of the glass.

[0129] After annealing, chemical strengthening is carried out in a mixed molten salt of 85 wt% KNO3 and 15 wt% NaNO3 at 420 °C for 8 h, and the surface compressive stress (CS) and the depth of the stress layer (DOL) of the glass are measured. The results are shown in Table 9. It can be seen from the data in Table 9 that both the CS and DOL of the glass with bubbles decrease.
