The disclosure relates to glass compositions with high coefficients of thermal expansion and low fracture toughness designed for thermal tempering. These glasses are ideally suited to produce a “dicing” pattern when thermally tempered, even when thin (<3 mm).

Methods of making such glasses are also provided.

The utility model provides toughened glass with a light adjusting effect, which relates to the technical field of toughened glass and comprises outer glass and laminated glass, four corners of the outer glass and four corners of the laminated glass are provided with thinning grooves, corner inserts are fixed on the surfaces of the thinning grooves, buffer corners are slidably connected to the surfaces of the corner inserts, one side of each buffer corner is provided with a sliding groove, and the other side of each buffer corner is provided with a sliding groove.
