Abstract: Glasses containing silicon dioxide (SiO2) and/or boron oxide (B2O3) as glass formers and having a refractive index nd of greater than or equal to 1.7, as measured at 587.56 nm, and a density of less than or equal to 4.5 g/cm3, as measured at 25° C., are provided. Optionally, the glasses may be characterized by a low optical dispersion, a high transmittance in the visible and near-ultraviolet (near-UV) range of the electromagnetic spectrum, and/or good glass forming ability.

Abstract: Glasses containing silicon dioxide (SiO2) and/or boron oxide (B2O3) as glass formers and having a refractive index nd of greater than or equal to 1.80, as measured at 587.56 nm, a density of less than or equal to 5.5 g/cm3, as measured at 25° C., and a high transmittance to, particularly to blue light, are provided. Optionally, the glasses may be characterized by a high transmittance in the visible and near-ultraviolet (near-UV) range of the electromagnetic spectrum and/or good glass forming ability.

Abstract: A reusable beverage container contains an insulated cup, a lid, and a straw. The beverage is stored in the insulated cup and an opening of the insulated cup is covered with the lid. The lid is removably attached to the insulated cup with an inner locking lip and an outer locking lip. A gasket can also be used to attach the lid to the insulated cup. The straw traverses into the insulated cup through a straw-receiving hole. The straw is positioned in the straw-receiving hole such that a bias-cut edge of the straw is positioned within the insulated cup and a straight-cut edge of the straw is positioned outside the lid. A stoppage band of the straw prevents the straw from coming out of the lid.
