While the different variations may look similar, they are not the same. Borosilicate glass is a significant upgrade from traditional glass, and these differences can make a big impact on both us personal health and the environment when compounded over time.

Boroslicate glass can be readily identified by its refractive index. By immersing the glass in a container of a liquid of similar refractive index, the glass will disappear. Such liquids are mineral oils.

Because of its durability and resistance to chemical changes, borosilicate glass has traditionally been used in industrial settings, as well as for kitchenware and premium wine glasses.

When using borosilicate glass the liquid inside remains pure, and because borosilicate glass has low solubility, it keeps your beverage free from contamination.
