The vials are also embedded with identifiers visible under black light to prevent counterfeiting. ⁠⠀ ⁠⠀ Most important for protecting the precious cargo, however, is the fact that Corning makes the glass harder to break or crack than standard versions. The vials are soaked in a salt bath bubbling at more than 500 degrees Fahrenheit, a key step in fortifying them from cracks, flakes and breaks.⁠⠀ ⁠⠀ The vial, named Valor, was approved for use by federal health authorities just a few months before the new coronavirus hit. Since then, demand for the containers has surged so much that the glassmaker has bolstered manufacturing to churn out tens of millions a month.⁠⠀ ⁠⠀ Read more at the link in our bio.⁠⠀ ⁠⠀ 📷: @joshua_rashaad for @wsjphotos」11月18日 0時07分
