The Race to Make Vials for Coronavirus Vaccines (NewYorker)

The development of Valor Glass began in 2011, when Corning’s researchers were working to reinvent medical vials, which had not changed substantially for a century. Using platinum-lined ceramic crucibles, heated to more than a thousand degrees, they spent hundreds of hours combining silica with new ingredients. They found that, by adding alumina and removing boron, they could make the glass far more resistant to degradation, and therefore less likely to leach contaminants into the contents. Other innovations came later, and the vials went on the market in 2017. This June, the federal government granted Corning more than two hundred million dollars to produce them for COVID vaccines.
