Corning said at an event with U.S. President Donald Trump on Thursday that it plans to spend $500 million and create 1,000 jobs in the United States making a new kind of glass for vials and cartridges to hold injectable drugs.
The commitments were made as part of Trump’s “Made in America” week, during which he showcased American-made products and made an impassioned defense of his ‘America First’ policies.
Corning said it developed the new type of glass in collaboration with drugmakers Merck & Co and Pfizer Inc , who were also at the event.

Corning said the commitments were the first part of a planned $4 billion investment in the new pharmaceutical glass. The glass, called Corning Valor Glass, is stronger and more damage-resistant than other pharmaceutical glass, according to Corning.
Corning (GLW) said the investment should eventually create 4,000 new jobs, but it did not provide a time frame for those jobs.
