The Anchor Hocking Pyrex plant in Charleroi, Washington County plans to shut down for good Friday.
A last batch of glass was made at 7 a.m., ending a 132-year business, known globally for making Pyrex.
Last year, the parent company of Anchor Hocking, a previous competitor, acquired the Charleroi plant.
The Ohio-based company has delayed the plant’s closure three times, citing “operational needs” in December 2024.
Anchor Hocking announced it's moving all operations to a plant in Lancaster, Ohio with more than 200 jobs lost.
