The Kerr glass plants were bought by Ball Corporation in 1992. Ball later left the glass container business altogether, and sold the plants to Saint-Gobain Containers. S-Gs North American container division later became known as Verallia North America, which was then sold to Ardagh Group in April 2014.

Are Kerr jars still made?

These jars are still in production, and will be a match to any Kerr Regular Mouth Self Sealing Pint that you can buy off the shelf.
