Q: A friend of mine has a huge set of china (at least, I think it’s china) marked “JAJ” over a crown and “Made in England.” Can you tell us the maker and possibly the history behind it?

 

A: Your friend has a set of Pyrex, not china, made by James A. Jobling, a company in Sunderland, England. Pyrex is a heat-resistant glass first made in 1915 by the Corning Glass Works. James A. Jobling obtained the right to make Pyrex in 1921 and began producing it in 1922. The company became part of Corning, Ltd. in 1973. The Jobling factory was sold to the Newell Company in 1994. Arc International, a French company, bought Newell’s European division and the licenses for Pyrex in 2005. The Sunderland plant was closed in 2007 and production moved to France. Pyrex is no longer made in England.
