Pyrex is one of the most popular types of kitchen glassware collectibles today. A lot of that has to do with its availability, affordability, durability, variability and of course, its immediate nostalgia factor. Many collectors need not go farther than grandma’s or even their own kitchen to find a piece of Vintage Pyrex. There are tons of different designs and colors of various rarity for collectors to choose from.
Pyrex glassware was introduced to the public in 1915 by the Corning Glass Works. According to Barbara E. Mauzy’s Pyrex: The Unauthorized Collectors Guide, there are 3 basic types of collectible Pyrex: Clear Pyrex Ovenware (introduced in 1915), Pyrex Flameware (1936 - 1979) and Pyrex Colors (1947 - ?). Of the three types, most people are familiar with the Colored Pyrexware because it is very distinct and there is a considerable amount of it still being used in households. There is a good chance that any antique store or flea market you visit will have a number of Pyrex items for sale.
Rather than trying to reinvent the wheel, we used to link the full history of Pyrex on the official Pyrexware website. It appears that article has been moved (this is actually the SECOND time it was moved - I really wish they would use htaccess redirects for their old articles). Anyhow, I’m not going to link to any page in particular because of that - please visit their website and search for the history of Pyrex there. You can also find histories and other information in the following books:
