Ubiquitous in the 1950s and 1960s, vintage Pyrex mixing bowls, refrigerator sets, and casserole dishes are seeing a huge surge in popularity since they’re inexpensive, durable, easy-to-find, and retro-mod. The first set of primary-color mixing bowls came out in the late 1940s, with other colors, patterns, and shapes following through the 1970s. Today, most Pyrex items are clear.

Barbara Mauzy’s book, Pyrex: The Unauthorized Collector’s Guide is a great resource. Find Pyrex online at www.tptt.net or at David G. Baker’s eBay store: stores.ebay.com/Daviddishes.
