Everything you ever wanted to know about Pyrex from (almost) everywhere but the US. "Dots and Diamonds: Your Guide to International PYREX" by Australian author and collector Stan Savellis. Self-published and available from his website thatretropiece.com. A whopping 480 pgs. full of glossy, professional quality color photos of Pyrex from the UK, Australia, and New Zealand, the likes of which you may have never seen, much less even knew existed, along with in-depth info on all. Weighing in at over 6 pounds(!), shipping from AUS ain't necessarily cheap, but it's worth it. I dare say you won't see a better, more comprehensive treatment of the subject. #dotsanddiamonds #thatretropiece
