I am wondering the best reference that you all know of that will help me identify Pyrex numbers with name and size. I am new to collecting and would like something that I can keep track of shapes, volumes, and manufacturers numbers. I have checked the popular blogs and am struggling. It's probably right in front of my face and I am just not seeing it! HA! I think it would help me learn what is out there. Just hearing #443's, etc is confusing until you learn what they are- hehe! Gotta find a source with all the numbers, so I can memorize them! ;) I know there are some beautiful vintage charts that do this, but is there somewhere on line I can find this until I get my own guide? I want to save my funds for actual Pyrex :) - although it would be really cool to get the chart! Let me know if you know of a good one... Thanks!
