What’s the first thing a novice collector does when a piece of glassware catches their eye? Why pick it up and look at the bottom of course! But do you know what you’re looking at? Other than the obvious, Pyrex, Corning-ware, Fiesta, Fire King, etc. etc. there’s a whole lot more to be familiar with. But lets start with Pyrex for now, here’s a super helpful GUIDE.
Also, on one of my web searches to identify a piece, I ran across Glass Lovers Glass, a website loaded with information on marks and labels, thought I’d share.
