The Pyrex Series: Numbering & Sizing

Today we are going to be outlining the numbering and sizing systems of Pyrex. I've tried to include photos along with each of the pieces! All Pyrex is stamped on the bottom of the dish with this kind of information. It will say Pyrex and have the number and size stamped with it as well.
